General The name trilobite means three lobes, the body consists of three parts or lobes. If we look at the trilobite from top to bottom, we can see the head, then the thorax and finally the tail.
Trilobites molt several times during their life cycle, so most trilobite fossils found are actually molts.
Trilobites are a class of marine animals that became extinct 250 million years ago (Paleozoic). There were over fifteen thousand species of trilobites.
