All trilobites were mobile and most seem to have crawled on the sea bed. A small number of species became burrowers or active swimmers. Most extremely, some trilobites became pelagic, with a permanently swimming, active lifestyle above the sea bed. These forms had eyes with up to 360° vision and a streamlined body.Trilobite relatives Trilobites belong to the Artiopoda, a group of extinct arthropods morphologically similar to trilobites, though only the trilobites had mineralised exoskeletons. Thus other artiopodans are typically only found in exceptionally preserved deposits, mostly during the Cambrian period.

Thus other artiopodans are typically only found in exceptionally preserved deposits, mostly during the Cambrian period.While a few were wide-ranging pelagic species, most were regional, and their global paleogeography is a fascinating study of how living forms track their changing environments over geological time. Trilobites from different habitats often had specialized forms that were presumably adaptations to their environment.Trilobites were a hugely successful group and they are the most diverse group recorded in the fossil record, but the last fossil trilobites are found in rocks which are 250 million years old. Trilobites have become one of the most studied groups of extinct animals and their evolution is well documented in the fossil record.

Trilobites are the most diverse group of extinct animals preserved in the fossil record. Ten orders of trilobites are recognized, into which 20,000+ species are placed. Learn more about trilobite morphology , anatomy , ecology , behavior, reproduction , and development , and how they relate to trilobite origins , evolution , and classification . Trilobites were among the most successful creatures ever to exist on earth. Their march through evolutionary time began back in the Lower Cambrian, some 521 million years ago, and lasted for nearly 270 million years, until the end of the Permian, 252 million years ago. By the end of the Cambrian Period several groups of invertebrates were well established in shallow marine environments, perhaps most notably were trilobites, brachiopods, crinoids, bryozoans, sponges, and gastropods (snails) are locally common fossils preserved in Cambrian sedimentary rocks (Figures 2-24 and 2-25).…
