Ampezzopleura bandeli Nützel, 1998

Fig. 17H .

Material.— Twenty four specimens, 21 from bulk samples, 3 from surface samples; all from Misurina Landslide ( PZO 12703 , 1 figured specimen; PZO 12702 , 23 specimens); Italy, Carnian , Triassic .

Remarks.—The illustrated specimen ( Fig. 17H ) from Misurina Landslide is deformed over its entire shell length (shell 1.6 mm high; protoconch about 0.3 mm high). It has preserved its small, bulbous larval shell that is typical of that species ( Nützel 1998).
