Strophomenata is an extinct class of brachiopods in the subphylum Rhynchonelliformea.
They originated in the Cambrian period, hugely diversified during the Ordovician, and faced near extinction from the Permian-Triassic extinction. Only a few lingered around in the Triassic until eventually going extinct.[2] They were an exceptionally diverse group of brachiopods, and within the group the Strophomenids of the early Paleozoic and Productids of the late Paleozoic hugely contributed to the immense diversity.
