Content overview: “Fossilised Red Blood Cells Found in 115-Million-Year-Old Aratasaurus Bone in Brazil, Scien”. Scientists analysing a 115-million-year-old dinosaur bone from Brazil say they have found evidence of fossilised red blood cells and traces of heme, the compound that gives blood its red colour. The discovery, from the hind leg of a small carnivorous dinosaur called Aratasaurus, could reshape our un The discovery, from the hind leg of a small carnivorous dinosaur called Aratasaurus, could reshape our understanding of how soft tissues are preserved over geological time.
Researchers used chemical tests to identify the presence of heme, which is crucial for oxygen transport in living organisms. The findings suggest that organic molecules can survive for tens of millions of years under the right conditions. This has significant implications for palaeontology, as it opens the door to studying the biology of extinct species in unprecedented detail.
