Australian researchers chemically confirm dinosaur blood in 115-million-year-old fossil

Researchers from Curtin University in Australia chemically confirmed the presence of haemoglobin-derived molecules in a 115-million-year-old theropod leg bone from Brazil, delivering the first chemical proof of dinosaur blood. The team had earlier reported cell-like structures and heme molecules in the same fossil, describing them as mineralized red blood cells, while some experts voiced skepticism about the interpretation.
