This superfamily dates back to the Paleozoic. They developed sinistrally (left-handed) or planispirally coiled teleoconchs.[2]

Taxonomy

Bouchet & Rocroi based their classification on the study by Bandel, published in 1993.[3] However, the position of the Porcelliidae is unsure, as noted by Peter J. Wagner in 2002. Wagner reported that the Porcelliidae belongs to the subfamily Gosseletininae, family Gosseletinidae, in the superfamily Eotomarioidea.

This superfamily consists of the four following families (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):
