Material examined
ITALY – Tuscany • 2 specs; Ca’ Cavalmagra ; MSF 1312 , MSF 2364 .
Description
Low, turbiniform, smooth shell with about 2.5 whorls, about 3 mm across; whorls nearly circular in cross section, suture deep, slight bulge near upper suture.
Remarks
The two available specimens are embedded in rock matrix and are rather poorly preserved. They have the size and habitus of specimens belonging to the neomphaline Retiskenea (e.g., Warén & Bouchet 2001; Kiel 2006; Campbell et al. 2008; Kaim et al. 2014; Kaim 2022), but do not preserve details of the protoconch, which would be needed for a reliable assignment to the neomphalids. The specimens are quite similar to a ‘skeneimorph gastropod’ reported by us from the Late Miocene Ca’ Fornace seep deposit (Kiel et al. 2018).
Stratigraphic and geographic range
Middle Miocene (upper Langhian), northern Italy.
