Characters and relationships of the Mesozoic pelecypod Pseudavicula
£1.00
The hinge structure and the musculature are described and illustrated. An anterior ear and a sub-auricular notch are present in right valves, the ligament is of the 'pteriid' type with a chrondophore, and the musculature is similar to that of Chlamys. The main shell layer is composed of concentric interlocking lamellae and the valves although inequal are biconvex. It is concluded that Pseudavicula is a pectinoid and appears to be most closely related to forms placed in the subfamily Streblochondriinae of the family Aviculopectinidae.
