Bitten by hungry T. rex, this dinosaur got away

Researchers Robert A. DePalma II, left, and David A. Burnham show a Tyrannosaurus rex tooth crown embedded between the vertebrae of a hadrosaur and surrounded by bone overgrowth. That regrowth shows the duckbill was alive and not just a carcass when it met the T. rex, so the fossil provides definitive evidence that T. rex hunted live animals, researchers say.
