Ancient Sandworm's Existence Extended by Millions of Years
Researchers have discovered fossils of a new species of predatory worm, similar to the sandworms in "Dune," that lived 480 million years ago, 25 million years after it was believed to have become extinct. These ancient Selkirkia worms, with rows of curved spines on their heads, were common predators during the Cambrian Explosion. The fossils were found in Morocco's Fezouata Formation, shedding light on the persistence of these formidable predators during the Early Ordovician period, a dynamic era of evolutionary transition.
