Opis:: Detailed geological and palaeobotanical study of about 400 boreholes through Quaternary deposits in eastern Belarus has enabled the recognition of a number of Middle and Late Pleistocene interglacial sites and demonstrated the stratigraphical position of Alexandrian (Holsteinian) and Muravian (Eemian) Interglacial sediments. These stratigraphic markers are separated by a single glacial sequence, corresponding to the Dnieper (Saalian) Glaciation. This contradicts previous views suggesting the occurrence of two glaciations during the Late Middle Pleistocene in eastern Belarus (Dnieper and Sozh). The glacial sediments represent the recession phases of a glacial stage that may be correlated with the Drenthe Substage of the Saalian Glaciation.

Opis:: Two new species of miniature owls are described from the upper Pleistocene asphalt deposits of Rancho La Brea, California. The first is assigned to the extant genus Glaucidium, as Glaucidium kurochkini sp. nov., and the second is placed in a new genus Asphaltoglaux, as Asphaltoglaux cecileae sp. nov. Both new species are based on tarsometatarsi, and each is represented by various elements. These are the second and third extinct owls to be described among the nine strigiform species from Rancho La Brea. The new species of Glaucidium is also recognized from the upper Pleistocene asphalt deposits of Carpinteria, California, which lends support to the hypothesis that southwestern coastal California was comparable to an island in the late Pleistocene. Recognition of these two new strigiform taxa brings to 22 the number of known extinct avian species from Rancho La Brea.

Opis:: Erosion network formed during the Mikulino-Valdai (Eem-Würm) Interglacial, which is now buried under recent deposits, is the best object of Quaternary geology. One can see its exposures in the Aleksandrov quarry on the Central Russian Upland. The Mikulino-Valdai erosion network certainly needs to be protected as a natural monument. Buried Mikulino balkas (wide flat-bottomed gullies) are unique natural objects, which represent a complete erosion cycle from the surface dissection to its stabilisation, palaeosol formation, and surface levelling as a result of denudation of watersheds and infilling or burying of depressions. On the basis of profiles studied along and across Mikulino balkas, it is possible to trace gradual and catastrophic changes of palaeolandscapes and reconstruct the development stages of topographical forms and soils, associated with climate change within the interglacial-glacial cycle. Over the balka bottom, one can observe the Valdai soil - lithogenic series having no analogues with such a precise and complete stratigraphy within the whole Russian Plain. Besides Mikulino Interglacial palaeosol, there are four buried soils of Valdai interstadial period: Kukuevka, Streletskaya, Aleksandrovka, and Bryansk palaeosols (33,140 š230 BP, Ki-8211). Such a complete set of Late Pleistocene palaeosols is very rare on the East European Plain. In the studied profile we have also found fragments of bones of furred rhinoceros and a prehistoric horse (39,710 š580, Ki-9362).

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 paleoecology of the South American fossil carnivores has not been as well studied as that of their northern relatives. One decade ago Fariña suggested that the fauna of Río Luján locality (Argentina, late Pleistocene–early Holocene) is not balanced because the metabolic requirements of the large carnivores are exceeded by the densities and biomass of the large herbivores. This conclusion is based on the calculation of densities using allometric functions between body mass and population abundance, and is a consequence of low carnivore richness versus high herbivore richness. In this paper we review the carnivore richness in the Lujanian of the Pampean Region, describe the paleoecology of these species including their probable prey choices, and review the available information on taphonomy, carnivore ecology, and macroecology to test the hypothesis of “imbalance” of the Río Luján fauna. The carnivore richness of the Río Luján fauna comprises five species: Smilodon populator, Panthera onca, Puma concolor, Arctotherium tarijense, and Dusicyon avus. Two other species are added when the whole Lujanian of the Buenos Aires province is included: Arctotherium bonariense and Canis nehringi. With the exception of D. avus and Arctotherium, these are hypercarnivores that could prey on large mammals (100–500 kg) and juveniles of megamammals (>1000 kg). S. populator could also hunt larger prey with body mass between 1000 and 2000 kg. The review of the “imbalance” hypothesis reveals contrary evidence and allows the proposal of alternative hypotheses. If high herbivore biomass occurred during the Lujanian, a higher density of carnivores could be supported than as inferred from the power function of body size and population density.

Opis:: During the Late Pleistocene, several possibly endemic cingulate species, known mostly from isolated osteoderms, carapace fragments, and caudal tubes, coexisted in the Brazilian Intertropical Region. Here, we describe the osteoderm microstructure of Pachyarmatherium brasiliense, as well as the glyptodonts Panochthus greslebini, Panochthus jaguaribensis and Glyptotherium sp., in order to provide additional species-diagnostic characters and shed light on their evolutionary relationships. Pachyarmatherium brasiliense lacks several derived features shared by glyptodonts and pampatheres, such as extensive bone remodeling, fibers arranged in large bundles, and relatively poorly developed layers of compact bone, thus supporting its exclusion from glyptodonts as suggested by a recent cladistic study. The osteoderm histology of P. greslebini resembles that of other species of Panochthus (e.g., Panochthus frenzelianus). By contrast, the presence of relatively thick layers of compact bone, the configuration and size of resorption areas, the absence of randomly oriented lateral fiber bundles, and the absence of an intermediary region between the compact and trabecular bone potentially support the exclusion of Panochthus jaguaribensis from the genus. Finally, osteoderms of the Brazilian specimens of Glyptodontinae share histological features with Glyptotherium floridanus, rather than Glyptodon, thus reinforcing their assignment to Glyptotherium. These results highlight the relevance of histological osteoderm characters in cingulate systematics, ands call for further and more comprehensive studies.

Opis:: Pleistocene camels from Mexico include representatives of llamas and camels. Their record spans from the Early Blancan to the Late Pleistocene, based on several localities in the northern, northwestern and central parts of the country, with members of the genus Hemiauchenia being particularly well represented. New specimens of a small llama, collected in the state of Hidalgo, central Mexico, are assigned to Hemiauchenia gracilis owing to a combination of cranial and postcranial characters, including a short upper premolar−molar series, the presence of a two−rooted P3, molars covered by a thin layer of cementum, U−shaped molar crescents, well−developed styles and ribs, a small degree of crenulation, a relatively short lower tooth row, the lack of p1 and p3, weakly developed anteroexternal stylids, a shallow and slender mandible, and long and slender metatarsals and phalanges. The material described here extends the Pleistocene geographic distribution of H. gracilisfrom northern to central Mexico, and its biochronological range from the Early Blancan to the Late Pleistocene (Rancholabrean), thus making it the southernmost record and the geochronologically youngest occurrence of this species in North America. The mesowear pattern of the material from Hidalgo suggests that these animals were mainly browsers. Their estimated body mass resembles that of Blancan specimens from Guanajuato, implying that this species maintained approximately the same body mass throughout its biochronological range in central Mexico.

Opis:: Loess-soil sequences provide one of the most continuous and detailed records of the climate changes on land areas in the Quaternary. The Late Pleistocene loess section in Dankowice (Niemcza-Strzelin Hills) is one of the best recognized in SW Poland. For the investigation of the chemical composition of loess-soil sequence in Dankowice, 31 loess samples were tested. Ten main oxides were determined (SiO2, Al2O3, Fe2O3, MnO, MgO, CaO, Na2O, K2O, TiO2 and P2O5) using certified reference materials to obtain good credibility of the analysis. The chemical composition of loess from Dankowice is similar to the results presented in the world loess literature. The characteristic feature is extremely high concentration of the silica. The chemical composition of loess in Dankowice is differentiated within the vertical sequence and confirm previous division of litho-pedostratigraphic units. Therefore, the chemostratigraphic method can be successfully used as a one of lithostratigraphic methods. Decreasing values of the chemical weathering indices to the top of the section may indicate that the source areas of loess silt have provided material over time, less and less transformed by prolonged and intense chemical weathering processes.

Opis:: The Tarnawce I profile, which occurs in the marginal eastern part of the Polish Westem Carpathians, contains loesses sq representing three last glacial cycles. In this paper we report the results of pollen analysis of the Eemian-Early Glacial pedocomplex and of the Lower plcni-Visrulian loesses with an interstadiał paleosol. The pollen spectra of22 samples were determined. The pollen diagram was divided into 7 local pollen assemblage zones (L PAZ). Interglacial climatic optimum was recorded with the Eemian type of vegetation in the T-4 zone. The coldest conditions occurred during the accumulation of loess, which separates the interglacial and interstadiał soils.

Tytuł:: Exceptional preservation of tracheal rings in a glyptodont mammal from the Late Pleistocene of Argentina

Opis:: Exceptionally well-preserved material from a fossil mammal is presented. For the first time, several fragments of tracheal rings and cricoid cartilage assigned to Panochthus sp. (Xenarthra; Glyptodontidae) from the Late Pleistocene of Argentina are described in detail and figured. In this contribution, in addition to a meticulous description, a tracheal ring was reconstructed and compared to tracheal rings of domestic and wild mammals. As a result, among domestic mammals it is similar to those of Sus scrofa domestica (domestic pig), and among wild mammals to those of Zalophus californianus (California sea lion). Tracheal rings of fossil vertebrates have been recognized in birds (Cariamiformes and Anseriformes) and other dinosaurs (Theropoda). This is likely the first report of tracheal rings in a fossil mammal; future comparisons with extant xenarthrans could provide information on the paleobiological implications of this structure in glyptodonts, and allow making inferences about other fossil mammals.
