Fragmented bivalve (mainly Mya truncata) and Balanus shells were collected at 21-35 m a.s.l. from terminal/marginal moraine, and at 46-65 m a.s.l. from morainic dirt cones and eskers at Werenskioldbreen, south Spitsbergen. They yielded radiocarbon ages of 26,600 š 1400 years B.P. (Late Pleistocene = Vistulian Glaciation), and 10,660 š 220 - 10.500 š 160 years B.P. (Pleistocene/Holocene transition: Younger Dryas/Preboreal), respectively. In 1974, the source marine deposit, probably shell-bearing clays, was hidden under glacier ice. Formation of this deposit could be simultaneous with raised marine abrasion terraces at 36-40 m and 24-32 m a.s.l., respectively.
