Fossilised Red Blood Cells Found in Dinosaur Bone
💡 Why it matters
Understanding dinosaur blood chemistry could unlock details about their metabolism, thermoregulation, and evolutionary links to modern birds and reptiles.
Scientists discovered fossilised red blood cells and traces of heme in the hind leg bones of a 115-million-year-old Aratasaurus dinosaur from Brazil. This marks the first identification of the organic compound that enables oxygen transport in dinosaur blood.
