Dinilysia (name meaning "Terrible Ilysia") is a genus of snake that originated during the Late Cretaceous period in what is now North and South America. Measuring 3 meters in length, Dinilysia was some of the earliest, if not, the earliest known snakes.
In the Series 2 finale, "Fall of a Kingdom Part II: Return of the King", a single pregnant female Dinilysia was brought back to the park from Prehistoric Montana 65 million years ago.
Era & DiscoveryEdit
Dinilysia lived in North and South America during the Late Cretaceous period, over 85-65 million years ago. It shared the environment with the dinosaurs and earlier mammals like Didelphodon. The snake was discovered in 1901.
Dinilysia measured 6-10 feet long, which was large for a primitive snake. As a species of Late Cretaceous snake, during their time, these reptiles had only recently evolved from the same family as lizards, but by then, the specialized in hunting warm-blooded creatures such as mammals. To do this, they used special sensory pits on their snouts as a way of detecting the heat signatures of other animals.
- Dinilysia was the first and smallest prehistoric snake to be brought to the park.
