This superfamily was previously included in the Caenogastropoda by Ponder and Warén (1988) and by Bandel in studies published in 1993 and 1997. However, studies by Tracey et al. (1993) and by Frýda and Manda (1997) put them into the Archaeogastropoda. This has been confirmed by new findings on archaeopod-type protoconchs in species from this families, dating from the early Devonian.
