Early Valdai carpological assemblages from the Upper Volga Region

Results of modern carpological studies of the Ples section in the Upper Volga Region are discussed. The section includes sediments of the Mikulino (Eemian) Interglacial and Early Valdai (Early Weichselian) Glacial. Particular attention is given to Early Valdai carpological assemblages. The analysis of their composition and comparison with palynological data from the locality and carpological data from western regions of the East European Plain allows one to assign the assemblages under study to two relatively warm episodes of interstade type. For the first time, the carpological characteristics of two warm episodes are given for this territory.
