AbstractWe report new accelerator mass spectrometry radiocarbon (AMS 14C) dates of bones from humans, animals, and fish from grave 12 of the Lebyazhinka V Eneolithic burial ground in the middle Volga River region, Russia. Earlier conventional dates established a chronology. This has to be adjusted by new insights: the date has to be corrected for reservoir effects. For this purpose we redated bone from a human, and for herbivore and freshwater fauna from the same context, and included measurements of the stable isotopes δ13C and δ15N. The reservoir offset for the human appears to be about 700 14C yr.

AbstractThe regional component (∆R) of the marine reservoir effect (MRE), which is crucial for the accurate calibration of radiocarbon ages of marine-influenced samples, was determined for the Cuban northwestern coast. Fifteen different locations were studied by 14C dating of pre-bomb known-age marine shells specimens of bivalves and gastropods from the Felipe Poey Museum collection. Accelerator mass spectrometry (AMS) 14C measurements were performed at the Radiocarbon Laboratory of the Universidade Federal Fluminense (LAC-UFF) and mean ΔR values were estimated. The distribution of results indicates ∆R values from −46±38 to 140±52 14C yr and a possible pattern related to the position along the coast and ocean dynamics. We present both mean values for each region and a general ∆R of 28±13 14C yr for the northwestern coast of Cuba.

The Impact

The effect of natural fires on the vegetation cover of steppe and forest-steppe zones in the south-east of European Russia (the middle course of the Volga River) has been evaluated. The research used methods of studying biosystems at organism, species, population and cenotic levels. The study revealed the possibility of regrowth of aboveground plant parts after fires, changes in the population structure of species, and resistance of populations and zonal plant communities to the effects of natural fires. The most vulnerable among zonal vegetation types are pine forests, feather-grass and petrophytic steppes. Frequency, intensity and area of natural fires in the Middle Volga region cause significant changes in the structure of vegetation cover and reduction of biodiversity. The results obtained in the study of the impact of fires on vegetation can be used in the planning and implementation of environmental and reforestation measures.

Ams Dates

Twenty-three samples of charred food remains, charcoal, burned animals, and human bones from 14 Lithuanian prehistoric sites were dated by radiocarbon as part of a dating project oriented towards renewing the prehistoric ceramics chronology. The new dates modified the dating of ceramic styles by hundreds to a thousand years. Three Textile Ware sherds were dated to 4230–2920 cal BC—the oldest known dates of Textile Ware pottery in the East Baltic. The organic-tempered pointed-bottomed Narva and Combed-like Wares were dated to 3970–3370 cal BC, while Bay Coast Ware (Haffküstenkultur, Rzucewo), including vessels decorated with cord impressions, were dated to 3940–3540 cal BC, i.e. to a period well preceding the Corded Ware/Battle Axe horizon in Europe. Three dates of Globular Amphorae Ware placed the phenomenon directly beyond the Bay Coast chronology, i.e. in 3450–2920 cal BC. Chamotte-tempered Corded Ware from SE Lithuania was dated to 2840–2570 cal BC. The first absolute dating of coarse ware of the Žalioji type pointed to a period of 760–515 cal BC instead of the previously assumed 2nd millennium cal BC. Cremated human bones from urns found at Paveisininkai, Kernavė, and Naudvaris cemeteries were dated to 790–380 cal BC. Accelerator mass spectrometry (AMS) dates obtained from charred food remains should be treated with a certain caution due to a possible freshwater reservoir effect that has not yet been examined in Lithuania.

ABSTRACT The Nekselø Wickerwork provides an unusually solid estimate on the marine reservoir age in the Holocene. The basis for this result is a 5200-year-old fish weir, built of hazel wood with a brief biological age of its own. Oysters settled on this construction. They had lived only for a short number of years when the fence capsized and was covered in mud and the mollusks suffocated. Based on the difference in radiocarbon (14C) age between accelerator mass spectrometry (AMS) samples of oyster shells and wood, respectively, the marine reservoir age for this site is estimated to 273 ± 18 14C years. Re-evaluations of previously produced data from geological and archaeological sites of Holocene date in the Danish archipelago indicate marine reservoir ages in the same order as that of the Wickerwork. Consequently, we recommend the use of the new value, rather than the ca. 400 14C years hitherto favored, when correcting for the dietary induced reservoir effect in radiocarbon dates of humans and animals from the Late Mesolithic and Early Neolithic periods of this region.

The article deals with the problems of Neolithic chronology in the steppe and forest-steppe regions from the Volga to the Don. The main criterion of the transition to the Neolithic in the region should be considered the appearance of ceramic ware. In the southern region, the onset of the Neolithic was associated with indigenous processes in the period 7700-7200 years ago, with some influence from the Caucasus. In the northern territories, Neolitization occurred in 7500-7200 years ago and was influenced by the cultures of Central Asia. The early Neolithic on the border between the steppe and forest-steppe in the Volga river basin is represented by the Elshanka complexes with earthenware. The chronological ratio of the Neolithic of the southern and northern territories indicates the influence of steppe cultures on the development of the population in the forest-steppe of the Middle Volga region.

Shell Carbonate

The shell carbonate of pre- and post-bomb samples of 2 species of terrestrial gastropods (Theba pisana and Cernuella virgata) sampled along the coast of Apulia, southern Italy, were dated using accelerator mass spectrometry and carbon stable isotopes were analyzed. The analyses show, for both species, significant anomalies in the radiocarbon age due to the possible presence of a 14C-depleted source of carbon in the formation of the shell aragonite. The magnitude of the age anomaly was quantified in the studied area to ∼1000 14C yr.

This paper deals with the analysis of the materials from the Novoilyinskaya culture monuments in the Middle Kama River region, traces the issue history and determines how much is known about it. The main sources of the issue are given and their reliability is determined here. The location of the sites and the characteristic parameters of dwellings are recorded. Their similarity with the Neolithic is stated. The ceramic and stone tools are described. The characteristic and special features are distinguished. A comparative analysis of the complexes with the materials of the late Neolithic is carried out, that reveals a certain similarity. The paper considers the issue of the metalwork residues presence at the Novoilyinskaya culture monuments. It is concluded that there is no evidence of the Eneolithic character of the Novoilyinskaya culture sites. The database on radiocarbon chronology of the Novoilyinskaya culture complexes is analyzed. The most valid values are highlighted. Their chronological interval of existence is determined: 5200-4500 BP. The issue of the genesis of the Novoilyinskaya culture in the Middle Kama River region is covered. The proximity with the culture of the local Neolithic is stated, as well as the role of cultures of adjacent territories is assumed. A comparative analysis with materials of the Krasnomostovsky type of the forest Middle Volga region is given. The conclusion about their chronological correlation is made. The authors also come to the conclusion about the Post-Neolithic age of the Novoilyinskaya culture. This culture is included in the range of the forest Middle and Upper Volga region cultures.

Abstract —Eight dinocyst-based and three spore- and pollen-based biostratigraphic units are defined in the Kimmeridgian, Volgian, and Hauterivian of the Gorodishchi section, based on a biostratigraphic analysis of the successions of marine and terrestrial palynomorphs. Algological assemblages are described in more detail, and additional criteria for the definition of dinocyst zones established by previous researches are given. A more detailed biostratigraphic subdivision of the middle part of the Volgian is proposed. A local dinocyst zone in the Hauterivian and a biostratigraphic succession of spore–pollen units in the entire section are described for the first time. The research results demonstrate that the boundaries of many palynostratigraphic units exhibit a considerable correlation potential. Based on a biofacies analysis of the microphytoplankton, the dynamics of transgressive–regressive events is studied in relation to the accompanying oxygen and trophic conditions. Possible relationships between marine paleoenvironments and climatic changes reconstructed on the basis of spore–pol­len data are discussed.
