Archaeogastropoda (also known as Aspidobranchiamollusks, mainly herbivores, typically having two gills and a double-chambered heart, with the eggs and sperm discharged directly into the water. They were traditionally regarded as a relatively primitive group.
This older classification of the gastropods is based on the classification of
paraphyletic
group, and therefore unacceptable in a strictly cladistic classification.
In the 1997 classification, most of the former Archaeogastropoda were included in:
- subclass Eogastropoda
- order Patellogastropoda (limpets)
- subclass Orthogastropoda
- Superorder Vetigastropoda Salvini-Plawen, 1989
- Superorder Neritaemorphi Koken, 1896 (with the order Neritopsina Cox & Knight, 1960).
A more detailed classification can be found on Gastropoda.
