Pterothecidae is an extinct family of Paleozoic molluscs of uncertain position, either Gastropoda or Monoplacophora, with isostrophically coiled shells.


The taxonomy of the Gastropoda by Bouchet & Rocroi, 2005[2] categorizes Pterothecidae in the superfamilia Bellerophontoidea within the Paleozoic molluscs of uncertain systematic position with isostrophically coiled shells (Gastropoda or Monoplacophora).

This family consists of the following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):

  • Pterothecinae P. Fischer, 1883
  • Carinaropsinae Ulrich & Scofiled, 1897
  • Pedasiolinae Wahlman, 1992
