Abstract

One of the markers of the Late Pleistocene is highly fluctuating climatic conditions, with the Last Glacial Maximum (LGM, 26.5–19 ka cal before present (BP)) known to be one of the coldest periods. This work explores how the environment of north-eastern Iberia changed in relation to global climatic changes experienced during the Late Pleistocene, specifically around the LGM. Small mammal assemblages from Cudó cave (Tarragona, Spain) were used considering their well-known reliability for palaeoenvironmental reconstructions. Based on the taxonomic identification and the taphonomic analysis, several methodologies covering both qualitative and quantitative approaches were used to obtain the palaeoenvironmental information corresponding to level 107 and level 105 of Cudó cave (31.2–24.4 and 15.5–10.2 ka cal BP, respectively). The taphonomic results obtained point out owls (category 3) as the main accumulator of the small mammals. The palaeoenvironmental reconstruction shows that both levels experienced colder (−7.2oC/–4.4 °C) and wetter (+848 mm/ + 586 mm) climatic conditions than nowadays. However, in level 107 the environment was dominated by mid-European species and rocky landscape, while in level 105 it was dominated by Mediterranean species and woodland habitat. These conditions are consistent with the trend in north-eastern Iberia following several climatic events before and after the LGM coinciding with the period of Cudó cave assemblages.
