In 2007, a groundbreaking discovery changed paleontology forever: scientists extracted actual protein from a 68-million-year-old Tyrannosaurus rex bone! Using advanced techniques normally used in cancer research, Mary Schweitzer’s team identified collagen fragment, three of which matched modern chicken proteins.
This astonishing find not only proved that birds are the living descendants of dinosaurs, but also overturned the belief that proteins can’t survive for tens of millions of years. It opened the door to a whole new field of ancient biomolecule research, pushing us closer to decoding the deep past.
