A quindeceratops? Scientists have discovered two new species of dinosaur in Utah, one of which has 15 different horns on its head. Both species are considered closely related to the Triceratops. The 15-horned dinosaur, the Kosmoceratops richardsoni, is “the most ornate-headed dinosaur known to man,” according to the Associated Press. The other dinosaur has five horns on its head. Both are plant eaters.
