Triceratops

Meet Triceratops

• Triceratops apparently fought with each other often. Most adult Triceratops horns have evidence of rough battles where they scraped so hard they left grooves in the bone itself.

• The Triceratops skull at SMM has a healed injury where the right side of its face was punctured by the horn of another Triceratops.

• The big frill on the back of its head would have protected its neck from attack from other dinosaurs and the horns of other Triceratops.

• Triceratops lived at the same time and place as Tyrannosaurus rex.

• Triceratops’ hearing was more tuned to low frequencies, and not high, sharp sounds.
