Jurassic Park around the corner? 75-million-year-old dinosaur blood and collagen discovered in fossil fragments

Red blood cells and collagen fibres in the fossilised remains of dinosaurs that lived 75 million years ago.

The finding suggests that scores of dinosaur fossils in museums around the world could retain soft tissues, and with it the answers to major questions about dinosaur physiology and evolution. More speculatively, it has made scientists ponder whether dinosaur DNA might also survive.
