CAIRO, EGYPTâAccording to an Ahram Onlinereport, a shipyard that was in use as early as the fourth century B.C. has been uncovered at the Tel Abu Saifi archaeological site in the northern Sinai Peninsula. Equipped with two dry dockyards, the workshop was located on a branch of the Nile near the Roman fortress of Silla. Mostafa Waziri of the Supreme Council of Antiquities said blocks from the shipyardâs limestone building were reused in other structures when the branch of the Nile dried up. Wooden beams, shipwrecks, bronze and iron nails, fish bones, and pottery were also found.

TWO-STORY HOMES WITH BALCONIES UNEARTHED IN POMPEII
A team of archaeologists at Pompeii has uncovered an alleyway of grand houses, with balconies left mostly intact and still in their original hues.
"This type of find is a novelty for this area of Pompeii,"a spokesperson for the archaeological site said in a statement shared to social media. "Almost two thousand years from the eruption of 79 AD, Pompeii continues to give us treasures."
The discovery is unusual not just for the colour preservation, which will allow visitors to the site to see the houses almost exactly as the city's original residents did, but also because it is so unusual in Pompeii for upper stories to have been preserved.
This is because the city was buried from above, unlike nearby Herculaneum for example which was buried by volcanic ash from the ground up. Located further from the volcano than Herculaneum, Pompeii was also buried in a less thick layer of debris (four metres on average, compared to over 20 in Herculaneum), which meant conservation of the upper floors was rarer.
A series of buildings with three large balconies have emerged in an area now being excavated. On one of the balconies, pots of wine lying on their side [were also found, which were] probably put out to dry in the sun," the statement continued.
Experts will now restore the houses, which will be open to the public as part of a new tour route at the popular site once the necessary work has been completed.
The street is the latest in a series of novel finds over the past few weeks, with excavations underway to stabilize walls at risk of collapse. Just a week earlier, archaeologists were able to cast the complete figure of a horse for the first time ever at the site. Along with a pig and a dog, it is one of the few animals of any species to be successfully cast at Pompeii.
And a month earlier, an excavation uncovered the complete skeleton of a young child in a bathhouse long thought to have been fully excavated. That find was the first time a complete skeleton has been discovered at Pompeii in some 20 years, and the first time a child's remains have come to light in around half a century.

DNA REFLECTS HISTORY OF MIGRATIONS IN SOUTHEAST ASIA
People who moved out of southern China cultivated big changes across ancient Southeast Asia, a new analysis of ancient human DNA finds.
Chinese rice and millet farmers spread south into a region stretching from Vietnam to Myanmar. There, they mated with local hunter-gatherers in two main pulses, first around 4,000 years ago, and again two millennia later, says a team led by Harvard Medical School geneticist Mark Lipson. Those population movements brought agriculture to the region and triggered the spread of Austroasiatic languages that are still spoken in parts of South and Southeast Asia, the scientists conclude online May 17 in Science.
Over the past 20 years, accumulating archaeological evidence has pointed to the emergence of rice farming in Southeast Asia between 4,500 and 4,000 years ago, accompanied by tools and pottery showing links to southern China. Austroasiatic languages now found from Vietnam to India contain words for rice and agriculture, suggesting that ancient arrivals from southern China spoke an Austroasiatic tongue. Questions have remained, though, about where Austroasiatic languages originated and whether knowledge about farming practices, rather than farmers themselves, spread from China into Southeast Asia.
Now, DNA from ancient Southeast Asians provides âclinching evidenceâ for the spread of farming via southern Chinese groups, says archaeologist Charles Higham of the University of Otago in Dunedin, New Zealand, who did not participate in the study. The new report aligns with other ancient DNA evidence of culture-changing population movements across parts of Asia starting around 5,000 years ago (SN: 11/25/17, p. 16). âAncient human DNA is showing that prehistoric people were far more mobile and exploratory than has often been thought,â Higham says.
Lipsonâs team obtained DNA from 18 human skeletons unearthed at five Southeast Asian sites dating to between around 4,100 and 1,700 years ago. These sites are located in Vietnam, Myanmar, Thailand and Cambodia.
DNA preserves poorly in such hot, humid regions. A group led by study coauthor Ron Pinhasi, an archaeologist at the University of Vienna, recently found that human DNA survives best in a skull bone surrounding inner-ear structures that has especially dense tissue. In the new study, DNA was extracted from that bone for each ancient individual.
Roughly 4,000-year-old farmers at Vietnamâs Man Bac site displayed a close genetic relationship to present-day speakers of Austroasiatic languages, especially in southern China, Lipsonâs group says. About 25 to 30 percent of the Man Bac farmersâ ancestry came from hunter-gatherers, the scientists estimate, perhaps due to interbreeding of rice growers and foragers in southern China before any migrations occurred. Many populations today that speak Austroasiatic languages also display a similar genetic signature. Genetic signs of additional hunter-gatherer ancestry, probably acquired in Southeast Asia, appeared in two of eight Man Bac farmers.
At approximately 2,000-year-old sites in Vietnam and Myanmar, farmers inherited a genetic makeup that differed in some ways from that of the earlier Man Bac crowd, but still closely resembled the DNA of present-day inhabitants of southern China. A second southern Chinese migration into Southeast Asia likely led to those DNA tweaks, the researchers say.
New insights into the origin of elongated heads in early medieval Germany
The transition from Late Antiquity to the Middle Ages in Europe is marked by two key events in European history, the fall of the Western Roman Empire and the migration into this Empire by various barbarian tribes such as the Goths, Alemanni, Franks, and Lombards. This resulted in a profound cultural and socioeconomic transformation throughout the continent, and many settlements from this epoch would subsequently develop into the villages and towns we still know today. An international team led by anthropologist Dr. Michaela Harbeck from the Bavarian State Collection for Anthropology and Palaeoanatomy (SAPM) and population geneticist Professor Joachim Burger of Johannes Gutenberg University Mainz (JGU) has now performed the first genomic analysis of populations that lived on the former territory of the Roman Empire in Bavaria, Germany, from around 500 AD and provided the first direct look at the complex population dynamics of what has popularly been known as the Migration Period, or "Völkerwanderung" in German. In addition to anthropologists from Mainz and Munich, the team also includes Dr. Krishna Veeramah, a population geneticist from Stony Brook University in the US, as well as colleagues from the United Kingdom and Switzerland.
In an interdisciplinary study funded by the Volkswagen Foundation, the international research team analyzed the ancient genomes of almost 40 early medieval people from southern Germany. While most of the ancient Bavarians looked genetically like Central and Northern Europeans, one group of individuals had a very different and diverse genetic profile. Members of this group were particularly notable in that they were women whose skulls had been artificially deformed at birth. Such enigmatic deformations give the skull a characteristic tower shape and have been found in past populations from across the world and from different periods of time. "Parents wrapped their children's heads with bandages for a few months after birth in order to achieve the desired head shape," explained Dr. Michaela Harbeck. "It is difficult to answer why they carried out this elaborate process, but it was probably used to emulate a certain ideal of beauty or perhaps to indicate a group affiliation." So far, scholars have only speculated about origins of the practice in medieval Europe. "The presence of these elongated skulls in parts of eastern Europe is most commonly attributed to the nomadic Huns, led by Atilla, during their invasion of the Roman Empire from Asia, but the appearance of these skulls in western Europe is more mysterious, as this was very much the fringes of their territory," said Dr. Krishna Veeramah, first author of the study.
By analyzing DNA obtained from these elongated skulls, Professor Joachim Burger's team revealed that these women likely migrated to early Bavarian settlements from eastern Europe. "Although there is evidence that there was some genetic contribution from Central Asia, the genomic analysis points to the fact that women with deformed skulls in this region are genetically most similar to today's south eastern Europeans, and that the Huns likely played only a minor role in directly transmitting this tradition to Bavaria," Burger noted. Besides their deformed skulls, these women also tended to have darker hair and eye color than the other Bavarians they were buried and probably lived with, who primarily had fair hair and blue eyes.
But the migration of females to Bavaria did not only involve those possessing elongated skulls. Only a little later, two women can be identified who most closely resemble modern Greeks and Turks. In contrast, there was no evidence of men with drastically different genetic profiles. "Most of these foreign women are found with grave goods that look unremarkable compared to the rest of the buried population," added Veeramah. "These cases of female migration would have been invisible from the material culture alone."
"This is an example of long-range female mobility that bridges larger cultural spaces and may have been a way for distant groups to form new strategic alliances during this time of great political upheaval in the absence of a previous Roman hegemony," stated Burger. "We must expect that many more unprecedented population-dynamic phenomena have contributed to the genesis of our early cities and villages."
"Interestingly, though our results are preliminary, there are no major traces of genetic ancestry in these early inhabitants of Bavaria that might have come from soldiers of the Roman army," said Harbeck. "We need to keep investigating on an even broader basis how much Celtic and Roman ancestry is in these early Bavarians."

10 OLDEST SHIPS IN THE WORLD WHICH HAVE SURVIVED TO THIS DAY
10. Â Gokstad ship 900 CE
The Gokstad ship is a 9th-century Viking ship found in a burial mound at Gokstad in Sandar, Sandefjord, Vestfold, Norway. It is currently on display at the Viking Ship Museum in Oslo, Norway.Â
9. Oseberg ship â 820 CE
The Oseberg ship is a well-preserved Viking ship discovered in a large burial mound at the Oseberg farm near TĂžnsberg in Vestfold county, Norway. This ship is commonly acknowledged to be among the finer artifacts to have survived from the Viking Era. The ship and some of its contents are displayed at the Viking Ship Museum at BygdĂžy on the western side of Oslo, Norway.
8. Ancient Galilee Boat 50 BCE â 70 CE
The Ancient Galilee Boat, also known as the Jesus Boat, is an ancient fishing boat from the 1st century AD, discovered in 1986 on the north-west shore of the Sea of Galilee in Israel.
7. Â Nemi Ships 37-41 CE
The Nemi Ships were two ships, one ship larger than the other, built by the Roman emperor Caligula in the 1st century AD at Lake Nemi. Although the purpose of the ships is only speculated upon, the larger ship was essentially an elaborate floating palace, which contained quantities of marble, mosaic floors, heating and plumbing and amenities such as baths.
6. Kyrenia ship  400-300 BCE
The Kyrenia ship is the wreck of a 4th-century BC Greek merchant ship. It was discovered by Greek-Cypriot diving instructor Andreas Cariolou in November 1965 during a storm. Having lost the exact position Cariolou carried out more than 200 dives until he re-discovered the wreck in 1967 close to Kyrenia in Cyprus.
5. Maâagan Michael Ship  400-500 BCE
The Maâagan Michael Ship is a well-preserved 5th-century BCE boat discovered off the coast of Kibbutz Maâagan Michael, Israel, in 1985.Â
4. Dover Bronze Age boat â 1500 BCE
Dover Bronze Age boat is one of fewer than 20 Bronze Age boats so far found in Britain. It dates to 1575â1520 BC, which may make it the oldest significantly intact boat in the world.
3. Â Khufu ship â 2500 BCE
The Khufu ship is an intact full-size vessel from Ancient Egypt that was sealed into a pit in the Giza pyramid complex at the foot of the Great Pyramid of Giza around 2500 BC. The ship now is preserved in the Giza Solar boat museum. The ship was almost certainly built for Khufu (King Cheops), the second pharaoh of the Fourth Dynasty of the Old Kingdom of Egypt. Like other buried Ancient Egyptian ships, it was apparently part of the extensive grave goods intended for use in the afterlife, and contained no bodies, unlike northern European ship burials.
2. Dufuna Canoe â 6550 BCE
Dufuna Canoe is a canoe discovered in 1987 by a Fulani cattle herdsman a few kilometers from the village of Dufuna in the Fune Local Government Area, not far from the Komadugu Gana River, in Yobe State, Nigeria. Radiocarbon dating of a sample of charcoal found near the site dates the canoe at 8500 to 8000 years old, linking the site to Lake Mega Chad.
1. Pesse canoe â 8040 BCE
The Pesse canoe is believed to be the worldâs oldest known boat, and certainly the oldest canoe. Carbon dating indicates that the boat was constructed during the early mesolithic period between 8040 BCE and 7510 BCE. It is currently housed in the Drents Museum in Assen, Netherlands.
Did children build the ancient Egyptian city of Amarna? - Mary Shepperson
New evidence from Akhenatenâs capital suggests that a âdisposableâ workforce of children and teenagers provided much of the labour for the cityâs construction
Thereâs a whiff of magic about the site of Tell el-Amarna that makes the hair on the back of my neck stand on end. Itâs partly down to the effort of imagination needed to conjure a great capital of ancient Egypt from the sea of low humps stretching between the cultivation and the desert cliffs, and partly the long shadows cast by its founders â the âhereticâ pharaoh Akhenaten and his queen Nefertiti.
Amarna came and went in an archaeological moment. It rose and fell with Akhenaten and his religious reformation, under which Egyptâs ancient pantheon of gods was briefly usurped by the worship of a single solar deity; the Aten.
On an uninhabited stretch of the Nileâs east bank, Amarna was founded, constructed and abandoned in under fifteen years. When Akhenaten died in 1332 BC, Egyptâs ancient religion was restored under his successor Tutankhamun and the heretical city of Amarna was flattened and forgotten.
Recent research at the site has focused on Amarnaâs cemeteries; not the flashy rock-cut tombs of the royal family and its courtiers, but the simple desert graves of the ordinary Egyptians who lived and worked in Akhenatenâs city and never got to leave.

Between 2006 and 2013 I was lucky enough to work for the Amarna Project on an excavation which aimed to recover four hundred individuals from a large cemetery behind the South Tombs cliffs, estimated to contain around six thousand badly looted burials. The study of these burials and their human remains has opened a new research window on life and death in the lower echelons of Egyptian society. They paint a picture of poverty, hard work, poor diet, ill-health, frequent injury and relatively early death.
In other respects the South Tombs Cemetery remains were fairly in line with expectations. There were modest variations in the wealth and style of burial, there was a fairly even mix of male to female individuals, and the age distribution showed the usual pattern for ancient populations; high infant mortality giving way to fewer deaths as children survive into early adulthood, with the death rate then rising again as adults succumb to illness, childbirth, injuries and age. This was all important and highly interesting, but not particularly unusual.
The North Tombs Cemetery
In 2015 we began excavating another non-elite cemetery in a wadi behind a further set of courtiersâ tombs at the northern end of the city, and here the tale takes a stranger turn. As we started to get the first skeletons out of the ground it was immediately clear that the burials were even simpler than at the South Tombs Cemetery, with almost no grave goods provided for the dead and only rough matting used to wrap the bodies.
As the season progressed, an even weirder trend started to become clear to the excavators. Almost all the skeletons we exhumed were immature; children, teenagers and young adults, but we werenât really finding any infants or older adults. Our three excavation areas were far apart, spaced across the length of the cemetery, but comparing notes all three areas were giving the same result. This certainly was unusual and not a little bit creepy.
The initial skeletal analysis of 105 individuals excavated at the North Tombs Cemetery in 2015 has now been completed by Dr Gretchen Dabbs of Southern Illinois University, and it seems our initial impressions were absolutely right. More than 90% of the skeletons have an estimated age of between seven and twenty-five years, with the majority of these estimated to be younger than fifteen. Essentially, this is a burial place for adolescents.
This leaves us with some explaining to do. Seven to twenty-five is the age range in which people shouldnât be dying; this is when health should be most robust in a normal population, yet for the people of the North Tombs Cemetery death seems to have come almost exclusively during these years. On the other hand, young infants, which usually abound in ancient cemeteries, are virtually absent with just three of the 105 skeletons estimated to be under seven years old. The North Tombs Cemetery shows the exact opposite of the usual demographic pattern for a cemetery.
The skeletal pathologies at the North Tombs Cemetery also had some curious features. For such a young population, traumatic injuries and degenerative conditions were very common. The majority of 15-25 year-olds had some kind of traumatic injury and around ten percent had developed osteoarthritis. Even in the under 15s, sixteen percent were found to have spinal fractures along with a range of other abnormalities usually associated with heavy workloads.
The most obvious explanation is not a pleasant one: This population seems to have been a workforce of children and teenagers who had to perform frequent heavy labour. Seven years old is about the earliest age that children might be expected to carry a load and follow instructions, hence the absence of younger skeletons. The absence of older adults suggests two possibilities; either workers were released or re-assigned when they reached full adulthood, or the nature of the work and living conditions meant that none of the workers lived much past twenty-five. Indeed, it seems they were lucky to make it to fifteen.
The isolation of these young people in death raises questions about how they lived. Family was very important in ancient Egypt and it was the responsibility of relatives to see that dead family members were properly provided for in the afterlife. The fact that the North Tombs Cemetery dead were buried with little care and virtually no grave goods strongly suggests that they were not returned to their families for burial but lived and died away from the care of relatives.
A further indication of the grimness of life for the young people of the North Tombs Cemetery comes from the multiple burials. 43% of graves contained more than one individual, which is way higher than the small proportion of multiple graves at the other Amarna cemeteries.
At the North Tombs Cemetery the multiple burials, sometimes holding as many as five or six skeletons, contain children of such similar ages that family relationship seems unlikely, while at the South Tombs Cemetery multiple burials appear to represent family groups. South Tombs multiple burials are laid side by side in graves dug to double or triple the usual width, but at the North Tombs Cemetery graves containing more than one skeleton are about the same size as the single burials with the bodies stacked directly on top of each other.
The implication of the North Tombs multiple burials may be that bodies were expected and a grave was dug at the cemetery without knowing how many bodies there would be. Sometimes there was just one body, but if more were delivered the same grave would do for all of them. Whether this collection of casualties was a daily, weekly or monthly occurrence is a matter for bleak speculation, but the cemetery is large, probably containing at least a couple of thousand burials.
Who is buried at the North Tombs Cemetery?
This is a difficult question at this early stage of the project and all our current theories have their drawbacks. The North Tombs Cemetery lies towards the main stone quarries and it seems most likely that these people were employed somewhere in the quarrying process as unskilled labour during the frantic construction of the new city.
A further suggestion is that the North Tombs Cemetery may represent a captured or deported population brought to Amarna for labour. This is perfectly possible and would account for the lack of family contact and the apparent disregard shown for young life. On the other hand, there are no indications from the method of burial, the pottery and the few objects recovered to suggest that these people were not Egyptians.
We hope that future DNA analysis of the bones might clarify the geographical origins of the North Tombs Cemetery skeletons.
In any case, the evidence of the North Tombs Cemetery forces us to face the possibility that Akhenaten built his city at least partly with child labour.
For archaeologists, Amarna is both a blessing and a curse for understanding life in New Kingdom Egypt. On the one hand it provides a snap shot of a city of this period, conceived and built from scratch and not altered in later periods. On the other hand, Amarna is awkwardly exceptional in that it was built at great speed under an eccentric pharaoh and his strange new theology, so how representative might it really be?
If the building of Amarna employed child labour, could it have been a more widespread practice for state building projects in New Kingdom Egypt? At present comparable data from other Egyptian sites is very limited. The exceptional nature of Amarna makes it hard to extrapolate these findings from one highly unusual cemetery.
However, Egypt is littered with building projects of extraordinary scale by ancient standards, from pyramids and temples to canals and artificial lakes, commissioned by pharaohs with a similarly megalomaniac mind-set to Akhenaten. Perhaps when we marvel at these wonders of ancient engineering we should spare more thought for the price paid in human lives, some of them only just beginning, which constituted the cost of such high ambitions. Archaeologygives us the means to provide a counter narrative to the pharaonic bombast of the textual records and tell a grimmer tale of hard work and short lives.
All work at Amarna is carried out with the kind permission and support of the Egyptian Ministry of Antiquities. The work at the North Tombs Cemetery is supported with funding from the National Endowment of the Humanities. The Amarna Project is a project of the McDonald Institute for Archaeological Research, University of Cambridge.
Advances that have allowed us to physically hold 3D printed versions of lost artifacts, or to see 3D representations of ancient structures, have been huge advances in preserving our past. But having a full understanding of how people long ago experienced these objects and buildings goes beyond just seeing them, and how things sound is big part of how we experience our surroundings.
Sharon Gerstel is a Professor of Byzantine Art History and Archeology at UCLA. She spent years studying the art and ritual of churches from the 12th to 15th centuries, but she says that, "recently, let's say in the last 5 years, I've become interested in the sound aspects."
As her interest in the actual sounds of these churches developed, a friend of hers showed her an article in the New York Times about a man named Chris Kyriakakis, who is the director of the Immersive Audio Laboratory in the University of Southern California.
The two of them got together and formed a team to travel to the Greek city of Thessaloniki (which also happens to be Kyriakakis' childhood home) to measure some of these Byzantine-era churches. They did this by setting up speakers and playing a sound pulse (called a "chirp") that, as Kyriakakis puts it, "...excites all of the audible frequencies of sound."
They then record how the chirp sounds from different areas of the church, and using that information, they are able to capture the unique acoustic signature of the space.But they didn't just record strange chirps. They also wanted to hear what could have actually been heard when these churches were built. So had music transcribed by Ioannis Arvanitis and Spyridon Antonopoulos from original Byzantine sources, and they brought in local chanters, Dimos Papatzalakis, Spyridon Antonopoulos, and Nektarios Antoniou, into the churches, and recorded the sounds."The Byzantines described the effect of the mingling of angelic and human voices," Gersteltold us. "So I kept joking, 'are we really recording what the angels sound like?' and I'm not kidding when I say it's almost exactly what it sounded like."
Using the audio signatures they gathered, theywere also able to record chanters in a studio and make it sound like the chanters were inside one of these churches. Kyriakakis says he wants to use these audio signatures to create an "acoustic museum"."When these structures in ten centuries from now, or next year, who knows... we could still for generations preserve what it was like to be in them through our ears. I want to collect as many of these impulses as possible so we can have this museum. That's my dream."
Forensic experts have reconstructed the face of a man who lived around 9,500 years ago in Jericho, near the Jordan River in the West Bank. The reconstruction was based on a micro-CT scan of his skull, which had been covered in plaster and has clamshells for eyes. Alexandra Fletcher of the British Museum, where the skull is housed, believes it and others like it were created as part of an ancestor cult.
The scan reveals that the skull belonged to a man who died after the age of 40 and had a broken nose that healed during his lifetime. In addition, his skull had been tightly bound from early infancy, changing its shape. âThis person lived a very long time ago,â says Fletcher, âbut he could go out shopping in London today, and nobody would turn a hair. Heâs a modern human, just like you or me.â
Ancient Burial Chamber Uncovered in Egypt, With 17 Mummies ... So Far
Archaeological workers in Egypt unearthed an ancient human burial site with at least 17 intact mummies near the Nile Valley city of Minya, according to news agency reports.
The mummies, discovered at a depth of about 25 feet, are believed to be the bodies of priests and officials, The Associated Press reported. The burial ground included sarcophagi made of limestone and clay, animal coffins, and papyrus with Demotic script, not the hieroglyphs found in earlier Egyptian tombs.
The site was discovered near the village of Tuna al-Gabal, the site of a previously excavated necropolis for thousands of mummified animals. It was found last year by some Cairo University students using radar, Reuters reported.
The mummies are believed to be more than 1,500 years old, and date to Egyptâs Greco-Roman period, a 600-year epoch that began in 332 B.C. after the region was conquered by Alexander the Great, said Mohamed Hamza, the dean of archaeology at Cairo University, who helped lead the excavations. Â Â Â
The burial site may hold as many as 32 mummies. It is âthe first human necropolis found in central Egypt with so many mummies,â Salah al-Kholi, an Egyptologist, said, according to The Telegraph.
The countryâs antiquities minister, Khaled Al-Anani, called 2017 a âhistoric yearâ for archaeological discoveries. âItâs as if itâs a message from our ancestors who are lending us a hand to help bring tourists back,â he said at a news conference on Saturday.Egyptâs tourism industry has struggled in recent years. About 5.4 million visitors came to the country in 2016, down from 14.7 million in 2010.The country has had some significant finds this year, including a large statue of an Egyptian ruler found in Cairo in March.

Before being assembled into something recognizable at a museum, most dinosaur fossils look to the casual observer like nothing more than common rocks. No one, however, would confuse the over 110 million-year-old nodosaur fossil for a stone.
The fossil, being unveiled today in Canadaâs Royal Tyrrell Museum of Paleontology, is so well preserved it looks like a statue.
Even more surprising might be its accidental discovery, as unveiled in the June issue of National Geographic magazine.
On March 21, 2011, Shawn Funk was digging in Albertaâs Millennium Mine with a mechanical backhoe, when he hit âsomething much harder than the surrounding rock.â A closer look revealed something that looked like no rock Funk had ever seen, just ârow after row of sandy brown disks, each ringed in gunmetal gray stone.â
What he had found was a 2,500-pound dinosaur fossil, which was soon shipped to the museum in Alberta, where technicians scraped extraneous rock from the fossilized bone and experts examined the specimen.
âI couldnât believe my eyes â it was a dinosaur,â Donald Henderson, the curator of dinosaurs at the museum, told Alberta Oil. âWhen we first saw the pictures we were convinced we were going to see another plesiosaur (a more commonly discovered marine reptile).â
More specifically, it was the snout-to-hips portion of a nodosaur, a âmember of the heavily-armored ankylosaur subgroup,â that roamed during the Cretaceous Period, according to Smithsonian. This group of heavy herbivores, which walked on four legs, likely resembled a cross between a lizard and a lion â but covered in scales.
Unlike its cousins in the ankylosaur subgroup, the nodosaur lacked a bony club at the end of its tail, instead using armor plates, thick knobs and two 20-inch spikes along its armored side for protection, according to the Smithsonian Museum of Natural History.
âThese guys were like four-footed tanks,â dinosaur tracker Ray Stanford told The Washington Post in 2012.
This particular one, according to a news release, was 18 feet long and weighed around 3,000 pounds.
As Michael Greshko wrote for National Geographic, such level of preservation âis a rare as winning the lottery.â He continued:
The more I look at it, the more mind-boggling it becomes. Fossilized remnants of skin still cover the bumpy armor plates dotting the animalâs skull. Its right forefoot lies by its side, its five digits splayed upward. I can count the scales on its sole. Caleb Brown, a postdoctoral researcher at the museum, grins at my astonishment. âWe donât just have a skeleton,â he tells me later. âWe have a dinosaur as it would have been.â
The reason this particular dinosaur was so well preserved is likely due to a stroke of good luck. (Well, perhaps a stroke of bad luck for the poor nodosaur.)
Researchers believe it was on a riverâs edge, perhaps having a drink of water, when a flood swept it downriver.
Eventually, the land creature floated out to the sea â which the mine where it was found once was â and sank to the bottom.
There, minerals quickly âinfiltrated the skin and armor and cradled its back, ensuring that the dead nodosaur would keep its true-to-life form as eonsâ worth of rock piled atop it.â
That is a boon to researchers, particularly given that teeth and bone fragments are much more common finds.
Study claims humans reached the Americas 130,000 years ago
Some 130,000 years ago, scientists say, a mysterious group of ancient people visited the coastline of what is now Southern California. More than 100,000 years before they were supposed to have arrived in the Americas, these unknown people used five heavy stones to break the bones of a mastodon. They cracked open femurs to suck out the marrow and, using the rocks as hammers, scored deep notches in the bone. When finished, they abandoned the materials in the soft, fine soil; one tusk planted upright in the ground like a single flag in the archaeological record. Then the people vanished.
âYou canât push human activity in the New World back 100,000 years based on evidence as inherently ambiguous as broken bones and nondescript stones,â said David Meltzer, an archaeologist at Southern Methodist University. âThey need to do a better job showing nature could not be responsible for those bones and stones.â
The biggest find was a partial skeleton from a single American mastodon. Peculiarly, the largest bones were scarred and broken, but more fragile ribs and vertebrae were still intact. Some of the bones seemed to have been arranged deliberately alongside one another. Many bore the spiral fractures that are a signature of ancient people hammering on fresh bone â either to extract marrow for food or break the bone into tools.
The bones were clustered in groups around a few large, heavy stones known as âcobbles.â The size and makeup of these rocks didnât match the fine-grained surrounding soil. They bore marks you'd expect to see on a hammer and anvil. Scattered around the site were flakes that seem to have been chipped off the cobbles, as though someone had struck the rocks against another solid object. When held up to their source stones, the flakes fit back into them like pieces of a puzzle.
But it was difficult to figure out how old the site was. Any soft tissue in the fossilized bones had long decayed, so scientists couldnât use radiocarbon dating to determine their age. They attempted to date fossils using the uranium-thorium method, which measures radioactive decay of uranium. But the technique was not very reliable at the time, so the Cerutti mastodon remained an enigma.
The breaks on the mastodon fossils looked as though they were human-caused, he said. But to make sure, Holen tried to recreate them using a stone hammer the same size as the one found at the Cerutti site and the skeleton of an elephant that had been recently buried.
âThe bone was extremely fresh and smelled very bad,â Holen said of that experiment. âI almost wished I wasn't doing this.â It took all of Holen's effort â and the help of a younger, stronger colleague â to break the bones. When they succeeded, they recognized the same breakage patterns as the ones found on the fossils. There's no evidence that anyone hunted or butchered the mastodon for meat, but it definitely seemed to him like some human or human cousin had cracked the bones.
âOnce you do the experiment then you really can understand this much better,â Holen said.
Next the team reached out to geochronologist James Paces, who retried the now much-improved uranium-thorium dating technique on the bones. He concluded that they are 130,000 years old, give or take 9,400. This date corresponds with the accepted age of the layer of rock in which the bones and cobbles were found.
But it far exceeds any established date for settlement of the Americas. The oldest biological remains from any humans on the continent is a coprolite (fossilized poop) from 14,300 years ago. Studies based on genetic analysis of modern Native Americans suggest that humans didn't make it over the land bridge that once linked northeast Asia to Alaska until 25,000 years ago.
If the stones and bones really are evidence of people, then who were they? How did they get to this part of the world so long ago? And why haven't we found other evidence of their presence? Did they die out not long after they arrived?
Because there are no hominin remains at the site, and rock hammer technology was used by many hominin species, the scientists caution that discussion of the identity of these people is purely speculative. In a supplement to their Nature paper, they say the Cerutti people may have been Neanderthals, Denisovans (a species known only from a few fragments found in a cave in northern Siberia), or members of the species Homo erectus. It seems unlikely that they were Homo sapiens â anatomically modern humans didn't migrate out of Africa until after 100,000 years ago, according to most estimates.
Otherwise, the first Americans could have used boats to cross the Bering Strait, and then scoot down the Pacific coast â archaeological finds on the Mediterranean island of Crete suggest that hominins were able to cross the sea via boat more than 100,000 years ago.
To some who study American prehistory, this interpretation of the Cerutti site beggars belief. Meltzer called the claim âgrandiose.â Donald Grayson, a paleoanthropologist at the University of Washington, noted that history is rife with examples of scientists misinterpreting strange markings on stone as evidence of human activity. He pointed to the Calico Hills site in the Mojave Desert, which the archaeologist Louis Leakey believed contained 200,000-year-old stone tools. Subsequent studies have largely discredited Leakey's claim â the apparent tools were most likely âgeofacts,â natural stone formations that only look like they were crafted by humans.
âIt is one thing to show that broken bones and modified rocks could have been produced by people, which Holen and his colleagues have done,â Grayson said. âIt is quite another to show that people, and people alone, could have produced those modifications. This, Holen [has] most certainly not done, making this a very easy claim to dismiss.â
Mike Waters, the director of the Center for the Study of the First Americans at Texas A&M, also criticized the claim. To convince him that people were in the Americas so much earlier before the first physical evidence of their remains, he would expect to see âunequivocal stone artifacts,â he said. He doesn't think the cobbles found at the Cerutti mastodon site meet that standard.
Rick Potts, the director of the Human Origins Program at the National Museum of Natural History, was more measured in his appraisal. Though he thought the team's analysis of the bones and stones was thorough, he pointed out a few oddities about the site. For one, it's unusual that people would use hammer stones to process bones but not any sharp-edged tools, even though that technology had been around for more than a million years. For another, as he pointed out, the mastodon's molars were also crushed, and there's no reason he can think of that humans would crack the huge teeth. If those teeth were broken by natural forces, then perhaps the rest of the bones were too.
âIt's not a solid case,â Potts said, âbut my goodness it's a compelling one.â
Briana Pobiner, a paleoanthropologist at NMNH who specializes in studying tooth and tool marks on ancient bones, agreed.
âItâs funny because when I first started reading the paper I didnât see the extra zero and I thought, 'oh, 13,000 years, this sounds good,'" Pobiner said. âAnd then I saw the extra zero and I thought, 'Holy cow!'â
Pobiner acknowledged that the Cerutti site contains less archaeological evidence than scientists would like before making a claim of this magnitude. But as someone who has spent her whole career looking at scratch marks and breakage patterns on bones, the evidence looks to her like it could be human modification.
Erella Hovers, an archaeologist at Hebrew University in Jerusalem who reviewed the paper and wrote an analysis of it for Nature, said she thought the researchers did a thorough job of ruling out natural causes of the particular breakage patterns. She added that the evidence looks much like archaeological sites she has studied in Africa and the Middle East; if the same site was found in that part of the world, she said, people would have fewer questions about it.
The Cerutti site researchers expect to face scrutiny from his colleagues about the paper. That is partly why they have made 3-D images of the mastodon fossils available online.
âI think the models are important in terms of supporting the paper because they allow anyone to look at this evidence in much the same way the co-authors did,â co-author Adam Rountrey, collection manager at the University of Michigan Museum of Paleontology, said in a statement. âItâs fine to be skeptical, but look at the evidence and judge for yourself. Thatâs what weâre trying to encourage by making these models available.â
The scientists also hope that their paper will prompt their colleagues to take a closer look at this period in American history. Perhaps they will find more evidence of hominin presence, bolstering the Cerutti researchers' claim. Or perhaps the mastodon site is a fluke â or a mistake â and they will find nothing at all.
âThe thing to remember is it's a beginning to a new line of inquiry. It doesn't solve anything,â said Hovers. âIt asks new questions.â
The Embracing Pompeii Couple Might Actually Be Two Men
âThe Two Maidensâ of Pompeii have long stood as an iconic image of Pompeiiâs tragic destruction and a symbol of human love. The two bodies, seemingly holding arm in arm, were one of the hundreds of people plastered in ash following the eruption of Mount Vesuvius in 79 CE.
As the nickname suggests, archeologists previously assumed it was two women embracing. However, new research strongly suggests these were actually two men embracing.
Scientific tests of the teeth and skeletal remains have revealed that one was an 18-year-old man and the second was probably a male aged 20 years or older.
"We always imagined that it was an embrace between women. But a CAT scan and DNA have revealed that they are men,â Massimo Osanna, director-general of the Pompeii archaeological site, told The Telegraph.

A Map of Lexical Distances Between Europe's Languages
Europe's defining trait is its diversity. Europeans don't have to travel far to immerse themselves in a different culture. And if each only spoke their own language, they wouldn't even be able to make heads or tails of it.
Or would they?
Finnish people probably won't make a lot out of Spanish, and if you're from Spain, Finnish might as well be Chinese. But not all languages are as far apart as those two. A Frenchman could understand a bit of Spanish, just because it resembles his own language. And an Estonian can pick up a some Finnish, for the same reason.
But the Estonian will have a slightly harder time of it than the Frenchman, and this map shows why.
This linguistic map paints an alternative map of Europe, displaying the language families that populate the continent, and the lexical distance between the languages. The closer that distance, the more words they have in common. The further the distance, the harder the mutual comprehension.
The map shows the language families that cover the continent: large, familiar ones like Germanic, Italic-Romance and Slavic; smaller ones like Celtic, Baltic and Uralic; outliers like Semitic and Turkic; and isolates â orphan languages, without a family: Albanian and Greek.
Obviously, lexical distance is smallest within each language family, and the individual languages are arranged to reflect their relative distance to each other.
Take the Slavics: Serbian, Croatian, Bosnian and Montenegrin are a Siamese quartet of languages, with Slovenian, another of former Yugoslavia's languages, extremely close. Slovakian is halfway between Czech and Croatian. Macedonian is almost indistinguishable from Bulgarian. Belarusian is pretty near to Ukrainian. Russia standa a bit apart, is closest to Bulgarian, but quite far from Polish.
Italian is the vibrant centre of the Italic-Romance family, as close to Portuguese as it is to French. Spanish is a bit further. Romania is an outlier, in lexical as well as geographic distance. Catalan is the missing link between Italian and Spanish. The map also shows a number of fascinating minor Romance languages: Galician, Sardinian, Walloon, Occitan, Friulian, Picard, Franco-Provencal, Aromanian, Asturian and Romansh. Latin, mentioned in the legend but not on the map, although no longer a living language, is an important point of reference, as it is the progenitor of all the Romance languages.
Lots of coldness in the Germanic family. The bigger members English and German, each keep to themselves. Dutch leans towards the German side, Frisian to the English side. Up north, the smaller Nordic languages cluster in close proximity; Danish, Swedish, Norwegian (both the Bokmal and Nynorsk versions). And look at the tiny Icelandic, Faroer and Luxembourgish languages. Aren't they cute?
The Celtic family portrait is a grim picture: small language dots, separated by a lot of mutual incomprehension: the distance is quite far between Breton and Welsh, a bit closer between Irish and Scottish Gaelic, and further still between the first and second pair.
The Baltics constitute the smallest family, but a fatter pair. Still, Latvians and Lithuanians don't seem to be on very good speaking terms with each other.
All the aforementioned language families are part of the wider Indo-Germanic language tribe. Meaning that there are some points of convergence, even if the lexical distance is great. But it's nice to recognise an English fish in the Irish iasc, and to realise that the German Vater and the Greek pateras share an Indo-European root.
Even beyond the wider bonds of the Indo-European language family, some lexical links exist. Between Finnish and Swedish, for example. Not because of linguistics, but because of history and geography, having shared so much of both.
Which explains why even Basque, Europe's most isolated, most mysterious and probably oldest language, shares some distant traits with Spanish and Breton.
The Uralic group consists of two subgroups, one sort of uniting Estonian and Finnish, the other consisting of Hungarian all by itself. Answering the age-old linguistic conundra of whether Finnish and Hungarian are really related (yes) and if so, do they understand each other (somewhat worse than an Albanian and a Frenchman).
No person is an island, nor is any of the languages we speak. But it can be a pretty long swim between all those palavering peninsulas.
