Study offers glimpse of 500-million-year-old sea worm named after 'Dune' monster

Excavations by a University of Kansas paleontologist working in a treasure trove of fossils called the "Spence Shale Lagerstätte" have revealed an ancient sea worm unknown to science until now. The finding has now been published in the journal Historical Biology.
