Rhynchonella
Extinct genus of brachiopod
From Wikipedia, the free encyclopedia
Rhynchonella is an extinct genus of brachiopods 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]
