The trilobites (or Trilobita) constitute a class of fossil marine arthropods having lived during the paleozoic one (primary era) of Cambrien to the Permian one. The last trilobites disappeared during the extinction of mass at the end from the Permian one, 250 millions years ago.

The trilobites are well-known because they are certainly the second groups most widespread of fossils after the dinosaurs. In addition, they gave the most diversified fossils: one counts between nine and fifteen thousand species. The majority of them were simple and small marine animals, which filtered the mud for eating
