Terebratulida
Sign in to saveTerebratulids 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".

Pygites diphyoides (d'Orbigny, 1849) de l'Hauterivià (Cretaci) de Cehegin, Múrcia. Coenothyris oweni de l'Anisià a Israel. Els Terebratúlids (Terebratulida) són un dels tres únics ordres que encara viuen de braquiòpodes articulats els altres ordres són els Rhynchonellida i els Thecideida. Craniida i Lingulida inclouen braquípodes que encara viuen,però són inarticulats. El nom, Terebratula, potser deriva del llatí "terebra", que significa "perforador". Els Terebratúlids típicament tenen conquilles biconvexes que normalment són ovoides a circulars en la línia exterior. Els Terebratúlids poden haver evolucionat a partir dels Atrypida durant el Silurià.

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".
Terebratulids typically have biconvex shells that are usually ovoid to circular in outline. They can be either smooth or have radial ribbing. The lophophore support is loop shaped in contrast to the spiralia of similar looking spiriferids. Terebratulids are also distinguished by a very short hinge line, and the shell is punctate in microstructure. There is a circular pedicle opening, or foramen, located in the beak.
