Classification

Molecular data (Geiger & Thacker, 2005: Molluscan Research 25, 47-55) suggest that Scissurellidae are not monophyletic and that (Scissurella + Sukashitrochus) is the sister group to Lepetodriloidea in a crown clade with Haliotidae, and Anatoma is amongst the most basal Vetigastropoda including Pleurotomariidae. Anatomidae was treated at family rank by Geiger & Jansen (2004), and for lack of a better alternative, Bouchet & Rocroi (2005) have classified it as a family of Scissurelloidea. This was disputed by Kano (2008: Zoologica Scripta 37, 1-21) who does not believe that Anatomidae should be separated from Scissurellidae and suggests that this result was induced by contamination or mislabelling.

Anatomidae

Anatomidae is a family of minute sea snails, marine gastropod mollusks in the clade Vetigastropoda (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

Anatomidae was raised to the rank of family in a study by Geiger & Jansen (2004).[1] Bouchet & Rocroi placed it in the superfamily Scissurelloidea. This was disputed in 2008 by Yasunori Kano [2] who does not believe that Anatomidae should be separated from Scissurellidae and actually states that it is the subfamily Anatominae. He suggests that this result was induced by contamination or mislabelling. [3]

This family has no subfamilies.
