It was assigned to Taras by Mukerjee (1939); to Veneroida by Sepkoski (2002); to Diplodontidae by Glenn (1904), Clark and Arnold (1923), Nagao (1928), Nagao (1928) and Bouchet et al. (2010); and to Ungulinidae by Marwick (1960), Adegoke (1977), Vokes (1980), Woodring (1982), Dockery (1982), Zinsmeister (1983), Ward and Blackwelder (1987), Moore (1988), Freneix et al.
