Flemingella bistriata ( Münster, 1841)

Fig. 12D .

1841 Trochus bistriatus n. sp.; Münster 1841: 108, pl. 11: 16.

1891 Flemmingia bistriata ; Kittl 1891: 253, pl. 7: 14–16.

1992 Flemmingia bistriata ; Bandel 1992: 47, pl. 4: 4, 5.

Material.—One shell ( PZO 12713) from the Misurina Landslide surface sample, Italy, Carnian, Triassic.

Remarks.—This shell that is about 8 mm high, closely resembles the specimens illustrated by Kittl (1891) and Bandel (1992). There are several other Cassian species that have been assigned to Flemmingia . Flemmingia bicarinata (Klipstein, 1843) as reported by Kittl (1891) is very similar to our specimen. However, this species has been considered a synonym of Flemmingia bistriata by Bandel (1992).

Stratigraphic and geographic range.—Only known from the Carnian, Upper Triassic; northern Italy (Cassian Formation).
