Triceratops with its 3 horns, a parrot-like beak and a large frill that could reach nearly 1 metre across, the Triceratops skull is one of the largest and most striking of any land animal.
The horns could have been used to fend off attacks from Tyrannosaurus. A partialTriceratops fossil collected in 1997 has a horn that was bitten off, with bite marks that match Tyrannosaurus. The fossil shows that the horn healed after being bitten, so at least some Triceratops survived these encounters.
Puncture marks on fossil frills show that male Triceratops also used their horns to fight each other, probably to impress females.
