Strophomenata is an extinct class of brachiopods in the subphylum Rhynchonelliformea.

Orders[]

An order that contains the suborder Clitambonitidina (and others?) .

An order or superfamily that includes the Chilidiopsoidea.^[2] Ontogeny given by Bassett and Popov (2017), resembling that of Kutorginides.^[2]

Believed to be sister to Strophomenides, = Strophomenida + Billinsellida + Productida.^[3]

Includes the Chileids (e.g. Coolinia).
