The TD6 unit of the Gran Dolina contains an assemblage of the Early Pleistocene, interpreted firstly as a home base. More recently has been proposed a transported origin of the remains according to the sedimentology. Following this model, the remains should be dragged or lagged in a predictable pattern related to their weight, density, shape, and size. Conversely, the debris generated in an undisturbed residential camp should retain spatial relations of codependence caused by the depositional process, not related to inherent variables of materials. To check if the remains were recovered in their original depositional place (aggregated) or are the product of transportation (segregated or random spatial relation), we have evaluated different variables: the spatial arrangement between osteological and lithic tools; the integrity of the bones and their structural characters (shape and tissue composition); postdepositional modifications; and the specimen size distribution. The combined results indicate that the layers that conform the TD6.2 subunit were undisturbed, while TD6.1 was affected by postdepositional processes, probably water flows, resulting in a lagged assemblage. In conclusion, TD6.2 is best interpreted as a well-preserved home base and should play a key role in studies of the behavior of the first European populations.

Gran Dolina的TD6单元包含早期更新世的组合，首先被解释为家庭基地。根据沉积学，最近提出了遗骸的运输来源。按照此模型，应该以与遗骸的重量，密度，形状和大小有关的可预测模式拖动或滞留遗骸。相反，在未受干扰的住宅营地中产生的碎屑应保留由沉积过程引起的相互依赖性的空间关系，而与材料的固有变量无关。为了检查这些遗骸是在原始沉积位置（聚集的）还是运输的产物（分离的或随机的空间关系）中恢复的，我们评估了不同的变量：骨科和石器之间的空间排列；骨骼的完整性及其结构特征（形状和组织组成）；沉积后修饰；和样本尺寸分布。合并结果表明，符合TD6.2亚基的层不受干扰，而TD6.1受沉积后过程（可能是水流）的影响，导致组装滞后。总之，最好将TD6.2解释为保存良好的本国基础，并应在研究欧洲第一批人口的行为中发挥关键作用。
