Brachiopoda : Lingulidae

LINGULIDAE


Sous-embranchement (subphylum) des Linguliformea Classe des Lingulata Ordre des Lingulida Super-famille des Linguloidea

Famille LINGULIDAE Menke, 1828
[nom. correct. Gray, 1840, p. 155, pro Lingulaceae Menke, 1828, p. 56, nom. imperf.] Shell elongate oval to subrectangular, gently and subequally biconvex, subequivalved; lateral margins generally subparallel. Ventral valve with wide triangular pedicle groove and lateral vestigial propareas. Dorsal valve with posterior margin rounded, with a more or less developed median beak; anterior adductor and anterior oblique muscle scars closely spaced. Asymmetrical muscle system with internal oblique muscles; unpaired posterior adductor muscle; pedicle nerve curving around posterior adductor muscle. Mantle canal system bifurcate; vascula lateralia of both valves converging anteriorly to become subparallel; vascula media absent. Long flexible pedicle; lophophore spirolophous, with apices of spires directed medially. Diagnosis from Emig (2003) Middle Ordovician - Present
