A 480-million-year-old fossil changes what we know about the origin of parasites

Ancient fossils unearthed in Morocco reveal parasitic worms burrowing into mollusc shells approximately 480 million years ago, pushing back the known timeline for parasitism by 60 million years. This discovery in the Fezouata Shale formation offers a remarkable glimpse into complex early marine ecosystems, showcasing sophisticated host-parasite interactions much earlier than previously believed.
