Trilobites (scientific name: Trilobita) are an extinct class of marine arthropods. This is one of the oldest groups of arthropods, with the oldest recorded fossils dating from the Cambrian period (521 million years ago), and prospered throughout the Paleozoic era before the beginning of the Paleozoic era. At the beginning of a mass extinction, by the time of the Devonian period, all trilobite subgroups except the Proetida had disappeared. Trilobites died out in another mass extinction at the end
