- Short-term occupations at high elevation during the Middle Paleolithic at Kalavan 2 (Republic of Armenia)Publication . Malinsky-Buller, Ariel; Glauberman, Philip; Ollivier, Vincent; Lauer, Tobias; Timms, Rhys; Frahm, Ellery; Brittingham, Alexander; Triller, Benno; Kindler, Lutz; Knul, Monika V.; Krakovsky, Masha; Joannin, Sebastian; Hren, Michael T.; Bellier, Olivier; Clark, Alexander A.; Blockley, Simon P. E.; Arakelyan, Dimidry; Marreiros, João; Paixaco, Eduardo; Calandra, Ivan; Ghukasyan, Robert; Nora, David; Nir, Nadav; Adigyozalyan, Ani; Haydosyan, Hayk; Gasparyan, BorisThe Armenian highlands encompasses rugged and environmentally diverse landscapes and is characterized by a mosaic of distinct ecological niches and large temperature gradients. Strong seasonal fluctuations in resource availability along topographic gradients likely prompted Pleistocene hominin groups to adapt by adjusting their mobility strategies. However, the role that elevated landscapes played in hunter-gatherer settlement systems during the Late Pleistocene (Middle Palaeolithic [MP]) remains poorly understood. At 1640 m above sea level, the MP site of Kalavan 2 (Armenia) is ideally positioned for testing hypotheses involving elevation-dependent seasonal mobility and subsistence strategies. Renewed excavations at Kalavan 2 exposed three main occupation horizons and ten additional low densities lithic and faunal assemblages. The results provide a new chronological, stratigraphical, and paleoenvironmental framework for hominin behaviors between ca. 60 to 45 ka. The evidence presented suggests that the stratified occupations at Kalavan 2 locale were repeated ephemerally most likely related to hunting in a high-elevation within the mountainous steppe landscape.
- EcoPLis a pré-história no Rio Lis, da serra ao AtlânticoPublication . Pereira, Telmo; Carvalho, Vânia; Holliday, Trenton; Paixão, Eduardo; Monteiro, Patrícia; Évora, Marina; Marreiros, Joao; Assis, Sandra; Nora, David; Matias, Roxane; Simões, CarlosOur research focuses on the use of valleys that link the inland to the coast during Prehistory. Traditionally, research has studied rivers, coast and inland as separate landscapes, but the major characteristic of hunter-gatherers was mobility. In order to understand and reconstruct the evolution of human behaviour, our main goal is to answer the questions: “How, why and when did people circulate between these different ecological landscapes?” and “What was the impact of the major climatic shifts on that mobility?” To answer these questions our archaeological project includes survey, testing, and the excavation of archaeological sites, using high-resolution field and laboratory methodologies in order to contribute significantly to the understanding of ecological behaviour of Prehistoric populations, including extinct human species such as Neanderthals.
- Evidence of specialized resource exploitation by Modern Humans in Western Iberia associated to Pleistocene and Holocene extreme environmental conditionsPublication . Pereira, Telmo; Monteiro, Patrícia; Paixão, Eduardo; Nora, David; Évora, Marina; Simões, Carlos; Detry, Cleia; Assis, Sandra; Carvalho, Vânia; Holliday, TrentonThroughout prehistory, landscapes were repeatedly subjected to both global and localized climatic fluctuations that changed the regional environments where human groups lived. This instability demanded constant adap-tation and, as a result, the functionality of some sites changed over time. In this light, the western coast of Iberia represents an exceptional case study due to the proximity between at least some oceanic cores and archaeological sites, which should facilitate an accurate reconstruction of the re-lationships between paleoenvironmental conditions and the coeval patterns of human behavior. This region, and in particular the valley of the River Lis, is marked by wide exposed plateaus cut by narrow and deep canyons. In this paper we present the stratigraphic, archaeometric, technological and archaeobotanical record of Pogo Rock Shelter, located in one of these canyons, which hints at the human responses to such changes, and discuss the link between its Solutrean and Epipaleolithic occupations to specific activities. During the coldest part of the Last Glacial Maximum, we hypothesize that there was intensive exploitation of a chert outcrop above the roof to produce blades and Solutrean tips. Later, during Bond Event 6, after that outcrop had been exhausted, there was intensive consumption of shellfish gathered between the mouth of the canyon and the sea. We hypothesize that these strikingly different roles demonstrate how hunter-gatherers adapted to local conditions, and exploited specific resources, promising to provide a better understanding about its functional role during specific extreme climate events.
- Scales of toolstone transport in the Armenian Highlands during MIS 3: The contribution of Ararat-1 Cave (Ararat Depression) to reconstructing opportunities for social interactionsPublication . Frahm, Ellery; Cabrita Nora, David André; Gasparyan, Boris; Petrosyan, Artur; Malinsky-Buller, ArielMarine Isotope Stage (MIS) 3, ranging from around 57,000 to 29,000 years ago, is a period of significant archaeological interest due to notable transitions in lithic technology and hominin populations. In Europe, this time saw the replacement of Middle Palaeolithic (MP) technologies associated with Neanderthals by Upper Palaeolithic (UP) technologies linked to anatomically modern humans (AMHs). This technological shift is conventionally attributed to a demographic turnover; however, the timing of this transition varied regionally. The presence of Neanderthals and AMHs in the Levant, western Europe, and elsewhere over extended periods complicates the narrative, suggesting asynchronous and regionally diverse associations of hominin species and lithic technologies. This study shifts the attention to potential technological and cultural transmissions among MP- and UP-making groups, emphasizing the roles of social and exchange networks. Recent data from the obsidian-rich Armenian Highlands enable us to consider the mobility and land use of these groups without the added complication of toolstone with different knapping qualities, so patterns more clearly reflect mobility patterns, land use strategies, and potential social connections of foraging groups. These results suggest that, while MP-making groups in MIS 3 had overlapping territories, the UP-making groups at Aghitu-3 had smaller movements on the landscape. In contrast, MIS 2 sites with UP lithic assemblages have resource territories that apparently overlapped much like those of the MIS 3 MP sites. The findings hint at the possibility that differing mobility and land use during MIS 3 might have contributed to the coexistence of distinct lithic technologies, potentially through social transmission rather than a direct replacement of hominin populations.
