Trilobite phylum
Trilobites are one of the most popular fossils for collectors and are found all over the world. The Ute Indians used one species as an amulet, and there is even a cave in France called the Grotte du Trilobite that contained a relic made out of one of these extinct marine creatures.1,2 Trilobites are members of the phylum Arthropoda, which includes spiders, insects, and crustaceans.Calymene Brongniart, 1822, is a genus of trilobites in the order Phacopida, suborder Calymenina, that are found throughout North America, North Africa, and Europe in primarily Silurian outcrops. [2] Calymene is closely related to Flexicalymene, and both genera are frequently found enrolled. [3] Calymene trilobites are small, typically 2 cm in ...Cephalon (pl., cephala) – Anterior tagma composed in trilobites of a number of fused somites ( transverse division of arthropod body), applied by authors to anterior portion of exoskeleton separated from remainder of exoskeleton by an articulation (syn., cephalic region, head, head shield).
