Two new species of horned dinosaurs were discovered to have lived in Utah 76 million years ago when the U.S. state was part of an island continent.
One of the giant reptiles, dubbed the Utahceratops gettyi, had a 7-foot-long head. The other, called Kosmoceratops richardsoni, the most-ornate dinosaur ever unearthed, had 15 horns: 1 over the nose, 1 over each eye and at the tip of each cheekbone, and 10 across the back of its bony frill. Each dinosaur was about as heavy as a hippopotamus.
