This is a life-size cast of a male Tyrannosaurus rex skull. Found by Barnum Brown in Montana in 1906, the original is on display at the American Museum of Natural History in New York City. It was only the third rex ever found.
T-rex was the largest land predator ever. Its massive skull was capable of tearing a 400 lb. piece of flesh from its prey.
