These ancient marine arthropods remain in fossil form only. Though they only remain as fossils, the marine creatures called trilobites filled the seas during the Paleozoic era. Today, these ancient arthropods are found in abundance in Cambrian rocks. The name trilobite comes from the Greek words tri meaning three, and lobita meaning lobed.The trilobites may have gone extinct (along with 95% of marine species) during the mass extinction at the end of the Permian period, but that doesn't mean that they were a failure. On the contrary, the trilobites survived for more than 250 million years (longer than the dinosaurs), and dominated seafloor ecosystems for much ofTrilobite fossils are dug by first, locating the fossil-bearing rock, and then splitting rock layers or breaking boulders to reveal the preserved trilobite carapace inside. Once the fossil is found, the pieces are reassembled and delicate preparation then ensues to remove the surrounding rock above and around the trilobite to expose the fossil for display.
