Ancient Tapeworm Eggs Found in Fossilized Shark Poop news.yahoo.com Scientists now reveal they found a spiral-shaped coprolite from a shark that holds a cluster of 93 oval tapeworm eggs. One of them even contains a probable developing larva, which held a cluster of fiberlike objects that may have been the beginnings of hooklets used to attach to a host's intestines as adults. [See Photos of the Parasite Eggs & Fossil Poop] The fossils, unearthed in southern Brazil, date to the Paleozoic era (251 million to 542 million years ago), before dinosaurs roamed the Earth. This predates other known examples of intestinal parasites in vertebrates by 140 million years.
