Buena Pinta Cave (Pinilla del Valle, Madrid) has been interpreted as a hyena den with sporadic occupations of Homo neanderthalensis in the western part of the site (level 23). In order to identify the different formation processes in this area of the site, spatial analyses have been carried out with GIS and spatial statistics based on the taphonomic analysis of the faunal remains. Based on the vertical and sectional analyses of the assemblage, it has been possible to determine that level 23 actually corresponds to three archaeological levels with well-differentiated characteristics: a lower level with few faunal remains and fossil-diagenetic alterations related to humid environments associated with clays; an intermediate level with a high percentage of remains with water-related modifications and evidences of transport; and an upper level delimited mainly thanks to by a paraconformity evidenced by the concentration of weathered remains in this area and a significant reduction in remains with water-related alterations above. The results obtained show the necessity to redefine field layers and the usefulness of integrating taphonomic data and spatial studies.

布埃纳平塔洞穴（Pinilla del Valle，马德里）被解释为鬣狗巢穴，在该遗址的西部（第 23 层）有零星的尼安德特人居住。为了识别该遗址区域的不同形成过程，基于动物遗骸的埋藏学分析，利用GIS和空间统计进行了空间分析。根据组合的垂直和剖面分析，可以确定第 23 层实际上对应于三个具有良好分化特征的考古层：较低的层，动物遗骸很少，以及与潮湿环境相关的化石成岩蚀变。粘土；中等水平，有高比例的遗骸具有与水有关的变化和运输证据；上层的划分主要是由于该地区风化遗骸的集中以及上面与水有关的蚀变的遗骸的显着减少所证明的准整合性。获得的结果表明重新定义场层的必要性以及整合埋藏数据和空间研究的有用性。
