With its massive horns and beak-shaped mouth, Triceratops is one of the Museum’s most recognizable dinosaurs. The skull of this 65-million-year-old ceratopsian measures about 8 ft (2.4 m) long—almost a third of its body length. Yet it was much lighter than it looks. In its beak-shaped mouth, Triceratops had between 144 and 160 teeth, which it replaced completely between two and four times over its lifetime.
