http://www.theguardian.com/science/2015/jun/09/75-million-year-old-dinosaur-blood-and-collagen-discovered-in-fossil-fragmentsScientists have discovered what appear to be red blood cells and collagen fibres in the fossilised remains of dinosaurs that lived 75 million years ago. Traces of the soft tissues were found by accident when researchers at Imperial College in London analysed eight rather shabby fossils that had been dug up in Canada a century ago before finding their way to the Natural History Museum in London. 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.
