The diagnostic feature for the order is the unique and complex dentition of the shell, (i.e. the interior hinge teeth that articulate the two valves). The dentition is particularly elaborate within the familyTrigoniidae.
Bieler, Carter, & Coan (2010) included the following families and superfamilies in Trigoniida.[1] Taxa marked with a † are extinct with the only extant family in the order being Trigoniidae.
