The present is a palaeobiological and taphonomic analysis of a Marine Isotope Stages (MIS) 4–3 (Late Pleistocene) assemblage of animal remains and hominin artefacts from layers 7–5 of Biśnik Cave, Czestochowa Upland, Poland. The analysis indicates that the bone assemblage is the result of a time-averaged palimpsest of both biotic and episodic abiotic events, the former consisting of many successive generations of animals and hominins that frequented the cave, and the latter including hydraulic winnowing. In fact, the taphonomic history of the fossil assemblage from Biśnik Cave's layers 7–5 is partially obscured by the overprint of hydraulic winnowing, which purportedly removed a certain amount of the original specimens. Besides evidence of cave bear deaths from non-violent, hibernation-related mortality and of occupation by generations of denning wolves and hyaenas, there is a wealth of flint artefacts, alongside remains of a few fireplaces and of a structure built in the cave by hominins to partition the cave chambers. The studied layer contains an impressive number of shed antlers, primarily of the red deer Cervus elaphus. Crocuta crocuta spelaea is normally held responsible for such accumulations of shed antlers in various European caves; Biśnik Cave's layers 7–5 will therefore simply add to the list. However, the role of accumulator of shed antlers attributed to the Pleistocene spotted hyena does not match the behaviour of its modern counterpart and seems not accounted for metabolically. The only reasonable alternative is that the antlers were collected by hominins. From this alternative perspective the cave would have functioned as a warehouse, where naturally shed antlers were stored as raw material, potentially to be shaped into tools and/or employed as tools to make other tools. The palaeobiological and taphonomic analysis presented here provides new insights into the succession of pre- and postdepositional events that involved the bone remains accumulated in the cave, as well as into the interactions between the animals and hominins of the time. More importantly, if hominins, and not hyaenas, were responsible for the amassment of the shed antlers in Biśnik Cave, this study raises doubts as to the hyaenid or human origin of other similar cave accumulations of shed antlers throughout Europe.

We present a description of an almost complete skeleton of the forest rhino (Stephanorhinus kirchbergensis) found near Gorzów Wielkopolski (Northwest Poland) in its geological and palaeoenvironmental context. While finds of bones and teeth are common, the importance of this find resides in, that it is the most complete specimen of this species, almost perfectly preserved in a well-studied and dated stratigraphic and sedimentological context, along with other fossil fauna and flora. The OSL dates of glaciofluvial sediments sandwiching skeleton-bearing horizons indicate a Middle Eemian age of the Pleistocene paleolake land. This warm climate is also indicated by the results of sedimentological, geochemical, paleobotanical, and isotopic analyses. The rhino skeleton was deposited in a shallow area near the lake’s littoral zone. Bite marks of a large predator (cave hyena) were recognized on the rhino’s pelvis, which, due to their location, were probably created post-mortem. With an estimated height of 1.82 m at the withers, this was a large adult Stephanorhinus kirchbergensis. The results of osteometric analyses indicate that we are dealing with one of the largest known individuals of this species. Although it suffered from a pathologically deformed spine, the individual died at a relatively old age.

Panthera spelaea was recorded in Poland from 18 open-air and 42 cave sites dated in the range 750–28 ka. Most of these records are located in southern Poland (Silesia) and neighbouring areas. Among them, the find of Panthera spelaea in Kozi Grzbiet mentioned here for the first time is one of the oldest European records of the species. Most of the obtained AMS dates are concentrated on the second half of MIS 3 and showed that the Pleistocene lion disappeared more or less synchronously across Poland. The findings of its remains from open-air sites are mostly accidental discoveries during field works, while those in caves are mostly connected with archaeological research and the exploitation of cave sediments for producing fertilizers. Aside of a few juvenile bones and milk teeth, the remains of adult individuals, mostly males, predominate in the studied sample. Their behavior to hunting cave bear during the times, when the other, more typical food sources were scarce, tendention to hunt very big preys and went into the conflicts with other carnivores than females do, resulted in higher injuries and mortalities. Within the species, three chronosubspecies were recognized, with P. s. fossilis recorded from 7 sites, dated between 750 and 240 ka and P. s. intermedia only partially recognized in Wierzchowska Gorna Cave. The most numerous are the remains of P. s. spelaea which were found in 48 localities dated between 150 and 28 ka. With the exception of four caves, the Polish finds of P. spelaea are generally less abundant at sites where they occur. Older P. s. fossilis, dated on MIS 19–12, was a large form with robust stature and broad cheek teeth. Younger P. s. fossilis dated on MIS 11–9 was represented by a large and massive specimens, but with more advanced morphological dental features. Polish individuals of P. s. spelaea were slightly smaller and less massive than P. s. fossilis, with narrower cheek teeth. Since MIS 3, a dwarf and gracile specimens appeared, which is correlated with the genetic turnover ca. 48–45 ka. The Pleistocene lion was one of the earliest disappeared large carnivores predated only by a cave hyena. There are no direct evidences of P. spelaea encounters with humans. The extinction of P. spelaea is broadly correlated with the general collapse of the “mammoth steppe” ecosystem and was resulted of multiple reasons like climatic changes, re-building of herbivore guilds, competition and human pressure. Wolf and, to a lesser extent, bears were the main competitors for the Pleistocene lion in Poland.

Subfossil remains of the Quaternary megafauna from two Ukrainian natural history collections stored at Kaniv Nature Reserve and the National Museum of Natural History NAS of Ukraine were examined. Most of the bones were collected in 1965–1966, in the building pit and the gateway of the Kaniv hydroelectric power plant. The fauna is represented at least by ten taxa (Gulo gulo, Mammuthus trogonterii chosaricus, Mammuthus intermedius, Coelodonta antiquitatis, Megaloceros giganteus, Alces alces, Bison priscus, Cervus elaphus, Capra cf. ibex, and Equus ferus). Skeletal parts are represented mainly by skulls, long bones, horns, and tusks. Based on the species composition of proboscideans, at least part of the faunal assemblage is dated by the end of the Middle Pleistocene (Dnieper Stage = Saale, Warta, MIS 6), but majority of bones could be older or younger (Late Pleistocene and Holocene age) due to the alluvial origin of accumulation.

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 sequences of mtDNA cytochrome b, including 194 ancient and 75 contemporary samples newly obtained for this study. The inclusion of 161 radiocarbon-dated samples enabled us to study the phylogeny in a temporal context and conduct divergence-time estimation and molecular dating. Depending on methodology, our estimate of divergence between Cervus elaphus and Cervus canadensis varied considerably (370 000 or 1.37 million years BP, respectively). The divergence times of genetic lineages and haplogroups corresponded to large environmental changes associated with stadials and interstadials of the Late Pleistocene. Due to the climatic oscillations, the distribution of C. elaphus and C. canadensis fluctuated in north–south and east–west directions. Some haplotypes dated to pre-Last Glacial Maximum periods were not detected afterwards, representing possibly extinct populations. We indicated with a high probability the presence of red deer sensu lato in south-eastern Europe and western Asia during the Last Glacial Maximum.

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 reconstruct the fauna composition, but also to highlight the environmental conditions that dominated at this locality. A revision of the fauna of Medzhybizh 1 locality based on remains of all vertebrate groups revealed a taxonomically diverse fish community (16 species of 11 genera) dominated by cyprinids common for lacustrine or riverine assemblages. Amphibians are represented by 11 species, while the number of reptile and bird remains are less significant. Mammals are the most represented group at the locality, including small mammals (30 species), carnivorans (2 species), and ungulates (5 taxa), the latter dominated by C. elaphus. The taxonomic composition of terrestrial groups indicates temperate climate with boreal-type forests and meadows similar to cold steppe, as well as low wet areas and riparian habitats inhabited by amphibians, reptiles, insectivores, beavers, and various voles. The fish assemblage indicates a partially overgrown but well-aerated water body (lake or slow-flowing river) with sandy-silty bottom. Lithic artefacts found at the Medzhybizh 1 locality contribute to a better understanding of relationships between ancient hominins and faunas during the Middle Pleistocene of Eastern Europe., Archaeological field works at Medzhybizh were supported by the NASU state research projects 0105U001383 (2005–2009), 0109U008921 (2010–2014) and partly funded by the State Fund of Fundamental Research of Ukraine grant 0118U001457 (F77/50–2018).
