Xianglong

Xianglong was a small, rib-gliding lizard from Early Cretaceous[140-115]China.

Episode 2: Feathered Dragons
It was first seen climbing up a tree. Then, a Microraptor chased it. The lizard glided from tree to tree, with the dinosaur in hot pursuit. Just as the Xianglong was about to glide off a branch, the Microraptor cornered it on the branch, but then, a Sinornithosaurus appeared and attacked the dinosaur, whilst giving the lizard a chance to escape.

Trivia

 * The model used for Xianglong was used in The Great Survivors for the acrodontid lizard.
