Cryolophosaurus es un terópodo basal y el primero encontrado en la Antártida. Vivió a principios del período Jurásico y posiblemente sea uno de los tetanuros más antiguos conocidos. El cerebro de Cryolophosaurus también era más primitivo que los de otros terópodos.
Con base en la evidencia de especies relacionadas y estudios de textura ósea, se cree que esta extraña cresta se uso para el reconocimiento dentro de la especie, intimidar/combatir con rivales en el grupo o intimidar depredadores potenciales de otras especies.
Aquí se lo ve representado como un busto escala 1/6 del tamaño real (comisión).

BIRB! I love how pictures of Standard-winged nightjars come with the subject either half asleep or "WHAT ARE YOU DOING IN MY HOUSE" haha! The breeding males aren't very standard in their wings though, so I don't know why that's their common name. Once per breeding season, many of the males grow one feather on each wing that is longer than their body. I think this only happen in roughly 5 out of the 39 species within the genus. Also, "longipennis" actually means "Long wings" so I REALLY don't know why they called it "standard" in English! Why are they called that!?
Isisaurus colberti was a sauropod dinosaur that lived in what is now India and Pakistan at the end of the Cretaceous Period, about 70-66 million years ago.
It was part of the titanosaur group of sauropods and had some unusual proportions* compared to its close relatives, with elongated forelimbs and a relatively short chunky neck. Since it's only known from a partial skeleton its full size is unknown – estimates have been made as large as 18m long (~60') but it was probably somewhat smaller, closer to around 11m in length (36').
(*Measurement errors in the original paper resulted in some very weird proportions, but more recent and rigorous reconstructions have made Isisaurus not quite so cursed-looking.)
Like most other titanosaurs it probably lacked the thumb claws seen in other sauropods, and it may also have had some bony osteoderm armor studding its skin.
Coprolites that may represent Isisaurus' poop show evidence of several different fungi that grow on tree leaves in humid tropical and subtropical climates, suggesting that this sauropod was a selective browser somewhat like modern giraffes.
