Triceratops

The three-horned tank of the Late Cretaceous/Dinosaurs & Extinct Animals

Triceratops is one of the most recognizable dinosaurs, thanks to its three facial horns and enormous bony frill. Living about 68 to 66 million years ago in what is now North America, it was one of the last non-avian dinosaurs. Despite its fearsome appearance, Triceratops was a herbivore that used its beak-like mouth and shearing teeth to process tough vegetation. Fossil evidence suggests they may have lived in herds and that their frills and horns were used in both defense and display.
