Triceratops is one of the very first dinosaurs to be discovered. A famous paleontologist, Othneil Marsh, working at Yale University, first described and named Triceratops in 1889. Many skeletons have been collected over the years since, but until very recently, only adults were found. Then, about 15 years ago, a tiny Triceratops skull was collected. It shows clearly the tiny horns and short frill that marks it as a baby.
Did you Know: Triceratops lived in herds, like modern bison. This gives each member of the herd protection from attack by carnivores. This is particularly important for the babies, which are too small to defend themselves and too slow to escape. Because they had protection of the herd, they did not need large horns.
