Olivella cf. longispira Bellardi, 1882

Fig. 7E–F

Olivella longispira Bellardi, 1882: 221 , pl. 12 fig. 37.

Olivella longispira – Ferrero Mortara et al. 1981: 133, pl. 35 fig. 3a–b.

Material examined

ITALY – Emilia-Romagna • 1 spec.; Guzzano ; MGGC 22311 (H = 11.8 mm) . – Tuscany • 1 spec.; Le Colline ; MSF 1202 (H = 13.4 mm) .

Remarks

Although the base of the aperture is not preserved in either of the two available specimens, they are here assigned to Olivella longispira due to their slender shells with a tall spire. This species was originally described from the Middle Miocene of the Turin hills, where it reaches 20 mm in height ( Bellardi 1882).

Stratigraphic and geographic range

Lower to Middle Miocene, northern Italy.
