Classes

Aculifera (older name: Amphineura) is a proposed clade of molluscs incorporating those groups that have no conch or shell, that is, the Polyplacophora, Caudofoveata (=Chaetodermomorpha) and Solenogastres (=Neomeniomorpha).[1] It is sister to the Conchifera.

Two Ediacaran species, Korifogrammia and Clementechiton, which were found in the Clemente Formation in Mexico, may resemble stem-group Aculiferans.[2]
