NEW HAVEN, Conn., Oct. 15 (UPI) -- The king of the dinosaurs, Tyrannosaurus rex, didn't just have an appetite for other dinosaurs -- it was happy to eat its own kind, U.S. paleontologists say.
Yale University researcher Nick Longrich was examining dinosaur bones for mammal tooth marks when he discovered a bone with exceptionally large gouges that could only have been made by T. rex -- but the bone in question was also from T. rex, a university release said Friday.
