New paleoecological perspectives on Late Pleistocene Neanderthals in northern Balkans: the rodent assemblages from Smolućka cave (Serbia)

Abstract

During the Late Pleistocene, the Balkans came to be an important region with many isolated areas, enabling fauna, alongside Neanderthals, to thrive in the area. This work is focused on paleoenvironmental and paleoclimatic changes that occurred in the northern Balkan Peninsula with a special focus on fossil record from Smolućka cave aging from MIS 5 to MIS 3. Based on available data, an attempt has been made to establish a synthetic chronological context for the faunal assemblages recovered from Smolućka cave. Tentative attribution of layer 5 to MIS 5 relies on the interstadial pattern of our reconstructions, with favorable climate conditions for a large diversity of species and with mean annual temperature (MAT) reaching up to 3 °C higher than present values and abundant rainfall in the area. Cold conditions for MIS 4 are not present in Smolućka, although layer 4 (late MIS 5 or early MIS 4) shows somewhat dryer and cooler climate when compared with other layers. Layers 3z and 3 (MIS 3) are characterized by temperate and humid conditions together with a complex system of mosaic habitats with high environmental heterogeny but generally favorable conditions for a large diversity of life. Although still not fully chronologically constrained, Smolućka cave presents an interesting opportunity for future research, in the time period when only Neanderthals occupied the Balkans and thrived in local conditions. The transition between the Neanderthals and anatomically modern humans has not yet been established but can be expected in future research.
