Dinosaur Bones Still Have Real Protein Inside After 66 Million Years!

Scientists found something incredible: a dinosaur fossil from 66 million years ago still has the actual protein that was in the dinosaur's bones when it was alive! They used special machines to detect tiny pieces of collagen [the stuff that makes bones strong and flexible], which scientists thought would disappear forever after fossilization. This means fossils might be hiding even MORE secrets about what dinosaurs were really like!
