They lived as predators, filter feeders, deposit feeders, particle feeders, scavengers and even symbiotically.</p> <p>By looking at the functional morphology of the trilobite in question you can be more specific about how it lived, by looking at body shape, size, legs, eyes and other characters.</p> <h2>Advanced notes</h2> <p>Trilobites were very abundant during the Palaeozoic. Their preservation potential was increased further as they moulted their exoskeletons periodically as they grew. This means that one trilobite left numerous hard skeletons or partial skeletons as it grew, each of which has the potential to fossilise.</p> <h2>Specimens</h2> <p><a href="/p1acollections/exhibits/show/trilobites" target="_blank" rel="noreferrer noopener">Browse trilobites</a></p> <h2>Links</h2> <p><a href="https://www.digitalatlasofancientlife.org/learn/nature-fossil-record/types-of-fossil-preservation/">Learn about types of preservation</a></p> https://wserv3.esc.cam.ac.uk/p1acollections/files/original/c6b9427325c8a625a1fb715e2ba9b761.png b6c4554bb25cbd01fe2923d72ebaa959 https://wserv3.esc.cam.ac.uk/p1acollections/files/original/852990c0fa5efed6ff5d4c9668161751.png 826993442acd7add97b325580bd69a2c Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.
