The exceptional presence of megaloceros giganteus in North-Eastern Iberia and Its palaeoecological implications: the case of Teixoneres cave (Moià, Barcelona, Spain)

Publication . Uzunidis, Antigone; Rivals, Florent; Rufà, Anna; Blasco, Ruth; Rosell, Jordi

In this article we announce the discovery of the first remains of Megaloceros giganteus found in Catalonia (north-eastern Iberia) from the Late Pleistocene: a fragment of maxillary. Dated between 35,000 and 37,000 cal BP, it is also among the youngest occurrence of this taxon in the Iberian Peninsula, while its last known occurrence is dated to the Neolithic period. Through a comparison with the giant deer of the northern Pyrenees, we analyzed the herbivore guilds in which this taxon was associated to understand the context in which it was able to enter the Iberian Peninsula. By comparing its diet with those of specimens from Northern Europe, we detail the ecological adaptations of this taxon in this new environment. We suggest that Megaloceros accompanied the migrations of cold-adapted species by taking advantage of the opening of corridors on both sides of the Pyrenees during the coldest periods of the Late Pleistocene. The diet of the Iberian individuals, which is oriented towards abrasive plants, suggests an adaptation to a different ecological niche than that found in Northern European individuals. The northern Iberian Peninsula may have been an extreme in the geographical expansion of M. giganteus. More specimens will be needed in the future to establish the variability of the southern Megaloceros populations.

Speciated mechanism in Quaternary cervids (Cervus and Capreolus) on both sides of the Pyrenees: a multidisciplinary approach

Publication . Uzunidis, Antigone; Rufà, Anna; Blasco, Ruth; Rosell, Jordi; Brugal, Jean-Philip; Texier, Pierre-Jean; Rivals, Florent

Cervids, and especially the red deer Cervus elaphus, are among the most regularly and abundantly recorded ungulates in Pleistocene/Paleolithic bone assemblages. Numerous Pleistocene or Holocene subspecies have been described, reinforcing their status as essential proxies for environmental and chronological reconstructions. Despite this, at the beginning of the Late Pleistocene, their diversity seems to have decreased. In this study, we analysed teeth and some postcranial elements of Cervus and Capreolus from north-eastern Iberia and south-eastern France to clarify their morphological characteristics and ecological adaptations. We describe a transitional form in north-eastern Iberia between the western European stock and the current form C. e. hispanicus. Such sub-speciation processes are connected to biogeographical factors, as there were limited exchanges between north-eastern Iberia and the northern Pyrenees, whereas the north-western part of the peninsula seems more connected to the northern Pyrenees. The anatomical plasticity (morpho-functional adaptation and body size) of red deer is connected to dietary flexibility (dental meso- and microwear). Conversely, Capreolus shows greater morphological and ecological homogeneity. Body size variations seem directly correlated with their ability to browse throughout the year. The marked differences between the eco-bio-geographical responses of the two taxa can be explained by their habitat selection.

Neanderthal hunting grounds: the case of Teixoneres Cave (Spain) and Pié Lombard rockshelter (France)

Publication . Uzunidis, Antigone; Blasco, Ruth; Brugal, Jean-Philip; Fourcade, Tiffanie; Ochando, Juan; Rosell, Jordi; Roussel, Audrey; Rufà, Anna; Sánchez Goñi, Maria Fernanda; Texier, Pierre-Jean; Rivals, Florent

The study of Neanderthal-Environment interactions very often lacks precise data that match the chronogeographical frame of human activities. Here, we reconstruct Neanderthals' hunting grounds within three distinct habitats using dental microwear analysis combined with zooarchaeological data. The predation patterns toward ungulates are discussed in term of frequency (NISP/MNI) and potential meat intake (MAM). Unit IIIa of Teixoneres Cave (MIS 3, NE Spain) corresponds to a mosaic landscape, Unit IIIb was more forested, and, in the "Ensemble" II of Pie Lombard (MIS 4, SE France), forest cover dominated. At Pie Lombard, Neanderthals rely on a high diversity of taxa from closed and semi-open hunting grounds, mostly two ungulate species as well as rabbits and several bird taxa. At Teixoneres Cave, mainly open areas are exploited in summer with a predation mostly focused on large gregarious ungulates. The larger size of ungulate herds in open spaces may have allowed Neanderthals to restrict their subsistence behaviour only to very few species, in specific hunting strategies. In Unit IIIa, they do not appear to have made any selection within the most abundant species, while in Unit IIIb, they focused on aurochs and also opportunistically and heavily on newborn red deer. Neanderthal subsistence strategies seem, therefore, only partially linked to the hunting grounds they had access to. While it impacted the diversity of the prey they selected, Neanderthal groups were able to develop distinct hunting strategies within similar environments.
