Oh god, not'll never look the Triceratops in the same way. A beast of 9 meters in length, with three horns on his head, heavy even 8 tons and today I find out that it was also carnivorous dinosaur ... this is now more terrifying than ever.
More likely an omnivore; it still had grinding molars for processing plant matter. It's teeth were just slightly different from hadrosaurs, which were undoubtedly herbivores.
It makes far more sense then the theory of Rexy being unable to hunt and living completely out of dead animals. Also did you check the link that is in the descriptio about omnivorous behavior?
