The Massive Dinosaur Predator That Was Discovered in Antarctica

Introducing the Cryolophosaurus, a 21-foot predator resembling the T-rex in shape and build. Unlike the scaly-skinned T-rex, the Cryolophosaurus sported feathers. It is the oldest known tetanuran and the only specimen from the Early Jurassic Period. This giant tetrapod dinosaur, notable for its unique crest, lived approximately 188 to 194 million years ago during the early Jurassic Period.
