A close relative of Dilophosaurus, Gojirasaurus was one of the largest predators during the Triassic. It is estimated to be about 16-20 feet long and weighed around 800-1,000 pounds. Only one specimen has been found. This skeleton is far from complete, but provides just enough information to paint a picture of this animal. Gojirasaurus lived about 220 million years ago in North America.
