Which dinosaur is famous for its three horns and large frill? Triceratops is the canonical answer.

Triceratops was a large, herbivorous ceratopsian dinosaur that lived in western North America during the Late Cretaceous, about 68 to 66 million years ago. Its name means “three-horned face,” referring to the two long brow horns and the shorter horn above the nose. Behind them was a broad bony frill extending from the back of the skull.

The horns and frill probably served several purposes, including visual display, species recognition, courtship, and competition between individuals. They may also have offered some protection from predators such as Tyrannosaurus. Scientists continue to study healed skull injuries for clues about how Triceratops used its headgear.

The frill was not simply a shield, and its exact role is still discussed. Another source of confusion is Torosaurus, a related horned dinosaur that some researchers have proposed may represent the mature form of Triceratops; this interpretation remains disputed. The quiz answer itself is not disputed.
