Pectinodontidae is a family of sea snails or true limpets, marine gastropod mollusks in the clade Patellogastropoda, the true limpets.

Taxonomy

This family was previously ranked as subfamily Pectinodontinae (also with Acmaeinae and Rhodopetalinae) in the family Acmeaidae in the taxonomy of the Gastropoda by Bouchet & Rocroi (2005).

Nakano & Ozawa (2007)[2] elevated Pectinodontinae to family level Pectinodontidae based on molecular phylogeny research.[2]

Genera in the family Pectinodontidae include:

Pectinodonta - the earliest known Pectinodonta are from Late Oligocene[3]
