Rhynchonella is an extinct genus of brachiopod known from the Late Jurassic (Oxfordian) to the Early Cretaceous (Valanginian, possibly Barremian).

[1] Formerly[2] this genus was understood much more widely (more or less an equivalent of the Rhynchonellida order in the present-day taxonomy) 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.

[3] 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.
