Human colonisation and vegetation response to Late Pleistocene to mid-Holocene climate variability in Northern Iberia based on a multiproxy analysis of the Atxurra cave-fill

Atxurra Cave (Berriatua, Northern Spain) contains an important Magdalenian archaeological assemblage comprising evidence of ephemeral occupation in the lower cave level and a unique assemblage of rock art. With the aim of understanding the palaeoenvironmental conditions and the nature of the human o...

With the aim of understanding the palaeoenvironmental conditions and the nature of the human occupation, detailed micromorphological, mineralogical, palynological and anthracological analyses were undertaken near the entrance of the cave. The lower part of the excavated sequence comprises almost unfossiliferous silty units deposited over a thick speleothem deposit, which alternates with a sandy-silt matrix-supported microfacies dated about 33.4 kyr B.P. Palynological assemblage in this unit suggest regional vegetation was formed by montane pines, junipers and broadleaved elements like birch and hazel. Overlying units of brown clayey material, dated to ca. 19.7–18.4 kyr B.P., contain evidence of a Gravettian occupation with Noailles burins, and a palynoflora indicative of localized conifers with a dense herbaceous steppe understory, in an arid and cold climate. At ca. 15.5–14.5 kyr B.P. there is a return to meso-thermophilous tree and shrub taxa within a warmer and humid climate background, which may have favored the regional development of the Magdalenian culture. The uppermost unit, dated ca. 7.7–7 kyr B.P., reveals postglacial expansion of a mixed Atlantic forest with no signals of anthropization before the start of the Neolithic.This research has been benefited from the financial support provided by DINAMO3 (CGL2015-69160-R), funded by the Spanish Inter-Ministry Commission of Science and Technology (CICYT). Archaeological research in Atxurra was funded by Bizkaiko Foru Aldundia between 2014 and 2015 for the excavation, between 2016 and 2020 for the rock art study, and by the Basque Government in 2014 for the analysis of archaeological material.Peer reviewedElsevierComisión Interministerial de Ciencia y Tecnología, CICYT (España)Diputación Foral de BizkaiaEusko JaurlaritzaMinisterio de Economía y Competitividad (España)Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202420242024info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Postprintinfo:eu-repo/semantics/acceptedVersionapplication/pdfhttp://hdl.handle.net/10261/354465reponame:DIGITAL.CSIC.
