Models of Neolithisation of Northeastern Iberian

Altres ajuts: The archaeological excavation at La Draga and Coves del Fem was funded by the Departament de Cultura (Generalitat de Catalunya) CLT009/18/00026 and CLT009/18/.The goal of this article is to discuss the significance of the archaeological evidence from the sites of La Draga (Banyoles, Spain) and Coves del Fem (Ulldemolins, Spain), in the context of the neolithisation of Northeastern Iberia. The 14C dates have been analysed using Bayesian statistics. The stratigraphy of Coves del Fem covers the transition between the last hunter-gatherers of the region and the first farmers. The chronological sequence covers approximately 1,300 years, from 6065-5990 cal BC to 4700-4550 cal BC. The site of La Draga was occupied by the first farmers circa 5300-5230 cal BC when a wooden platform was constructed and first used. Subsequent repairs of the wooden piles have been dated as well. Another use of the wooden platform is documented around 5200-5085 cal BC, although until now new construction evidence has not been documented. La Draga site was reoccupied later, when several travertine structures dated in two moments between the years 5100-4900 cal BC and 4950-4700 cal BC were constructed and used. The radiocarbon dates of Coves del Fem and La Draga support the existence of two different models of neolithisation in Northeastern Iberia. In the southern part of the territory, Coves del Fem suggests that the Holocene hunter-gatherer populations remained in the area until the arrival of the first farmers, in a model similar to the one observed at the Ebro basin. On the contrary, the site of La Draga supports the hypothesis of the first farmers colonising a previously unoccupied territory
