Aceste date arată că primii oamenii moderni din această regiune au inclus în dietă o gamă mai variată de animale, deşi datele arheologice şi morfologia funcţională a scheletelor umane din vestul şi estul Europei indică schimbări minore în exploatarea faunei pentru Paleoliticul mijlociu şi Paleoliticul superior vechi. Introduction Insight into the dietary spectra of Late Pleistocene humans, at least in Europe, is primarily based on the associated faunal remains, especially for assemblages in which the primary accumulating agent appears to have been humans, organic preservation is good, and the pestera dating has been sufficient to permit detailed zooarcheological analysis.

As a result, stable isotope analysis of human and faunal remains from the Late Pleistocene has been increasingly undertaken to provide pestera dating insight into Late Pleistocene human dietary spectra, especially for well-dated and in many cases, directly-dated human remains.

The Romanian human remains are, however, approached in time by the probably early Gravettian remains from Cro-Magnon and Paviland Henry-Gambier ; Jacobi and Higham The oldest of these remains, from the Peştera cu Oase Anina, Caraş-Severin at ~ 35 ka 14C BP, were water-transported surface finds within a karstic system that served primarily as a hibernation locale for large cave bear Ursus spelaeus with fossil and taphonomic evidence for some wolf Canis lupus activity Zilhão et al.

There are no archeological remains or other evidence of Pleistocene human activity within the cave system, and the human fossils appear to be secondary intrusions into the system. The isotopic data Table 1 derive from the direct 14C dating of the Oase 1 mandible Trinkaus et al.

Although there is evidence for an earlier Upper Paleolithic occupation of the adjacent Galeria Principală and especially Middle Paleolithic activity in both galleries, the site contains an abundance pestera dating U.

Given the use of the cave system as a carnivore den, partial excavation recovery of faunal remains, and uncertainties regarding the association of the human remains with specific archeological assemblages, the only dietary data available for the Muierii humans derives from their stable isotope values, also obtained as part of the 14C dating process.

The cranium was found during phosphate mining, and its original position in the cave is unknown.

Although Middle Paleolithic and Early Upper Paleolithic assemblages have been found in the cave Dobrescuthe cave served principally as a hibernation den for U. The human fossil is therefore without stratigraphic, paleontological or archeological context cf. Through a number of lines of research, including empirical observations and controlled experiments on living organisms, it has been determined that the carbon and nitrogen isotope ratios in mammal bone collagen reflect the isotope ratios of dietary protein consumed over the last years of the life of that mammal Wild et al.

There is variation between sites, and ideally one should pestera dating human δ15N values with respect to values from animals of known diet from the same levels of the same sites, something that is not always possible e.

Such 4. However, dietarily significant differences in δ15N values, given within population variation and within dietary category variation, should mitigate intersite variation in values. Carbon isotope ratios δ13C do not change, or change only pestera dating, between trophic levels, and they therefore reflect variation in plant carbon isotopes C3 versus C4 plants, with the former having lower or more negative δ13C valuesaccess to marine resources which have higher δ13C valuesand possibly climate van Klinken et al.

In Late Pleistocene Europe, C4 plants were not present, so δ13C variation should reflect minor paleoecological differences and, to some extent, access to marine resources Richards ; Pettitt et al.

Comparative Late Pleistocene human stable isotope values derive from published analyses of European late archaic Neandertal and early modern Early and Middle Upper Paleolithic humans, many of which were generated in the context of direct AMS radiocarbon dating of the human remains Table 2.

In cases in which specimens have been redated e. Variation in values from repeated measures of the same specimens and from different sample preparation protocols tend to be modest, close to ± 1.

Most of the human and faunal data derive from fully mature bone. However, four of the specimens are immature the Middle Upper Paleolithic Kostenki 4 and Sunghir 2 and 3 late juveniles and the Neandertal Engis 2 infant and one the Jonzac 1 Neandertal is a premolar root. In addition, among the comparative faunal remains, the Peştera Muieri A.

It appears that nursing immature individuals should be considered to be a trophic level higher than adults due to lactation. As a result, bone or dentin formed postnatally and prior to weaning may have δ15N values a few per mil higher than that of the mother, depending on the duration of nursing and the degree to which the diet of the infant is supplemented with other foods Jenkins et al. This should not pose a problem for the bone samples from the older juvenile Kostenki and Sunghir remains, nor for the Jonzac premolar given late juvenile root formation for human premolars Smith However, the Engis 2 δ15N pestera dating of Given the non-parametric pestera dating of the stable isotope distributions, sample comparisons are made using Wilcoxon P-values.

The Arene Candide 1 δ13C value, as well as the slightly lower Paviland 1 one, are apparently due to the consumption of significant amounts of maritime resources Richards ; Pettitt et al.

The addition of data from the earliest modern humans in Europe, now represented isotopically by those from Oase, Muierii and Cioclovina, as well as the undescribed Kostenki 8 specimen, extends any isotopic contrasts further back in the Upper Paleolithic.

At the same time, the available archeological and human paleontological evidence does not imply a major dietary difference between Neandertals and Early Upper Paleolithic modern humans. There is archeological evidence for improved weaponry in the Aurignacian Knecht, ; Liolios, ; Bolus and Conard,and similar evidence for effective spears is known from the Galeria 6.

In addition, functional analyses of the few known Early Upper Paleolithic human upper limb remains including the Muierii 1 scapula show little of the anatomical change associated with habitual spear throwing Trinkaus et al.

The Neandertal data derive from central and western Europe, whereas the Early Upper Paleolithic data are all eastern European Tables 1 and 2.

Yet, the Middle Upper Pestera dating human sample derives from sites across Europe, pestera dating the few herbivore and carnivore isotopic values for Peştera cu Oase and Peştera Muierii are similar to those for western European Late Pleistocene mammals. Rookiemag dating, more sampling of both Early Upper Paleolithic and preceding humans in diverse ecozones of Europe is pestera dating to resolve this isotopic contrast, in addition to zooarcheological data from across Europe and including species other than ungulates.

Conclusion The addition of carbon and nitrogen stable isotopic data for four Early Upper Paleolithic modern humans from Romania adds significantly to our dietary record for the European transitional period from Middle Paleolithic to Middle Upper Paleolithic and from Neandertals to early modern humans.

However, current archeological analyses suggest little dietary change from the Middle Paleolithic through the Early Upper Paleolithic, turning this isotopic insight into hypotheses to be, hopefully, tested against additional isotopic and faunal data.
