Patinigera magellanica, photographed by Jan Delsing.

Belongs within: Gastropoda.
Contains: Patella, Scutellastra, Acmaeidae, Lepetidae, Lottiidae, Cellana.

The Patellogastropoda, true limpets, are a group of marine gastropods with cap-like shells bearing a horseshoe-shaped muscle attachment, and a docoglossate radula with few claw-like teeth in each row. Though generally believed to occupy a basal position in gastropod phylogeny, patellogastropods have a poor fossil record, probably due to most species occupying high-energy environments not conducive to preservation.
