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.[1] Calymene is closely related to Flexicalymene, and both genera are frequently found enrolled.[2] Calymene trilobites are small, typically 2 cm in length. The cephalon is the widest part of the animal and the thorax usually has 13 segments.[3]

The correct genus authorship is Brongniart (1822).[4] A previously published genus description in Desmarest (1816)[5] (often mis-cited as "Calymena" Desmarest, 1817) was suppressed by ICZN Opinion 1433.

Etymology

Calymene - meaning beautiful crescent as a reference to the glabella.
