 of the late Cretaceous period. Because of some variations in sample fossils, it was thought at one time that there were as many as 16 different species, but only one species, Triceratops horridus is currently recognized. It is characterized by its three horns, one on the nose and one over each eye, and a large bony frill projecting backward from the skull, which probably served to protect the neck and fore part of the body. The head was large (about 8 ft/2.4 m long), the body (about 20 ft/6 m long) was bulky and barrel shaped, and the limbs were massive and of equal length. Fossil specimens have been found in the W United States and Canada. It belongs to the group of horned dinosaurs, the ceratopsians.

Triceratops

 

a genus of fossil reptiles of the suborder Ceratopsidae. Triceratops lived at the end of the late Cretaceous. It measured as much as 6 m in length and had three horns on its head: one short nasal horn and two long frontal ones. Physically, Triceratops resembled a rhinoceros much more than it did reptiles. It moved about on four massive extremities and fed on herbaceous vegetation. Remains are known from deposits in North America.
