Productida

The Devonian Devonochonetes coronatus, from here.


Belongs within: Rhynchonelliformea.

The Productida are a group of brachiopods known from the Devonian to the Permian (possibly earliest Triassic).

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.
