Vegetation of the Ferdynandovian interglacial (MIS 13–15) based on plant macrofossils from a new profile of the stratotype site

Abstract

Early Middle Pleistocene palaeolacustrine sediments of the Ferdynandów site (E Poland), serving as a stratotype for the Ferdynandovian interglacial, were subjected to a new drilling in 2011. The obtained profile, covering the late Sanian 1 glaciation, two interglacial successions (Ferdynandovian 1 and 2), the cold Ferdynandovian 1/2 interval, and the early Sanian 2 glaciation, permitted a high-resolution plant macroremains analysis, correlated with the results of a palynological examination. In detailed studies of plant macroremains from the profile, new taxa were discovered for the Polish Pleistocene flora: specifically, species that are extinct or not found nowadays in Poland. On the basis of the taxonomic diversity and occurrence of bioindicators, the division into warm and cold units of the Ferdynandovian interglacial as well as units associated with the Sanian 1 and 2 glaciations, already applied in pollen studies, were confirmed, and the periods were described in terms of plant macroremains.
