Fig. 7D

Material examined

ITALY – Tuscany • 1 spec.; Le Colline ; MSF 2359 (H = 19.6 mm) .

Description

Tall, slender shell, incised suture, at least three whorls, ten or more low, flat-topped spiral cords, earlier whorls with ca 10 broad, blunt axial ribs with wide interspaces.

Remarks

Shows the typical sculpture of Neptunea , but also of other buccinids including Buccinum or Beringius Dall, 1886 , or the high-spired species of Aulacofusus Dall, 1918 ( Kosyan & Kantor 2013). The only available specimen has a much higher spire than Eosipho hoernesi reported above.

Stratigraphic and geographic range

Middle Miocene (lower Serravallian), northern Italy.
