Dinosaur DNA may still be out of reach, but scientists are uncovering something almost as exciting—ancient blood vessels hidden inside fossilized bones. In a massive Tyrannosaurus rex nicknamed Scotty, researchers discovered a network of preserved vessels within a rib that once fractured and began healing 66 million years ago. Using powerful synchrotron X-rays from particle accelerators, they were able to peer inside the dense fossil without damaging it, revealing intricate, iron-rich structures left behind by the healing process.
