Astonishing dinosaur mummy has ‘glittering’ skin that was punctured and ripped by ancient crocs

Around 67 million years ago in what is now North Dakota, a duck-billed dinosaur keeled over and died, and crocodiles’ ancient relatives descended on the carcass, tearing holes through the skin and marking up the bones. Today, evidence of the predators’ feast can still be seen in the dino’s fossilized remains, which include remarkable “mummified” skin.

These lingering bite marks may help explain how the dinosaur became a mummy in the first place, a new study suggests. The research, published Wednesday (Oct. 12) in the journal PLOS One (opens in new tab)also proposes that dinosaur mummies with exceptionally well-preserved skin and soft tissues may be more common than scientists once thought.
