Opis

Diagnosis. - Apparatus composed of elements of approximately uniform size with smooth gradation of shapes, forming a single symmetry transition series (ne elements in advanced forms may be somewhat separated morphologically). Symmetrical elements, if present, of very generalized morphology.

Remarks. - The family differs from the Belodellidae and Panderodontidae in the lack of any prominent size gradient in the apparatus, and from the Protopanderodontidae in having only a single symmetry transition series in the apparatus and in the possible lack of unpaired tr element. The organization of the apparatus resembles closely that of members of the Panderodontida but careful phylogenetic studies are necessary to resolve the question of its relationships.

Genera included. - Cornuodus FAHRAEUS, 1966, Dapsilodus COOPER, 1976, Scabbardella ORCHARD,1980, Decoriconus COOPER, 1975, Besselodus ALDRIDGE, 1982, ?Strachanognathus RHODES,1955.
