In Paleozoic seas, non-skeletal corals frequently grew on the bodies of marine animals called sea crinoids, or sea lilies--a flowery relative of the starfish. Though the seafloor is rich with their fossils, the pair seemed to disappear from the fossil record around 273 million years ago and was believed to have gone extinct.Pictured is an artist's illustration of Strigilodus tollesonae which translates to 'Tolleson's Scraper Tooth' Credit: National Park service The teeth were discovered …
