Pentaceratops is a genus of ceratopsid dinosaur from the late Cretaceous Period of what is now North America. Its name means "five-horned face" in reference to its two long epijugal bones, spikes which protrude out sideward’s from under its eyes, in addition to the three more obvious horns.

Pentaceratops lived around 75-73 million years ago, its remains having been mostly found in the Kirtland Formation in the San Juan Basin in New Mexico.

It was about 8 m (27 ft) long, and has been estimated to have weighed around 5,500 kg (13,000 lb)
