"These bone-eating communities are ancient, and have been on Earth for at least 100 million years. Before #whales existed, bone-eating #worms were eating into the skeletons of #mosasaurs, #ichthyosaurs and #plesiosaurs... New research has named seven of these burrow types... some are very similar to the burrows of living #Osedax worms."
