Triceratops is one of the most iconic dinosaurs of all time. This large, three-horned herbivore lived in western North America during the Late Cretaceous and is famous for its massive skull, broad frill, and powerful horns.
Appearance
Triceratops had a strong body, a parrot-like beak, and a large bony frill extending from the back of its skull. Two long brow horns and a shorter nose horn gave it a distinctive silhouette and may have played roles in defense and display.
Size
Length: 8–9 m (26–30 ft)
Weight: 6–12 t (6,000–12,000 kg)
Group / clade: Ceratopsian
Diet
As a herbivore, Triceratops fed on plants such as ferns, cycads, and other tough vegetation. Its beak helped clip plant material, while its cheek teeth formed efficient slicing surfaces for chewing.
Habitat and Range
Triceratops lived on floodplains and forested regions of Late Cretaceous North America. Fossils are especially common in the Hell Creek Formation and the Lance Formation, indicating it was widespread and abundant in its environment.
Behavior and Defense
The horns and frill likely served multiple functions. The horns could have been used for defense against predators, while the frill and horn shapes may have helped with display, species recognition, and possibly social interactions.
Discovery
Triceratops was described in the late 19th century and has since become one of the best-studied ceratopsians. Numerous fossils—including skulls and partial skeletons—have helped scientists learn about its growth, variation, and life history.
