Dinilysia was a specialist in hunting the mammals of its time.[1] To do this, they used special sensory pits on their snouts as a way of detecting the heat signatures of other animals.
In Walking with Dinosaurs[]
Death of a Dynasty[]
Two Tyrannosaurus chicks discover a Dinilysia while exploring the area around them. They play with it to the snake's annoyance, but they soon leave it when their mother has a standoff with an Ankylosaurus who was unknowingly intruding the T. rex family's territory.
Behind the Scenes[]
According to the Walking with Dinosaurs website, Dinilysia was the snake that briefly appeared in Death of a Dynasty.
The creature was live-acted by a modern day red-tailed boa. However, the episode in question was set in North America, and Dinilysia lived some 25 million years before Tyrannosaurus and lived in South America.
