Protohadros

About Protohadros The dinosaur Protohadros appeared on the Earth around 95 million years ago. This was a time of warmth and ample vegetation on the Earth. Protohadros was a hadrosaur, or duckbilled dinosaur. It possessed a long duck-like beak, which contained no teeth. Further back within its mouth were rows of possibly thousands of small teeth, which it used to crush plant material before swallowing it. Scientists believe that Protohadros, which was discovered in 1994 by Gary Byrd could have been the ancestor for all the other duckbilled dinosaurs. If not the ancestor, it was certainly one of the first. Protohadros had powerful hind legs, which it used for quick movement. The front legs were smaller and weaker. both front and rear legs ended in hoof-like claws.
