Scientists extract tissue from 80m-year-old dinosaur bone
The fossil is 12 million years older than a previous Tyrannosaurus rex specimen which yielded a similar discovery two years ago, amid much controversy.
The new fossil, a thigh bone, belonged to a plant-eating, duck-billed dinosaur, or hadrosaur. It appeared to be even better preserved than the T-rex bone after being buried deep in sandstone.
