Family Palaeozygopleuridae Horný, 1955

Remarks. Since establishment of the family, its phylogenetic position has been unsettled (Horný 1955; Licharew 1970; Hoare & Sturgeon 1978; Hoare 1980; Batten 1985; Bandel 1991; Frýda & Bandel 1997; Nützel 1998; Blodgett et al. 1999; Frýda 1999; Frýda & Blodgett 2004; Frýda et al. 2008). They have been considered to be Archaeogastropoda, Caenogastropoda or Heterobranchia (see discussion below). The most discussed topic is their protoconch morphology and its interpretation (Frýda 2012). Here we follow the taxonomic position of the family Palaeozygopleuridae as presented by Bouchet et al. (2005).
