In this paper remains of Daphnia found in the sediments retrieved from Lake Somaslampi (NW Finnish Lapland) and Lake Wigry (NE Poland) are presented and compared with Daphnia remains found by D.G. Frey in Greenland. Daphniapulex haedshields and shells were found in the early Holocene sediments of Lake Somaslampi. In the early Holocene sediments of Lake Wigry only postabdominal claws and ephippia of Daphnia were abundant, but in the sediments deposited during the last 50 years very well preserved shells of Daphnia longispina-group were found. The prezent findings indicate that the good preservation of Daphnia haedshields and shells may be more common than previously thought. It is possible that the special conditions they need to be preserved is cold climate.
