See text Murchisonioidea is an extinct superfamily of small to large sea snails, marine gastropod mollusks in the clade Vetigastropoda.
[1] 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)[2] and by Frýda and Manda (1997)[3] 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.
