Order
Terebratulida
Terebratulids are one of only three living orders of articulate brachiopods, the others being the Rhynchonellida and the Thecideida. Craniida and Lingulida include living brachiopods, but are inarticulates. The name, Terebratula, may be derived from the Latin “terebra”, meaning “hole-borer”. The perceived resemblance of terebratulid shells to ancient Roman oil lamps gave the brachiopods their common name “lamp shell”.
