    Rhynchonellata โ€“ Atlas of Ordovician Life

    WEBRhynchonellata is a class of brachiopods with a pedicle developed from a rudiment and various shell forms. Learn about its orders, characteristics, and published descriptions from the Atlas of Ordovician Life.

    What is a Rhynchonellata?
    The Rhynchonellata is a class of Lower Cambrian to Recent articulate brachiopods that combines orders from within the Rhynchonelliformea (Articulata revised) with well developed pedicle attachment. Shell forms vary from those with wide hinge lines to beaked forms with virtually no hinge line and from generally smooth to strongly plicate.

    Are Rhynchonellida plicate?
    Some, like the Rhynchonellida and Spiriferida, may be strongly plicate, with a median fold and sulcus. Others, like the Spiriferinida and Terebratulida are basically smooth. Most have shells without perforations known as punctae and are impunctate but some e.g. Orthida and Rhynchonellida have punctate offshoots.

    Are Rhynchonellata strophic shells or terebratulides?
    Among other features used in the suprafamilial classification of the rhynchonellata, the strophic shells of spriferides (s.l), thecideides, and some terebratulides were derived from astrophic stem groups and, therefore, separably taxonomically from those of orthides and protoorthides.

    How do rhynchonellides change during larval development?
    The rhynchonellides and related spire-bearing and loop-bearing orders are further characterized by the reversal of the mantle rudiment during larval development. This transformation is indicated on the shells by a forward shift of the attachment area of the ventral muscle field to make way for the pedicle capsule.
