How did the Dinosaurs catch food?

Baby Blue tilted his head, his brow furrowed in thought. He remembered the T-Rex's massive jaws and sharp teeth. "Well," he began, "the big ones, like the Tyrannosaurus Rex, they had really sharp teeth, didn't they? Like big, pointy knives! They probably used them to grab and tear their food." He mimed a fierce bite with his paws.

Russo chimed in, remembering the Triceratops. "And the Triceratops had that big horn on its nose! Maybe it used that to push down trees, or to get juicy leaves and branches to eat." He nudged his nose forward, pretending to be a charging Triceratops.
