Limopsoidea

 Cucullaea barbara, from Beu & Raine (2009).

Belongs within: Pteriomorphia.
Contains: Glycymeris, Tucetona, Limopsis, Hochstetteria, Lissarca.

The Limopsoidea are a group of bivalves that first appeared in the Lower Permian. Members of the family Glycymerididae are commonly known as ‘dog cockles’ in reference to their resemblance to the distantly related true cockles (Cardiidae). The shell is more or less equilateral in Glycymerididae but strongly inequilateral in Philobryidae; the Limopsidae include both equilateral and inequilateral species. Limopsidae have a short, unstriated ligament that is mainly restricted to the central triangular resilifer.
