Gasosaurus was a mid-sized predator from Asia. Although known from somewhat incomplete remains, Gasosaurus is estimated to be around 13-16 feet long and about 700-1,000 pounds. Gasosaurus is considered to be a basal coelurosaurian dinosaur. However, it's remains are too incomplete to place it in a specific family and some argue it could be a carnosaur. Gasosaurus lived in Asia about 170 million years ago.
