Article
The Middle Pleistocene was a period of dynamic changes in Europe. During MIS 11, a number of modern mammal taxa appeared and environmental conditions remained warm and favourable for a relatively long time. The Medzhybizh 1 locality of Ukraine dated to this very period comprises alluvial deposits with rich animal remains, which allow not only to re...
Article
Remains of the steppe bison Bison priscus Bojanus, 1827 from the Upper Pleistocene layers of Biśnik Cave were morphometrically analysed and compared to those from other localities in Eurasia. The remains occurred in accumulations with archaeological artefacts. They bore traces of gnawing by carnivores. Morphometric analyses of the skull and post-cr...

Records of decapod taxa reported from Oligocene and Early Miocene fish beds of the Central and Eastern Paratethys have been reviewed in order to discuss taphonomic features at selected localities. In total, 120 specimens originating from 30 localities in Azerbaijan, the Czech Republic, and Ukraine were studied. The identified crab taxa include majo...
Article
The present phylogeographic pattern of red deer in Eurasia is not only a result of the contraction of their distribution range into glacial refugia and postglacial expansion, but probably also an effect of replacement of some red deer s.l. mtDNA lineages by others during the last 50 000 years. To better recognize this process, we analysed 501 seque...

Robust chronologies are crucial for the correct interpretation of climate proxy records and for detailed reconstructions of palaeoclimate. Stalagmites have garnered strong interest as recorders of past climate in part due to their amenability to U-series dating. However, many stalagmites are not dateable using this technique due to low 238U and/or...
