The molluscan fauna of the Kruisschans Member (Lilli Formation, Late Pliocene) in the Antwerp area (Belgium)

A list of all molluscan species recognised from the Kruisschans Member (Lillo Formation, Late Pliocene) as recently collected at Kallo and Antwerp (Belgium), is presented and commented upon. The molluscan fauna comprises 72 bivalve and 72 gastropod species, one of which is new ( Capulacmaea kalloensis sp. nov.) and nine of which have not been recorded previously from the Belgian Pliocene. The occurrence of Yoldia (Yoldia) myalis (Couthouy, 1838) and Admete viridula (Fabricius, 1780) marks the incoming of a cooler climate molluscan fauna, although warm climate species still survive, albeit in lesser numbers.
