Classification Established as an order containing the "Sippe" [= superfamilies] Zeugobranchia, Patellacea, Trochacea, Neritacea and Cocculinacea. Spelling emended to Archeogastropodida by Anderson (1992: 36).
Thiele (1925) included the three orders Archeogastropoda, Mesogastropoda, Neogastropoda in his concept of the subclass Prosobranchia, in a classification which has been a standard throughout the remainder of the XXth century and is still presented in current zoology textbooks (e.g. Brusca & Brusca, 2003). Currently the Archeogastropoda and Mesogastropoda are rebutted as paraphyletic, whereas Neogastropoda is considered a monophyletic group and therefore still accepted (as an order of the Caenogastropoda).
Extant families formerly included in the Archeogastropoda are now distributed in the subclasses Patellogastropoda, Vetigastropoda, Cocculiniformia and Neritimorpha, whereas some extinct families remain with an unresolved phylogenetic position (not asigned to a subclass) within the Gastropoda.
