This paper offers a temporal analysis of the megalithic group of La Lora in the context of northern Iberian Plateau megalithism. For this purpose, 67 accelerator mass spectrometry radiocarbon (AMS 14C) dates were obtained on human bone from the minimum number of individuals recovered from nine tombs. This is the first systematic dating project carried out in this dolmen group and has enabled the chronology of the main funerary series to be updated. The results reveal that the actual funerary use dates mainly to the 4th millennium BC, although, as deduced from the archaeological material, some tombs were reused in later periods. Additionally, the significant architectural polymorphism of the group, consisting mainly of simple dolmens and large corridor tombs, suggested a temporal evolution to monumentality. However, the dating shows a more complex reality, since it is likely that the large tombs functioned as funerary pantheons during the 4th millennium BC, characterized by a cyclical and recurrent use. In contrast, the simpler structures were preferred to be of shorter use and restricted to the first half of the 4th millennium.

本文对伊比利亚高原北部巨石群背景下的拉洛拉巨石群进行了时间分析。为此，从九个坟墓中出土的最少数量的个体中获得了67 个加速器质谱放射性碳 (AMS 14 C) 数据。这是在该支石墓群中开展的第一个系统测年项目，使主要随葬品系列的年表得以更新。结果表明，实际陪葬品的使用主要可以追溯到公元前四千年，尽管根据考古材料推断，一些坟墓在后来的时期被重复使用。此外，该群建筑的显着多态性，主要由简单的支石墓和大型走廊墓组成，表明了向纪念性的时间演变。然而，年代测定显示了更为复杂的现实，因为这些大型坟墓很可能在公元前四千年期间充当了陪葬万神殿，其特点是周期性和反复使用。相比之下，更简单的结构更倾向于使用时间较短，并且仅限于第四个千年的上半叶。
