Rhynchonella


Rhynchonella is an extinct genus of brachiopod known from the Late Jurassic to the Early Cretaceous. Formerly this genus was understood much more widely and less critical sources still list species of Rhynchonella from the Ordovician to the Eocene. Like most brachiopods, Rhynchonella was a stationary epifaunal suspension feeder.

Description

These 1.75 to 3.75 cm-long articulate brachiopods are characterized by a triangular shell with a spherical profile, powerful ribs, a curved hinge line and a small umbo. The anterior margin shows a tongue like projection.
