Mactroidea

Mactra stultorum, copyright National Museum Wales.


Belongs within: Heterodonta.

The Mactroidea are a group of infaunal bivalves first recorded from the Upper Cretaceous. Members of the family Mactridae have the siphons united to their tips, whereas they are more or less separated in the Amphidesmatidae. Among major genera of the Mactridae, members of the genus Mactra have the shell ligament separated from the resilium by a shelly lamina (Cox et al. 1969).

Characters (from Cox et al. 1969): Thin-shelled, porcelaneous; hinge with inverted V-shaped cardinal tooth in left valve, two cardinals in right valve; lateral teeth and accessory cardinal laminae present in most groups; external ligament small or wanting, internal ligament or resilium seated in socket-like resilifer; pallial sinus normally well developed.
