Dodo (Raphus cucullatus)

(Photo from Smithsonian Magazine)

Extinction Date- 1681

Habitat- Island of Mauritius

Size (Weight/Length)- 22 kg; 90 cm tall

Diet- Fruits; Nuts; Roots; Seeds

Cool Facts- As dodos went extinct in the 1600’s, we only know what they look like from incomplete skeletons and illustrations. These large birds were found only on the tiny Island of Mauritius off the coast of Madagascar. Little is known about their behavior but their skeletons imply they could run extremely fast despite being unable to fly. Their large beak may have been used in territorial displays due to the Island’s limited resources. They were primarily vegetarians but would occasionally eat a crab or shellfish. People first visited the Island of Mauritius in 1507 and the dodos were quickly hunted by people and invasive species alike due to their flightless and fearless behavior. Today, the near threatened Nicobar pigeon is their closest relative. Cracking down on the illegal pet trade and their illegal poaching has resulted in the Nicobar pigeon doing much better than their long since passed relative.

Currently working on a erythra archeology diorama with subfossils and a spire statue

quick question,

Two Gecko Subfossils

Kawekaweau

I drew some gecko subfossils. Kawekaweau is the largest known gecko to have lived being over 60cm. It is thought to be the Kawekaweau from Maori folklore. Because it was a subfossil, instead of on a rock, I drew the gecko on a jar of alcohol, as a specimen was thought to have been preserved in alcohol before being stuffed.

Phelsuma gigas

Nocturnal (active during the night) animals like most geckos usually have vertical pupils whereas, diurnal (active during the day) animals more commonly have circular pupils. Tetrapods have two types of light sensing cells: rods and cones. Rods detect light and cones detect different colours as there are multiple types of cones. There are some exceptions like the diurnal Auckland Green Gecko which has vertical pupils and frogs which have two types of rod cells, so they can actually distinguish blue from green at really low light levels. 

Because rods are more sensitive to light than cones, nocturnal animals tend to have more rods than cones and diurnal animals tend to have more cones than rods in favour of better colour vision. Geckos evolved from diurnal lizards. Because gecko’s ancestors were diurnal they lost their rod cells. When geckos ancestors then became nocturnal instead of re-evolving rods their cone cells just expanded and became more sensitive to light. Because of this, geckos can see colour at night. Some geckos then became diurnal again like the ancestors of day geckos. The seemingly extinct day gecko Phelsuma gigas actually then became nocturnal again. Day geckos usually have circular pupils whereas, Phelsuma gigas apparently had vertical pupils.

Humans have three types of cone cells that are most sensitive to either red, green or blue. Geckos also have three cone cells, but they instead have green, blue and ultraviolet cones.

Eurasian Aurochs (Bos primigenius)

(Photo from Britannica)

Extinction Date- 1627

Habitat- Europe; Northern Africa; Central Asia

Size (Weight/Length)- 1,000 kg; 1.8 m tall

Diet- Grasses; Nuts; Leaves

Cool Facts- The Eurasian aurochs was a majestic species of megafauna cattle that lived throughout the Pleistocene. Aurochs were believed to live in small herds and have a similar hierarchy to their current descendents of domesticated cattle. Due to their massive size, Eurasian aurochs had little to fear outside of prides of lions or large tigers. Their cultural significance travels throughout the Neolithic peoples of Asia, Africa, and Europe. Aurochs were favored creatures for cave paintings and fights in the Roman Colosseum. Domestication of aurochs began in the Fertile Crescent when humans began civilization. Unfortunately, Eurasian aurochs were driven to extinction by over-hunting and a quickly transforming landscape that resulted in the death of many megafauna species. Today, their closest relative is the rare, Spanish Pajuna cattle.
