'Triceratops horridus' cut a formidable figure in the prehistoric landscape due to its enormous head that was ornamented with three horns and a bony frill studded with spikes. With its three sharp horns and spiky head plate, 'Triceratops horridus' must have been an intimidating presence as it trampled across western North America in the late Cretaceous period, some 69 million years ago.

Although it might appear dangerous, its beak-like mouth was best suited for grasping and plucking rather than biting, according to a 1996 analysis in the journal Evolution. It also likely used its horns and bulk to tip over taller plants.
