Composita
brachiopod genus
Composita is an extinct brachiopod genus that lived from the Late Devonian to the Late Permian. Composita had a cosmopolitan global distribution, having lived on every continent except Antarctica. 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.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Composita”, the useful work is to connect “brachiopod genus” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Feb 2, 2026. The linked authority identifier is Q26149. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
