What happens to giant marine animals, like whales, when they die and sink? Well once the soft parts have been scavenged, you might imagine the bones would remain and the sea floor would be littered with skeletons. However, these bones provide a potential resource and life always evolves to exploit an opportunity. Introducing the Zombie worm, or Osedax if you want their proper name. These worms bore into bones and extract the lipids and fats. Well, new fossil discoveries by Silvia Danise and Nick Higgs show that these worms have been doing this for at least 100 million years. By examining the bones of marine reptiles from the Cretaceous they have identified the tell-tale markings of Osedax. Where did the authors find these remarkable fossils? In a museum's collection of course. Even if it is in a museum, a fossil can still have a myriad of secrets to reveal.
