Tawa 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. It was thought to be 2 metres long, 1 metre tall, and 20 kgs.
