"Horrible Three-horned Face"
Triceratops was probably a herding animal, like the other Ceratopsians. This hypothesis is supported by the finding of bone beds, large deposits of bones of the same species in an area.
When threatened by predators, Triceratops probably charged into its enemy like the modern-day rhinoceros does. This was probably a very effective defense.
No one knows how Triceratops reproduced or raised their young, except that they probably hatched from eggs.
Triceratops was a ceratopsian, whose intelligence (as measured by its relative brain to body weight, or EQ) was intermediate among the dinosaurs.
Triceratops was hunted and eaten by T. rex. Coprolite (fossilized feces) from a T. rex was recently found in Saskatchewan, Canada by a team led by Karen Chin. This 65 million year old specimen contains chunks of bones from an herbivorous (plant-eating) dinosaur which was eaten by the T. rex. This bone fragment is perhaps part of the head frill of aTriceratops.
Triceratops walked on four short legs; it was a relatively slow dinosaur. Dinosaur speeds are estimated using their morphology (characteristics like leg length and estimated body mass) and fossilized trackways.
LOCATIONS AND DISCOVERY OF FOSSILS
Many Triceratops fossils have been found, mostly in western Canada and the western United States. Paleontologist Othniel Marsh named Triceratops in 1889 - from a fossil found near Denver, Colorado, USA. At first this fossil was mistakenly identified as an extinct species of buffalo. The first Triceratops skull was found in 1888 by John Bell Hatcher. About about 50 Triceratops skulls and some partial skeletons have been found.
Triceratops was a late Ornithischian dinosaur, the order of bird-hipped, herbivorous dinosaurs. It was a member of the suborder Marginocephalia, and the family of large, horned, herding herbivores, the Ceratopsians. The ceratopsians were one of the last major group of dinosaurs to evolve, and include Psittacosaurus, Leptoceratops, Pachyrhinosaurus, Montanoceratops, Chasmosaurus, Centrosaurus, Triceratops, Styracosaurus, Protoceratops, and others.
