A new sedimentary morphogenic analysis was carried out at the Divje babe I Paleolithic site to determine paleotemperatures for Late Pleistocene deposits (around 80,000–40,000 BP) and to discover hiatuses in the sedimentary sequence. The Divje babe I paleotemperature record is based on the relative abundance of congelifracts in a 280 cm thick sedimentary sequence. Congelifracts are clasts whose morphogenesis is directly associated with post-depositional frost wedging. The Divje babe I paleotemperature record compares well with global GRIP (Summit) and other regional paleotemperature records for the Late Pleistocene. Comparisons are supported by ESR dates from the Divje babe I site. Two significantly cool climate phases were identified in the Divje babe I record. The older cool phase was placed between 67,000 BP and 62,000 BP and the second, younger cool phase was placed between 61,000 BP and 58,000 BP (both Middle Würmian) according to correlations with the GRIP record. The main disadvantage with the Divje babe I paleotemperature record is missing data. The sequence of cave sediments is not complete in Divje babe I due to breaks in sedimentation. Two reliable and two assumed hiatuses were identified in the studied sedimentary sequence.  相似文献

The pre-Neolithic history of the Tibetan Plateau is virtually unknown. Test excavations of Late Paleolithic sites, described here, provide preliminary evidence that the initial occupation of the plateau's extreme environments was by small groups of foragers probably traveling from lower elevation plateau margins. These foragers occupied very short-term camps focused on the procurement and extensive processing of small-to-medium mammals. Five separate occupations date to 13–15,000 Cal yr BP, but limited survey data suggest mid-elevation locations may have been temporarily occupied as early as 25,000 years ago. Full-time, year-round occupation of the plateau probably did not take place until the early Neolithic advent of domesticated animals.  相似文献

To understand major processes of human evolution during the Plio- Pleistocene, it is necessary to consider the available evidence from key regions of the Old World. The Arabian peninsula is often depicted as a key geographic route for hominin dispersals in Out of Africa models, although the available primary evidence is rarely cited. And yet, significant Lower Paleolithic assemblages have been identified in many parts of the peninsula, including in areas near the Strait of Bab al Mandab. The presence of Oldowan-like and Acheulean assemblages may reflect at least two major dispersals outside of Africa. Acheulean localities are particularly abundant on the Arabian peninsula, and variations in stone tool manufacturing techniques and tool-type frequencies may reflect temporal changes in assemblages. Although there is good potential to chronometrically date sites in the Arabian peninsula, absolute dating methods have not been adequately applied, most temporal reconstructions relying on typotechnological change. If the Arabian peninsula is to provide solid evidence for understanding hominin adaptation and dispersal patterns, future fieldwork in secure depositional contexts needs to be conducted to overcome current limits in dating and environmental reconstructions.  相似文献

In spite of an active and sophisticated archaeological research program, the Paleolithic of the Iberian peninsula remains comparatively little known to English-speaking prehistorians, with the exception of Cantabrian Spain. The rich data set compiled by Spanish prehistorians and their colleagues over the past several decades stands to make a valuable and unique contribution to our understanding of the Pleistocene prehistory of Europe. We present a detailed overview of Upper Paleolithic chronology, sites, and assemblages for Mediterranean Spain, an area of over 1,600,000 km 2 that extends from the French border to the Straits of Gibraltar. To interpret these data, we employ a regional perspective that emphasizes studies of paleoeconomy (especially zooarchaeology) and settlement. The Middle–Upper Paleolithic transition and Upper Paleolithic art also receive detailed treatment, and the Upper Paleolithic of Mediterranean Spain is discussed in the broader context of the late Upper Pleistocene of western Europe and the Mediterranean Basin.  相似文献

This study conducted petrographic and geochemical analyses of chert artifacts from the Late Middle Paleolithic, the Initial Upper Paleolithic, the Early Upper Paleolithic, and the Epi-Paleolithic assemblages in the Jebel Qalkha area, southern Jordan, to examine their correlations with the visual attributes and diachronic variability. The results revealed two different aspects of the petrographic and geochemical signatures. The first aspect showed some correlations with the visual chert types that were characterized by the abundance/preservation of fossils, the enrichment of several elements (i.e., Ca, Sr, and Ba), and the quartz crystallite size. The second aspect of geochemical signatures, such as Fe, Mn, Ni, Cr, and Co, showed no correlation with the visual types but was correlated with the chrono-cultural groups. Given the chert occurrences and variability in and around the study area, the first aspect of the chert variability likely represents the variations of different chert outcrops as well as the internal variations within the same sources. Whether the second aspect represents chrono-cultural changes in the use of chert sources needs to be clarified in future by our ongoing examination of geological chert samples in the study area.  相似文献
