A publication within the journal Quaternary Worldwide led by Dr. Mathieu Duval, Ramon y Cajal Analysis Fellow on the Centro Nacional de Investigacion sobre la Evolucion Humana (CENIEH), relies on using an unprecedented mixture of three totally different relationship methods, specifically Electron Spin Resonance (ESR), Luminescence and Palaeomagnetism, so far two Decrease Palaeolithic websites in France.

“The preliminary function of this examine was to refine the chronology of those two websites, that are amongst the oldest proof of human presence in Western Europe, north of the 45°N latitude, earlier than 500,000 years in the past”, says Dr Duval. “They had been beforehand dated utilizing one methodology solely, and we now present an impartial age evaluation, based mostly on a multi-technique strategy that permits to construct a sturdy chronological framework.”
The 2 archaeological websites have delivered lithic instruments which are typical of the Decrease Palaeolithic, the oldest cultural interval recognized in Europe. The primary one, Lunery-la Terre-des-Sablons, offered an Oldowan lithic trade much like that discovered at different websites akin to Atapuerca Gran Dolina, Sima del Elefante, Barranco Leon or Fuente Nueva-3 (Spain).
Initially dated to about 1.1 million years, the brand new examine indicated a extra advanced website formation course of than thought earlier, and a minimal age of 710,000 years is now proposed for the lithic instruments. In distinction, the brand new age outcomes obtained for the second website, Brinay-la Noira, are in wonderful settlement with these obtained beforehand. They verify the age of the lithic trade to round 650,000 years, making the positioning one of many oldest Acheulean website in Western Europe.
“These days, the variety of outdated archaeological websites in Western Europe remains to be very restricted, which is why it important to acquire at the least an correct relationship for these which were discovered and excavated up to now. These new relationship outcomes will undoubtedly contribute to enhance our understanding of the timing of the early human settlements in Western Europe”, concludes Prof. Josep M. Pares, co-author of the work and Head of the Geochronology and Geology Programme at CENIEH.
This work is the results of a world scientific collaboration involving researchers from numerous prestigious establishments such because the CENIEH (Spain), Museum Nationwide d’Histoire Naturelle (France) and College of Adelaide (Australia).
