Sinornithosaurus was a dromaeosaurid dinosaur from Early Cretaceous China. It was possibly the only venomous dinosaur.
In Planet DinosaurEdit
Sinornithosaurus appeared in the episode `Feathered Dragons` where it's first seen chasing a Microraptor through the trees. The Sinornithosaurus eventually gave up. It was later seen in a pack hunted a female Jeholosaurus who had young. Using their venom, they successfully killed the mother.
- Sinornithosaurus has an extremely similar model to Rahonavis in Planet Dinosaur.
