It was assigned to Mollusca by Sepkoski (2002); to Bivalvia by Nevesskaja (2009); to Euprotobranchia by Carter et al. (2011); and to Rostroconchia by Peel (2021).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. S. Peel 2021 | Pseudobivalved (univalve) or bivalved laterally compressed Dshaped shells with a long straight dorsal hinge zone and convex ventral margin. Hinge zone in pseudobivalved forms is flexible with a prominent, raised, undivided early growth stage along the median plane of symmetry and a variable numbers of hinge teeth. Bivalved forms are equivalve, with taxodont dentition consisting of a number of oblique, subparallel, barlike teeth forming two elements on each valve that are separated by a narrow, erect, amphidetic ligament. Inner shell surface formed of foliated calcite. |
