Opis:
In 2005, numerous vertebrate tracks were discovered in carbonate aeolianites in and around the town of Paphos, in the south western part of Cyprus. The main track-bearing exposure is located in a protected archaeological site near the Agia Solomoni Church in side the city of Paphos, where cross-sec tions through tracks are abundant in vertical exposures of the aeolianite along Apostolou Pavlou Avenue. Some exposures show as many as 10 tracks per m2 of vertical exposure. Several additional tracks were found in the extensive subterranean tomb complex, the Tombs of the Kings, just outside Paphos. The aeolian deposit was formed when westerly to southwesterly windsdrove fine- to medium-grained calcareous sand onshore from the beach. This generated low coastal dunes, represented by 1–2-m-thick, cross-bedded sets made up of grainflow and wind-ripple strata, and sand sheets composed entirely of wind-ripple strata. The sediment does not yet have an absolute date, but is considered to be of Late Pleistocene to Early Holocene age, as are many other coastal aeolianites in the Mediterranean area. The Late Pleistocene endemic fauna in Cyprus was limited to the dwarf hippopotamus Phanourios minor Desmarest, 1822, the dwarf elephant Elephas cypriotes Bate, 1902, a small carnivore Genetta plesictoides Bate, 1903, and (possibly) humans. The exposed tracks are 5–15 cm in diameter, with a few tracks up to 23 cm in size. This range of size correlates well with the estimated foot size of dwarf hippopotami and dwarf elephants. This low-diversity, endemic is land fauna provides a unique opportunity to correlate tracks with trackmakers.

Opis:
The paper deals with the morphometric analysis of remains of the reindeer Rangifer tarandus Linnaeus, 1758 from 20 Late Pleistocene cave localities in Poland. In most of the localities, the species was the most abundant component of the large mammal fauna; the remains came from individuals, killed by predators, including man. The measurements of the remains were compared with those of reindeer from localities in Germany, Moldova, Ukraine and Russia. The measurements of the reindeer from Poland were intermediate between the smaller and more slender reindeer from north-western Europe and the larger reindeer from southern and eastern Europe; the antlers from the localities studied mainly represented the tundra form of Rangifer tarandus. The forest form of the species was represented by a few antlers. With respect to the ages of individuals, the reindeer from the Polish sites belonged to the age classes of under 2 years, 5–6 years and 6–7 years.

Opis:
The paper deals with remains of the elks Cervalces latifrons, Cervalces sp. and Alces alces from Middle and Late Pleistocene sites in Poland. A form of the genus Cervalces occurred in Poland from the early (Kozi Grzbiet, MIS 19–17) to the late Middle Pleistocene (Biśnik Cave, MIS 6 or MIS 5e). The genus Alces appeared in Poland in the Eemian Interglacial (Dziadowa Skała Cave). Compared to the other cervids, elk remains from Poland are very few, but they mark important faunal changes. Kozi Grzbiet and Sitkówka are virtually the only Polish localities from the lower part of the Middle Pleistocene with the remains of large mammals, and the only records of Cervalces latifrons. The specimens from Biśnik Cave are among the last records of the occurrence of Cervalces in Europe. During the Last Glacial Maximum, elks were absent. Though the elks were the least abundant cervids, they were present at sites from milder climatic regimes (interglacials and interstadials) till the Holocene. Elk remains of that period are single teeth and postcranial skeletal bones from the beginning of glaciation in the deposits of Łokietka Cave (MIS 5a–d), Interplenivistulian (MIS 3): caves Biśnik and Obłazowa) and Borsuka Cave (MIS 3–2). In the Late Vistulian (MIS 1, Allerød and Younger Dryas), the elk recolonized the area occupied by Poland.

Opis:
This paper presents the results of absolute dating and biostratigraphical analysis carried out for alluvial sediments of an abandoned Starunia ozokerite mine located in the Velyky Lukavets River valley, in which large mammal remains were discovered in the first half of the 20th century. The sediments build up three terrace levels. The highest one, up to 8 m high (terrace II), is likely to be associated with a stage of aggradation, as well as with a short episode of valley broadening, which occurred in the Weichselian Late Pleniglacial. The lower one, 4 m high (terrace I), is most likely to be linked with the Holocene, despite a considerable transformation of its top due to mining activity. The lower part of this terrace cover bears coarse-grained channel sediments dated to 120.6-58.9 ka BP (Eemian Interglacial?-Early Pleniglacial - OIS 5e, 4 and 3), and overbank (distal floodplain) mud with intercalations of biogenic deposits (peat, peat mud and biogenic mud). The overbank deposits are dated to 48.2-11.11 ka BP (Glinde Interstadial?-Younger Dryas, OIS 3-2) and are overlain by Holocene (OIS 1) mud and biogenic deposits. In boreholes drilled in the vicinity of the present-day river channel, younger sediments occur more frequently. These include sediments originating from the Late Weichselian overlain by Holocene sediments. However, sediments originating exclusively from the Holocene are infrequent. The deposition of sediments took place in specific conditions of a permanent saturation of the environment with brine, petroleum and thickened bitumen. In the longest period of deposition (48.2-1.27 ka BP), ephemeral swamps, ponds and lakes were developed in different parts of the floodplain. They were marked by the presence of: Juncus glaucus/effusus, J. articulatus, Typha sp., Batrachium sp., Potamogeton filliformis, Bidens tripartita, Ranunculus sceleratus and Phragmites communis, as well as by halophytic species, like: Zannichellia palustris, Triglochin maritimum, Schoenoplectus tabernemontani, Puccinelia distans and Eleocharis palustris. Rhythmic oscillations between cold and warm climatic conditions, typical of the Weichselian age and well identified in Western Europe, are here marked by the changes of plant communities (woody assemblages passing into steppe and tundra), but are not noticeably recorded in the sediments of the Velyky Lukavets River. This shows that the greatest part of the discussed period involved the formation of poorly differentiated silty overbank sediments with intercalations of biogenic sediments. However, the variability of sediments provides evidence for extreme events which occurred in the Holocene.

Opis:
The sub-Quaternary topography of the western Sandomierz Basin has been compared to variable thicknesses of Quaternary sediments and geomorphology of the area. The lithology and age of the top of Miocene strata have been determined. The Witów Series has been interpreted as a sequence of a braided river that used to flow into the retreating marine basin, forming a fan delta whose age, according to macrofloristic determinations, has been assigned to the Late Miocene. Lower Quaternary gravels cap the remnants of a planated surface situated at 240-250 m a.s.l. The Błonie gravel horizon occurring at a similar altitude was deposited by a river active in Narevian and/or Nidanian glacial stages, and its top underwent reworking during the Sanian-2 stage. Deposits infilling the fossil sub-Carpathian Furrow have been mapped and dated to the Cromerian s.l. interglacial stage. The final alluviation of this segment of the furrow took place during the Sanian-2 stage. Reconstruction of the drainage pattern during the Eopleistocene, South-Polish glaciations, and Masovian inter- glacial stage has been proposed as well.
