Still, there's other evidence the animals liked to mix it up with each other. Triceratops' bony frills were thicker than Centrosaurus and their hornless cousin, Protoceratops. Triceratops also had a thick rim of bone over its eye that meant it couldn't see very well in front, but was probably needed for protection. Michael Ryan of the Cleveland Museum of Natural History said mating and display were just part of the equation -- the horns must have served as defense from antiquity's greatest predator, Tyrannosaurus Rex. Though he agreed Triceratops probably did fight amongst themselves, some of the wounds Farke observed probably came from T. Rex attacks. "As the biggest meat eater around, a full-grown adult T. Rex had only one option to feed itself; the largest prey, Triceratops," Ryan said. "It's clear that these animals came in contact." Related Links: |
