Triceratops

Triceratops is a genus of large, four-legged, plant-eating ceratopsian dinosaurs from the Late Cretaceous of western North America.

Updated July 30, 20261 min readCited sources

Triceratops is a large, plant-eating dinosaur from the Late Cretaceous of western North America, known for its three facial horns and bony neck frill. It was one of the last non-avian dinosaurs before the mass extinction 66 million years ago.

What it is

Triceratops was a quadrupedal herbivore with two long brow horns, a shorter nose horn, and a broad frill. Its name means "three-horned face." It lived about 68–66 million years ago in what is now western North America.

Key details

Fossils are relatively common, especially from formations like Hell Creek. The frill and horns were likely used for defence or display. Triceratops teeth were adapted for chewing tough plants. It disappeared in the Cretaceous–Paleogene extinction event.

Why it matters

Triceratops is one of the best-known dinosaurs due to its distinctive appearance and abundant fossils. It helps scientists understand Late Cretaceous ecosystems and ceratopsian evolution. In Canada, its fossils are featured in museum and education collections.

In short

  • Large herbivore with three horns and a frill
  • Lived in western North America near the end of the Cretaceous
  • Fossils are common and well-studied
  • Went extinct 66 million years ago
Canadian angle

Triceratops fossils are reported from North America, including Canada, and the genus is often featured in Canadian museum and education collections about dinosaurs.[7]
