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

Researchers from Curtin University in Australia chemically confirmed dinosaur blood by detecting haemoglobin-derived molecules in a Brazilian theropod leg bone. Earlier, the team had reported cell-like structures and heme molecules in the same fossil, suggesting preservation of blood components for over 100 million years, though some experts expressed skepticism. The recent confirmation builds on those initial observations, providing the first direct chemical proof that dinosaur blood can survive in fossilized form.
