The excavation of Manot Cave (Israel) reveals intensive occupation during the Early Upper Paleolithic and provides the first continuous set of anthracological data available for the Ahmarian, Levantine Aurignacian and post-Levantine Aurignacian periods. The paper aims to study the vegetal landscape around Manot Cave in the context of climate changes that characterized the last part of the Marine Isotope Stage 3 (MIS 3) and to address the issue of firewood and food procurement among Paleolithic hunter-gatherers. Charcoal samples recovered from the archaeological layers at Manot Cave shed light on the fuel and food procurement strategies while radiocarbon dating and stable carbon isotope analysis (ΔC) of selected charcoals provide information about the ancient climate. The results show that five woody taxa were exploited at the site; Amygdalus sp. was the most common species, whereas Quercus ithaburensis, Tamarix sp., Pomoideae indet., and Pistacia atlantica were relatively rare. The representations of the recovered wooden species suggest that an open forest of almonds and oaks existed in the area during MIS 3. Radiocarbon dating of Amygdalus sp. charcoals, coupled with stable carbon isotope analysis (ΔC) of modern and archaeological Amygdalus sp. clearly indicate variations in rainfall that could have decreased the density of tree cover. These analyses provide high-resolution data on the climate changes affecting the surroundings of Manot Cave between ∼46 and 28 ka cal BP and indicate two drier phases corresponding to the Ahmarian and post-Levantine Aurignacian cultures while a more humid period identified during the Levantine Aurignacian.
曼诺特洞穴(以色列)的挖掘揭示了其在旧石器时代晚期早期的密集居住情况,并提供了第一批可供研究的、关于阿马利亚时期、黎凡特奥瑞纳文化期和后黎凡特奥瑞纳文化期的连续炭化植物数据。本文旨在研究曼诺特洞穴周围的植被景观,以了解在海洋同位素阶段 3(MIS 3)末期影响气候的变化,并探讨旧石器时代的狩猎采集者的薪柴和食物获取问题。从曼诺特洞穴的考古层中回收的木炭样本为燃料和食物获取策略提供了线索,而放射性碳测年和选定木炭的稳定碳同位素分析(ΔC)则提供了有关古代气候的信息。结果表明,该遗址共利用了五种木本植物;杏仁属是最常见的物种,而柯属、柽柳属、未知李属和油橄榄属则相对较少。所回收的木本植物的代表表明,在 MIS 3 期间,该地区存在一个由杏仁和橡树组成的开阔森林。杏仁属的放射性碳测年,结合现代和考古杏仁属的稳定碳同位素分析(ΔC),清楚地表明了降雨量的变化,这可能降低了树木覆盖的密度。这些分析为曼诺特洞穴周围在约 46 到 28 千年前的气候变化提供了高分辨率的数据,并表明在阿马利亚时期和后黎凡特奥瑞纳文化期有两个较干燥的阶段,而在黎凡特奥瑞纳文化期则有一个更湿润的阶段。
