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.
Related genera include Cariothyris and Planalvus along with Athyris.
