Dinosaur Wiki

Tawa hallae is the name given to a very recently (as of December 2009) discovered dinosaur, thought to be an ancestor of Tyrannosaurus. It is named after a Pueblo sun god. Tawa is thought to have feathers, very unusual for a Triassic dinosaur! It is thought to have lived around 215mya, in the Middle Triassic. Not very much is known about Tawa, but hope is that extensive research and analysis will help unlock the history of the dinosaurs' evolutionary chain. Maybe proof will appear that it is related to Tyrannosaurus, after all.

As very little is known about Tawa, it is very difficult to accurately tell its eating habits. However, it is most likely that it lived on similar diets to Herrerasaurus and Eoraptor, mainly eating small lizards, insects and carrion. It is unknown as to whether or not it turned to cannibalism in hard times, like Coelophysis.
