Turbonilla sp.

Fig. 7J

Material examined

ITALY – Tuscany • 1 spec.; Ca’ Cavalmagra; MSF 1305 (H = 2.3 mm) .

Description

Tall slender shell made of at least six whorls sculptured by indistinct, blunt, slightly oblique axial ribs.

Remarks

This specimen resembles species of Turbonilla reported from the Neogene of northern Italy ( Sacco 1892). Quite similar is the Late Miocene Turbonilla costellatoides var. dertocolligens Sacco, 1892 , but our specimen is too poorly preserved for a species-level identification.
