T. Rex Apparently Picked Bones Clean

Tyrannosaurus rex scraped the meat from the ribs of its prey in much the same way a human might gnaw on a serving of barbecued ribs, a meeting of Geological Society of America was told Tuesday.

Bite marks on fossil bones showed evidence that the fearsome dinosaurs used their dagger-like teeth with some dexterity to remove the meat from bones before munching on them like a modern-day dog, Daniel Hyslop of the University of Wisconsin said.

Fossilized bones contain puncture holes that exactly match the conical, serrated teeth of T. rex, Hyslop found.
