Forget Jurassic Park's experts and Ross Geller off Friends, Dr Mary Schweitzer is one real-life paleontologist with some rather interesting information to share. Her fascinating research resulted in the discovery of soft tissue and red blood cells in the fossilised bones of a 68-million-year-old T-Rex. Sure that's like something you'd hear on Isla Sorna... Mary's work has totally transformed the way scientists look at dinosaurs, and she believes that she may also have found traces of the creatures' DNA.
