Kostenki 14 is part of the Kostenki-Borshevo site complex on the Don river (Figure above), one of the more important Upper Palaeolithic site-complexes of Europe. The deposits at Kostenki 14 have provided rich archaeological assemblages and important palaeoclimatological/-environmental datasets. It is located close to the sites Kostenki 16 and Kostenki 5. Based on previous fieldwork at Kostenki 14, the Early Upper Palaeolithic (EUP) sequence (e.g., Sinitsyn, 2004, 2010; Haesaerts et al., 2004; Holliday et al., 2007; Pietsch et al. 2014; Sedov et al., 2010; Velichko et al., 2009) includes at the base the cultural layer IVb that has been dated to 37/36 ka uncal BP and cannot be attributed to any known EUP industry. Above and separated from layer IVb by sterile deposits, two layers with undiagnostic lithic artefacts are known (dated to 34.5 and 33 ka uncal BP), the Layer in the Fossil Soil and the Layer IVa. Above and associated with lenses of volcanic ash the Aurignacian layer (Layer in the ash), including personal ornaments, is reported. Associated charcoals provided ages of 32.4 ka uncal BP. For the younger part of the sequence, which is not of primary interest for the current project, see, e.g., Sinitsyn (2004, 2010), Velichko et al. (2009) and Haesaerts et al. (2004).

On of the more interesting aspects of the Kostenki 14 sequence is the fact that the EUP deposits encompass two external stratigraphic markers: (1) a volcanic ash layer (with the Aurignacian assemblage) attributed to the Campanian Ignimbrite (CI) eruption, and (2) the Laschamp palaeomagnetic excursion (LPE) (e.g., Sinitsyn, 2004; Haesaerts et al., 2004; Holliday et al., 2007; Velichko et al., 2009). Both markers are of crucial importance for the current discussions of the chronostratigraphic position of the EUP throughout Eurasia. With potential limitations of radiocarbon dates due to unsuccessful removal of contaminants and hence underestimations of the true age of the samples the identification of the CI ash and the LPE offers independent chronostratigraphic marker horizons. Equally important is a detailed description of the deposits and the sedimentary dynamics, one of the key objectives for the current project's work besides radiocarbon dating, in order to understand the formation of the deposits and post depositional alterations. 

Kostenki 14 is also known for one of the oldest modern human burials in Europe - providing us with one of the first modern human fossils in Europe. The skeleton was discovered during excavations in the 20th century (Sinitsyn 2004; Seguin-Orlando et al, 2014).

The NEMO-ADAP project team's work at Kostenki includes the following work:

 

* Stratigraphy, Sedimentary Dynamics and Chronostratigraphy:

NEMO-ADAP project team members Paul Haesaerts and Stéphane Pirson are analyzing the stratigraphy, sedimentary dynamics and chronostratigraphy of the long sequence at Kostenki 14, eastern trench. Kostenki 14, eastern trench, is excavated by a team around Andrei Sinitsyn since the 1990s.

Figure compiled after Sinitsyn (1996) and Haesaerts et al. (2004). 

 

Fieldwork includes analysis of sections and sampling for cryptotephra and soil micromorphology analysis. Analysis of the section includes a detailed section drawing and micro-stratigraphic analysis as well as a study of the sedimentary dynamics to understand the formation of the deposits.

In the last years, the NEMO-ADAP team has been studying the ash deposits related to the Campagnian Ignimbrite (CI/Y5) eruption about 40,000 years ago. Our team’s work focuses on the formation of the ash layer, its re-working through various processes. A better understanding of the degree of re-working is essential for the use of CI/Y5 ash deposits at Kostenki 14 as a chronostratigraphic marker horizon. We are also re-assessing the location of the ‘Aurignacian Layer in the ash’, an archaeological horizon located below, within and above the ash in order to resolve its age and chronostratigraphic position.

Preliminary results of our work were presented at the UISPP conference in Burgos/Spain in September 2014 by NEMO-ADAP team member Paul Haesaerts.

* New chronology for the Early Upper Palaeolithic:

We are collecting and selecting charcoal samples for radiocarbon dating (AMS) the Early Upper Palaeolithic occupation of the Kostenki-Borshevo region. Selected sites include Kostenki 1, 12 and 14. Our results for the Streletskian layers at Kostenki 1 and 12 suggest older ages for these layers than previously thought. 

Our preliminary results were presented at the ESHE meeting in Vienna/Austria in September 2013.

* Contribution to the study of the genome of the Kostenki 14 burial and implications for the population history of Upper Pleistocene Europe:

NEMO-ADAP project team contributed to the analysis (Seguin-Orlando et al. Science 2014) of the genome of more than 36,000 year-old skeleton from the site Kostenki 14. The skeleton originated from a burial and was excavated in the 1950s. 

The genome reveals an early divergence of Eurasians once they had left Africa, and allows scientists to better assess the point at which ‘admixture’ - or interbreeding - between Eurasians and Neanderthals occurred. The latest research also points to a previously unknown population lineage as old as the first population separations since humans dispersed out of Africa.

The researchers, led by Eske Willerslev from the Centre for GeoGenetics at the University of Copenhagen, recovered and sequenced the complete genome of a man who was buried about 37,000 years ago at the site of Kostenki 14 (also known as Markina Gora) in western Russia. The study provides unique insights into the history of the continent. The genome shows that once modern humans had dispersed out of Africa and into Eurasia, they separated at least before 37,000-years ago into at least three populations, whose descendants would develop the unique features that reflect the core of the diversity of non-African modern humans.

Since then, despite major climatic fluctuations, one of these groups - Palaeolithic Europeans - persisted as a population, ebbing and flowing by moments of contraction and expansion, but persisting intertwined until the arrival of farmers from the Middle East in the last 8,000 years, with whom they mixed extensively. The Kostenki and other ancient genomes show that for 30,000-years there was a single meta-population in Europe, consisting of Palaeolithic hunter-gatherer groups that split up, mixed, dispersed and changed. Only when farmers from the Near East arrived approximately 8,000 years ago, did the structure of the European population change significantly.

 

The study also shows that, as with all living Eurasians, the Kostenki 14 man's genome included a small percentage of Neanderthal genes. While this confirms earlier findings, the current study revealed that the Kostenki 14 individual had a slightly higher percentage of Neanderthal genes than ever observed before. Further, the genetic fragments that this individual inherited from a Neanderthal ancestor are larger, i.e. not yet broken by the thousands of recombination events that have occurred since. This allowed the team of scientists to estimate the time of human-Neanderthal admixture to 54,000 years ago.
