The excavations carried out in Cova Gran de Santa Linya (Southeastern PrePyrenees, Catalunya, Spain) have unearthed a new archaeological sequence attributable to the Middle Palaeoloithic/Upper Palaeolithic (MP/UP) transition. This article presents data on the stratigraphy, archaeology, and (14)C AMS dates of three Early Upper Palaeolithic and four Late Middle Palaeolithic levels excavated in Cova Gran. All these archaeological levels fall within the 34-32 ka time span, the temporal frame in which major events of Neanderthal extinction took place. The earliest Early Upper Palaeolithic (497D) and the latest Middle Palaeolithic (S1B) levels in Cova Gran are separated by a sterile gap and permit pinpointing the time period in which the Mousterian disappeared from Northeastern Spain. Technological differences between the Early Upper Palaeolithic and Late Middle Palaeolithic industries in Cova Gran support a cultural rupture between the two periods. A series of 12 (14)C AMS dates prompts reflections on the validity of reconstructions based on radiocarbon data. Thus, results from excavations in Cova Gran lead us to discuss the scenarios relating the MP/UP transition in the Iberian Peninsula, a region considered a refuge of late Neanderthal populations.
科瓦格兰德圣利纳（西班牙加泰罗尼亚东南比利牛斯山脉）的发掘出土了一段可归因于中更新世/晚更新世过渡时期的新考古序列。本文介绍了在科瓦格兰德挖掘的三个早期更新世晚期和四个中更新世晚期地层的地层学、考古学和 14CAMS 年代数据。所有这些考古层都在 34-32 ka 的时间范围内，这是尼安德特人灭绝的主要事件发生的时间框架。科瓦格兰德最早的早期更新世（497D）和最晚的中更新世（S1B）地层被一个不育的间隔隔开，这使得我们能够确定莫斯特文化从西班牙东北部消失的时间。科瓦格兰德的早期更新世和晚期中更新世工业之间的技术差异支持了这两个时期之间的文化断裂。一系列 12 个 14CAMS 年代提示我们对基于放射性碳数据的重建的有效性进行反思。因此，科瓦格兰德的发掘结果使我们能够讨论与伊比利亚半岛中更新世/晚更新世过渡相关的情景，该地区被认为是晚期尼安德特人种群的避难所。
