Barranco Leon（Guadix-Baza Basin，西班牙东南部）的早更新世遗址，可追溯到1.4 Ma（数百万年前），记录了西欧最古老的人类活动，这一点可以通过发现一颗牙齿和数千件模式1石器来证明。本文详细分析了该地点D1和D2单元的微脊椎动物含量。早更新世在Guadix-Baza盆地的特点是急剧的气候恶化，这可能阻碍了早期人类人口从南高加索地区的解决。不久之后，当气候条件再次有利时，在巴兰科莱昂的D1和D2单元突然证明了人类的存在。根据对这些单位的微脊椎动物分析，沉积时的年平均温度明显高于13摄氏度，普遍潮湿。然而，尽管大多数物种都是水边的居民，但在湖泊附近存在一个开放的景观。这里报告的数据清楚地支持了这样的观点：早期人类对欧洲的占领受到气候和环境条件的强烈限制，而不是受到地理或文化因素的限制。(C)2015爱思唯尔有限公司版权所有。
The early Pleistocene site of Barranco Leon (Guadix-Baza Basin, SE Spain), dated to 1.4 Ma (millions of years ago), records the oldest hominin occurrence in Western Europe, as evidenced by the discovery of one tooth and thousands of Mode 1 stone tools. In this paper a detailed analysis of the microvertebrate content of the D1 and D2 units from this site is presented. The early Pleistocene in the Guadix-Baza Basin is characterized by a sharp climatic deterioration, which possibly impeded the settlement of this region by the early hominin population from the southern Caucasus. Shortly afterwards, when the climatic conditions were again favorable, a hominin presence is suddenly evidenced at the units D1 and D2 of Barranco Leon. According to the microvertebrate analysis of these units, the mean annual temperature at the time of deposition was significantly higher than 13 degrees C, with prevalent humid conditions. However, although most of the species were inhabitants of water edges, an open landscape was present in the vicinity of the lake. The data reported here clearly support the idea that the early hominin occupation of Europe was strongly constrained by climatic and environmental conditions, rather than by physiography or cultural factors.
