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

Fossilised red blood cells found in 115m-year-old dinosaur’s bone, say scientists
Chemical tests on Aratasaurus bone identify presence of heme, the organic compound that allows haemoglobin in blood to carry oxygen around body It could be the opening of a Jurassic Park rip-off: scientists examining ancient dinosaur bones find what appear to be fossilised red blood cells, and traces of the molecule that gives the beast’s blood its distinctive crimson hue. But that is what researchers are claiming to have discovered after analysing the hind leg bones of a small, meat-eating dinosaur called an Aratasaurus that lived and died in what is now north-eastern Brazil 115m years ago.
