Rare Dinosaur Skull Found in National Park

A University of Chicago undergraduate spied a fossil bone sticking out of the Texas desert and discovered the only complete skull ever found of the three-horned Chasmosaurus, a newspaper reported Monday.

The four-foot-long fossil was found in Big Bend National Park. The dinosaur lived about 80 million years ago in the Mesozoic marshes and ocean beaches of southern Texas, the Houston Post said.
