These armored arthropods scuttled around seafloors for 270 million years before their extinction. They were present during the Cambrian but lived well into the Ordovician Period. WebTrilobites are a superphylum (Trilobitomorpha) of arthropods that are a hallmark fossil of not only the Cambrian, but also much of the Paleozoic. Many of the taxa of the Cambrian fauna, particularly the trilobites, were hit hard by the end-Ordovician mass extinction, and trilobites are one of many taxa that go extinct during the end-Permian mass extinction.
