Composita is an extinct brachiopod genus that lived from the Late Devonian to the Late Permian.[1] Composita had a cosmopolitan global distribution, having lived on every continent except Antarctica.[1][2] Composita had a smooth shell with a more or less distinct fold and sulcus and a round opening for the pedicle on the pedicle valve. Composita is included in the family Athyrididae (Order Athyridida) and placed in the subfamily Spirigerellinae.
