Byronosaurus is a member of the Troodon family. They lived in Asia during the late Cretaceous period. Like Troodons they are very smart, and lived in packs. They are nocturnal and was covered with feathers. It was omnivores and this helped it to avoid competetion with the larger Tyrannosaur of Asia. It appeared in Animal Armeggadon. It was depicted to live in the very end of the Cretaceous period, considered to be a predator and had no feathers. These facts are wrong.
