Scientists just found dinosaur blood that survived 115 million years
Scientists have discovered chemically confirmed traces of ancient blood inside 115-million-year-old dinosaur bones, challenging assumptions about how long biological molecules can survive. The extraordinary preservation could unlock new clues about dinosaur physiology and even help scientists search for ancient life elsewhere in the universe.

Scientists Say They've Found Preserved Dinosaur Blood in a 115-Million-Year-Old Fossil, but Not Everyone Is Convinced
Soft tissues like blood generally break down relatively quickly after death. Environmental factors can also produce red blood cell look-alikes, so many outside researchers are cautious about the new study's claims

Dinosaur Blood Found In Fossils For the First Time
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. Popular Science reports: The evidence exists inside the fossilized limb bones of a juvenile Aratasaurus museunacionali. Discovered in 2008, A. museunacionali was an Early
