Belongs within: Rhynchonelliformea.
Contains: Productacea, Strophalosiacea, Chonetidae, Anopliidae.

The Productida are a group of brachiopods known from the Devonian to the Permian (possibly earliest Triassic). The pedicle was commonly absent (it is present only in some Chonetidina), and many productidans would have lived unattached to the substrate. In members of the suborder Productidina, the pedicle valve, and commonly the brachial valve, was provided with open tubular spines. Members of the Chonetidina commonly, though not always, had a spine row developed along the margin of the pedicle-valve interarea (Muir-Wood & Williams 1965).

Characters (from Brunton et al. 1995): Concavo-convex to planoconvex or conical corpus profile, commonly with trail; spines on ventral valve or both, rarely reduced to hinge regions or absent; dental plates absent; cardinal process bilobate, commonly protruding, with varied recessed myophores; brachial markings commonly present; mantle canals rarely marked; shell substance with crested or sheet laminae and pseudopunctate with taleolae.
