Nov 2 : Scientists have discovered what they consider the strongest evidence yet of blood cells in a dinosaur fossil inside bone from the right leg of a medium-sized meat-eater that prowled Brazil some 115 million years ago during the Cretaceous Period.The researchers identified numerous microscopic structure

A dinosaur that breathed its last breath in the middle of the Cretaceous may have left behind more than a mould of its bones, with a study reporting the astonishing discovery of mineralized blood cells inside the theropod’s 115-million-year-old remains.

115-million-year-old fossilised red blood cells and heme biomolecules, proving that delicate organic structures can survive across deep geological time

The fossilized remains belong to Aratasaurus museunacionali, a species of coelurosaurian theropod dinosaur that lived in what is now northeastern Brazil during the Early Cretaceous epoch, some 115 million years ago.
