Triceratops had the biggest skull of any land animal ever known. Tip-of-snout to back-of-frill, an adult Triceratops’s head could measure 10 feet long - about the length of a small car. That’s a head!
The three horns are what gave Triceratops its name (literally “three-horned face”): two long horns above its eyes and a smaller one on its snout. The huge bony frill behind its head probably protected its neck from T. rex bites, but it was also likely covered in skin and brightly colored for display - like a peacock’s tail, only made of bone.
Its mouth held up to 800 teeth at any one time, packed into “dental batteries” that worked like grinding plates. Worn-out teeth were constantly replaced by new ones - so Triceratops chewed its way through tough plants for its entire life.
