El Salt is an important reference site for understanding the extinction of Neanderthal populations in the eastern Iberian Peninsula during MIS 3. In this paper, we describe the small mammal assemblage from Stratigraphic Unit V, the youngest unit with evidence of human presence, based on nearly 1300 specimens. A total of seven rodents (Microtus arvalis, Microtus duodecimcostatus, Microtus cabrerae, Sciurus vulgaris, Arvicola sapidus, Eliomys quercinus and Apodemus sylvaticus), three insectivores (Talpa occidentalis, Crocidura sp., Sorex sp.) and one lagomorph (Oryctolagus cf. cuniculus) were identified. Palaeocological analyses point to drier conditions in this part of the stratigraphic sequence, supporting the hypothesis that an aridification scenario may have played a role in the extinction of the Neanderthal groups inhabiting this region of the Iberian Peninsula.

El Salt是了解MIS 3期间伊比利亚东部半岛尼安德特人种群灭绝的重要参考地点。在本文中，我们基于第5层地层单元（这是最年轻的有人类存在证据的单元）组合的小型哺乳动物。 1300个标本。共有七个啮齿类（田鼠arvalis，田鼠duodecimcostatus，田鼠cabrerae，松鼠，Arvicola sapidus，园睡鼠属quercinus和姬鼠），三种食虫（TALPA悬铃木，麝属，鼩属）和一个兔类动物（孔眼参比 cuniculus）进行了鉴定。古生物学分析指出，地层层序的这一部分条件较干燥，这支持了这样的假说，即干旱化情景可能在居住在伊比利亚半岛这一地区的尼安德特人群体的灭绝中发挥了作用。
