The raised bog sediments that have been continuously accumulated over time represent the most suitable natural object which enables us to reconstruct Late Glacial and Holocene vegetation and palaeoclimates. Bog peat consists of organic carbon formed in situ. It contains moss, plant fragments and microfossils that are necessary for the study of palaeovegetation and palaeoclimate. However, a successful study of palaeoenvironment can be carried out on the basis of investigation of a great quan-tity of samples along the whole peatbog thickness. In the present paper, the authors present the results of palynological, botanical investigations and radiocarbon dating of 31 peat samples taken from the raised bog Velikoye, located in the eastern part of Kaliningrad Region. The data obtained have ena-bled us to reconstruct the palaeovegetation, reveal the evolution of the bog and determine rate of peat formation at different evolutional stages over the last 7500 cal BP.

During the last years the investigations of Stone Age and Early Metal sites on the Karelian Isthmus were much intensified. Presently, about 180 archaeological sites belonging to these periods are recorded. A considerable part of these sites have been found and investigated by joint cooperative efforts of Russian and Finnish archaeologists. 12 sites of Mesolithic, Neolithic and Early Metal ages are characterized by 30 radiocarbon dates. Several dates were obtained from the sites of prolonged duration and with a mixed stratigraphy, which makes them less reliable. This article includes the catalogue of 14C dates and the information regarding their attribution.
