The dataset contains six shape files with its associated data: The files BL_LvlD1_ODA, BL_LvlD2_ODA and BL_LvlE_ODA correspond to the Occupied Distribution Areas (ODA) of the amphibian and squamata reptile species present in the analysed levels of the Early Pleistocene Barranco León site. The ODA for these levels has been calculated by projecting the niche envelope of Ophisaurus sp. over the initial distribution areas of the species. The file FN3_Lvl5 corresponds to the distribution areas of the amphibian and squamata reptile species present in the analysed level 5 of the Early Pleistocene site of Fuente Nueva 3. This distribution was calculated by the application of the Mutual Ecogeographic Range method. The climatic and palaeoclimatic parameters presented in the related publication have been calculated from these files. The file OrceMuni_Actual corresponds to the geographical area of the municipality of Orce from where the current climatic values have been calculated. The file HyKo_ODA corresponds to the calculated ODA for Hyallosaurus koellikeri. This refined distribution has been calculated by removing areas exceeding the maximum altitudinal limit of the specie (i.e., 2000 m), and by selecting the areas with the vegetation cover requirements described for H. koelliekeri (i.e., evergreen broadleaf tree cover values above 13.1%). Shape files are projected in the WGS 84 geographic reference coordinate system.
