Distribution
Rhynchonelloidella alemanica is known from the later Middle Jurassic (Bathonian) of England and Germany. The specimen that the description is based upon was collected in Fuller's Earth Rock, near Bath, Somerset, England (lectotype). Further specimens were collected from Weymouth, Bruton, Wiltshire, Gloucester, and Lamyat Beacon, Dyrham, Avon, Bristol Channel, Whatley, Somerset, and Sengenthal, Germany.
Habitat
During the Middle Jurassic, the fossil locations cited were on continental shelves, probably in tropical, shallow coral seas, where this lampshell lived as a stationary epifaunal suspension feeder.
