During the Gravettian, Arbreda Cave was frequently occupied by hunter-gatherer communities. Within this period, the archeological levels E (Iberian Middle Gravettian) and D (Final Gravettian), dated to ca. 26–20 kyr ¹⁴C BP, are of particular interest, since fieldwork carried out during the 1980s revealed dense accumulations of archeological materials with remarkable concentrations of burnt remains. The archeozoological and taphonomic studies conducted with faunal remains recovered from both levels have provided essential information about subsistence activities; however, the concentrations of these remains have not been subjected to spatial distribution analysis. In recent decades, spatial analysis has become a key tool for deciphering the formation dynamics of archeological levels, as well as for offering valuable clues with which to understand the relation of the occupants with the morphology of the site cavities. The aims of this paper are to pinpoint the principal activity areas of both Gravettian levels of Arbreda Cave focusing on the location of main hearth-related assemblages and to interpret these activity areas in terms of the use of the space by hunter-gatherer groups. To achieve these goals, our research has been based on the processing of archeozoological and taphonomic data obtained in recent studies applying different spatial statistics methods, including techniques of density analysis and spatial correlation. Furthermore, for each level, the results obtained from the geostatistical approaches are supplemented by a detailed taphonomic analysis of the complete assemblage of remains recovered from the principal hearth-related square. Finally, in each case, an accurate analysis of the burnt remain assemblage of each square provides further elucidation of the large amount of combusted remains in the area. The study reveals that hunter-gatherer communities established themselves in particular areas of the cave, close to the north wall and beneath the existing roof of the rock shelter. The dense accumulations of different remains found in these areas has enabled us to hypothesize about its hearth-related origin, where hearths would have been settled and marrow exploitation activities would have been carried out around them. Furthermore, the high rate of breakage and charred and calcined remains and a relatively high percentage of burnt spongy bones indicate that bones were used as fuel to supplement firewood. On the whole, the low level of space organization complexity of levels E and D main activity areas supports a seasonal pattern of occupation during the Iberian Middle Gravettian and Final Gravettian periods.

来自 Arbreda Cave（Serinyà，东北伊比利亚半岛）的 Gravettian 狩猎采集者的居住环境：从考古动物证据中搜索活动区域

在 Gravettian 期间，Arbreda Cave 经常被狩猎采集社区占据。在此期间，考古级别 E（伊比利亚中部 Gravettian）和 D（最终 Gravettian）可追溯到约 26–20 基尔¹⁴C BP 是特别令人感兴趣的，因为 1980 年代进行的实地调查揭示了考古材料的密集堆积以及显着集中的烧焦遗骸。对从这两个层面回收的动物遗骸进行的考古动物学和埋藏学研究提供了关于生存活动的重要信息；然而，这些遗骸的浓度尚未经过空间分布分析。近几十年来，空间分析已成为破译考古层面形成动力学的关键工具，并为了解居住者与遗址空洞形态的关系提供有价值的线索。本文的目的是确定 Arbreda 洞穴两个 Gravettian 层的主要活动区域，重点是与壁炉相关的主要组合的位置，并根据狩猎采集群体对空间的使用来解释这些活动区域。为实现这些目标，我们的研究基于对最近研究中获得的考古动物学和土壤学数据的处理，应用不同的空间统计方法，包括密度分析和空间相关性技术。此外，对于每个级别，从地质统计学方法获得的结果都辅以对从主要壁炉相关方格中恢复的完整遗骸组合的详细埋藏分析。最后，在每种情况下，对每个方格的燃烧遗骸组合进行准确分析，可以进一步阐明该地区的大量燃烧遗骸。研究表明，狩猎采集社区在洞穴的特定区域建立起来，靠近北壁和岩石庇护所的现有屋顶下方。在这些地区发现的不同遗骸的密集堆积使我们能够推测其与壁炉有关的起源，即在那里安置了壁炉，并在它们周围进行了骨髓开采活动。此外，较高的破损率和烧焦和煅烧残骸以及相对较高比例的烧焦海绵骨表明骨头被用作燃料来补充木柴。总的来说，
