Conus mamillaris
(Doderline, )
Possiede
una protoconca multispirale, planctotrofica (3) come il Conus
villalvernensis (Pavia et al., 2022)
del Pliocene, del quale potrebbe quindi facilmente essere il predecessore.

mm. 5,5 x 2,5 protoconca multispirale, Middle Miocene Conus sp. Plate 20 fig. 5 BkK-G815 (4) REMARKS, The only collected specimen is
a juvenile shell attributable to the subgenus Conolithus, but to
neither of the above described species . Its ornamentation on the edge of whorls
is different; the nodes on that edge are very similar to those in specimens
of Conus (Conolithus) antidiluvianus BRUGUIERE coming from the Vienna
Basin (see HORNES 1856, PI. 5, Figs 2a-2e), but the shells of the latter
species are featured apparently by a different width/height ratio (4). |
