Nucula aff. sulcata Bronn, 1831

Fig. 8A–D

Material examined

ITALY – Tuscany • 3 specs; Le Colline ; MSF 1210 (L = 6.2 mm), MSF 1212 (H = 7.3 mm), MSF 2366 • 1 spec.; same collection data as for preceding; NRM Mo 205366 • 1 spec.; Ca’ Cavalmagra ; MSF 1311 (L = 10.7 mm) .

Remarks

Nucula sulcata is an extant taxon, common in the European Neogene and Quaternary, its taxonomic history, nomenclature, and distribution was extensively discussed by La Perna (2007). The specimens illustrated here resemble Nucula sulcata in general outline, but with the hinge features obscured, our assignment remains tentative. Lucente & Taviani (2005) recorded a Nucula sp. of comparable dimensions (only a mold) associated with large vesicomyids from Serravallian-aged hydrocarbonimprinted sediments in the Romagna Apennines.
