SALT LAKE CITY – Scientists said Wednesday they've discovered fossils in the southern Utah desert of two new dinosaur species closely related to the Triceratops, including one with 15 horns on its large head.
The discovery of the new plant-eating species — including Kosmoceratops richardsoni, considered the most ornate-headed dinosaur known to man — was reported Wednesday in the online scientific journal PLoS ONE, produced by the Public Library of Science.
The other dinosaur, which has five horns and is the larger of the two, was dubbed Utahceratops gettyi.
The Utahceratops has a large horn over the nose and short eye horns that project to the side rather than upward, similar to a bison. Its skull is about 7 feet long, it stood about 6 feet high and was 18 to 22 feet long. It is believed to have weighed about 3 to 4 tons.
The Kosmoceratops has similar facial features at the Utahceratops, but has 10 horns across the rear margin of its bony frill that point downward and outward. It weighed about 2.5 tons and was about 15 feet long.
The horns on both animals range in length from about 6 inches to 1 foot.
