Spatial and temporal disparities in human subsistence in the Neolithic Rhineland gateway

2020

International audience; The Alsace region bordering the Rhine River was extensively occupied during the Neolithic by farming societies with domesticated animal. The first settlers were two sub-groups of the Linearbandkeramik who appeared to diverge in several respects, including: pottery styles, house orientations and funerary rituals. To explore whether this was reflected in food procurement practices investigations were performed of organic residues in nearly 900 pottery vessels from sites across the region. The results reveal lipid biomarker and stable carbon evidence for exploitation of plant and bee products, and most significantly, extensive domestic animal products including: non-rum…

Microwear and isotopic analyses on cave bear remains from Toll Cave reveal both short-term and long-term dietary habits

2019

Dietary habits of the extinct Ursus spelaeus have always been a controversial topic in paleontological studies. In this work, we investigate carbon and nitrogen values in the bone collagen and dental microwear of U. spelaeus specimens recovered in Level 4 from Toll Cave (Moia, Catalonia, NE Iberian Peninsula). These remains have been dated to > 49,000 C-14 BP. The ability of both proxies to provide data on the diet of U. spelaeus at different times in the life-history (isotopes: average diet of life; microwear: last days/weeks before death), allows us to generate high-resolution and complementary data. Our results show lower values (delta C-13 & delta N-15) in cave bears than in strict herb…

The beginning of the Neolithic in Nerja cave and la Cova de la Sarsa. Archaeological context and radiocarbon dating

2018

Las dataciones radiocarbónicas resultan una herramienta útil para establecer el marco cronológicode los contextos arqueológicos, aunque en ocasiones el adjetivo de «absoluto» se convierte en una categoría. En el caso del Neolítico antiguo, la selección de muestras singulares de vida corta de especies domésticas o restos de Homo sapiens en contextos neolíticos pretendía definir con mayor precisión la cronología de los momentos iniciales de su llegada a la península ibérica. Los casos documentados en las cuevas de Nerja y Sarsa son un buen ejemplo del debate que generan sus resultados, la problemática de sus secuencias y el contexto de discusión regional. Se muestran los resultados tras la va…

Reconstruction of human subsistence and husbandry strategies from the Iberian Early Neolithic: A stable isotope approach

2018

Objectives The Early Neolithic involved an important social and economic shift that can be tested not only with the material culture, but also through biomolecular approaches. The Iberian Peninsula presents few Early Neolithic sites where fauna and humans can be analyzed together from an isotopic perspective. Here we present an isotopic study on the site of Cueva de Chaves as an example for understanding the dietary and economical changes that took place during Early Neolithic in Iberia. Material and methods Here we apply carbon and nitrogen stable isotope analysis to bone collagen from 4 humans and 64 faunal samples from 14 different species. The large dataset belongs to the same unique ch…
