Researchers have confirmed the presence of intact biomolecules and mineralized red blood cells inside the 115-million-year-old fossilized bones of a juvenile Aratasaurus museunacionali from Brazil. The discovery challenges assumptions about how long blood-related biomolecules can survive and could help scientists study dinosaur metabolism, blood evolution and even how traces of ancient life might be preserved on other worlds.
