FIRST REVIEW OF THE LYNCODONTINI MATERIAL (MUSTELIDAE, CARNIVORA, MAMMALIA) FROM THE LOWER PLEISTOCENE ARCHAEO-PALAEONTOLOGICAL SITES OF ORCE (SOUTHEASTERN SPAIN)

Two archaeo-palaeontological Lower Pleistocene sites of Orce (Baza Basin, SE Spain), Fuente Nueva 3 (1.3 Ma) and Barranco León (1.4 Ma), preserve some of the earliest evidences of human presence in the European continent. During the 2013 field season, a small Lyncodontini mustelid mandible was found at Fuente Nueva-3. This finding was accompanied by a lower canine (c1), also from the same site, and a lower fourth premolar (p4) from Barranco León. Here, we report on the morphological and biometrical study of these materials, in comparison to other Eurasian Pliocene-Pleistocene species of the tribe Lyncodontini. The analyses revealed an affinity between the taxon from Fuente Nueva-3 and Barranco León with the small-sized European species Martellictis ardea (Gervais, 1848-1852), allowing us to ascribe the described material to the latter species. The presence of M. ardea in the sites of Orce is the southernmost occurrence of the species in the Iberian Peninsula and an important finding in the scarce fossil record of Lyncodontini in Europe

Villafranchian large mammals from the Iberian Peninsula : paleobiogeography, paleoecology and dispersal events

The Pleistocene of the Iberian Peninsula is currently a focus of intense paleontological, archaeological and geological research. To a large extent, these inquiries are intended to decipher the ecological factors that might have conditioned early Homo dispersalsinto the European continent during the late Early Pleistocene. In this respect, the research carried out during the last twenty years in several areas of the Iberian Peninsula (the Guadix-Baza Basin, the Sierra de Atapuerca, the Vallparadís Section and the Banyoles-Besalú Basin) have yielded a large amount of new significant data. Here we review such data and provide for the first time a comprehensive synthesis from a faunal, geologi-cal and paleoecological perspectives, by focusing on the relationship between paleoenvironmental conditions and early human dispersals during the late Early Pleistocene in the Iberian Peninsula. In particular, the Iberian fossil record of Early to Late Villafranchian large mam-mals is synthesized, on the basis of recent publications and unpublished data collected by the authors during the last five years, in order to provide the adequate faunal and paleocological framework for understanding the factors that limited or conditioned human dispersal events.El Pleistoceno de la Península Ibérica es actualmente foco de intensa investigación paleontológica, arqueológica y geológica. En gran medida, estos trabajos están encaminados a descifrar los factores ecológicos que podrían haber condicionado las dispersiones de los Homo iniciales hacia Europa durante el Pleistoceno inferior. En este sentido, la investigación realizada durante los últimos veinte años en diversas zonas de la Península Ibérica (la Cuenca de Guadix-Baza, la Sierra de Atapuerca, la Sección de Vallparadís y la Cuenca de Banyoles-Besalú) ha proporcionado una gran cantidad de nuevos datos significativos. Aquí revisamos estos datos y se proporciona por primera vez una síntesis exhaustiva desde una perspectiva paleontológica, paleoecológica y geológica, centrándonos en las relaciones entre las condi-ciones paleoambientales y las dispersiones de los primeros humanos en el Pleistoceno inferior de la Península Ibérica. Concretamente, se sintetiza el registro fósil ibérico de grandes mamíferos villafranquienses en base a publicaciones recientes y datos inéditos recopilados por los autores en los últimos cinco años, para así proporcionar el marco faunístico y paleoecológico adecuado para comprender los factores que limitaron o condicionaron los eventos de dispersión humana

Hominins, mammoths, saber-tooths and giant hyenas in the Early Pleistocene of the Baza Basin (SE Spain)

The Baza Basin preserves an exceptional Plio-Pleis- tocene palaeontological record, which includes the earliest evidence of human presence in western Eu- rope, dated to ~1.4 Ma, coming from the sites of Barranco León and Fuente Nueva-3, in the vicinity of the town of Orce. In this geographical region, early Homo coexisted and likely competed with the giant, short-faced hyena Pachycrocuta brevirostris for the exploitation of prey carcasses abandoned by saber-tooth cats (Megantereon and Homotheri- um). The presence of these hypercarnivorous felids favored the surviving of both scavenging species (Homo and Pachycrocuta), as they exploited their prey to a lesser extent than the living pantherine felids. In this context, proboscideans were an ex- ploited food resource, as evidenced by the presence of a partial skeleton of the mammoth Mammuthus meridionalis in Fuente Nueva-3, which was sur- rounded by lithic artifacts and hyena coprolites. This association suggests that both hominins and hyenas fed on the mammoth carcass. Some paths for elucidating their pattern of access to these re- sources are also discussed.The symposium and the volume "Human-elephant interactions: from past to present" were funded by the Volkswagen Foundation

Déjà vu: a reappraisal of the taphonomy of quarry VM4 of the Early Pleistocene site of Venta Micena (Baza Basin, SE Spain)

Venta Micena, an Early Pleistocene site of the Baza Basin (SE Spain), preserves a rich and diverse assemblage of large mammals. VM3, the main excavation quarry of the site, has been interpreted as a den of the giant hyaena Pachycrocuta brevirostris in the plain that surrounded the Baza palaeolake. Taphonomic analysis of VM3 has shown that the hyaenas scavenged the prey previously hunted by the hypercarnivores, transported their remains to the communal den, and consumed the skeletal parts according to their marrow contents and mineral density. In a recent paper (Luzón et al. in Sci Rep 11:13977, https://doi.org/10.1038/s41598-021-93261-1, 2021), a small sample of remains unearthed from VM4, an excavation quarry ~ 350 m distant from VM3, is analysed. The authors indicate several differences in the taphonomic features of this assemblage with VM3, and even suggest that a different carnivore could have been the agent involved in the bone accumulation process. Here, we make a comparative analysis of both quarries and analyse more skeletal remains from VM4. Our results indicate that the assemblages are broadly similar in composition, except for slight differences in the frequency of megaherbivores, carnivores and equids according to NISP values (but not to MNI counts), the degree of bone weathering, and the intensity of bone processing by the hyaenas. Given that VM4 and VM3 were not coeval denning areas of P. brevirostris, these differences suggest that during the years when the skeletal remains were accumulated by the hyaenas at VM3, the rise of the water table of the Baza palaeolake that capped with limestone the bones was delayed compared to VM4, which resulted in their more in-depth consumption by the hyaenas

Insights on the Early Pleistocene Hominin Population of the Guadix-Baza Depression (SE Spain) and a Review on the Ecology of the First Peopling of Europe

The chronology and environmental context of the first hominin dispersal in Europe have been subject to debate and controversy. The oldest settlements in Eurasia (e.g., Dmanisi, ∼1.8 Ma) suggest a scenario in which the Caucasus and southern Asia were occupied ∼0.4 Ma before the first peopling of Europe. Barranco León (BL) and Fuente Nueva 3 (FN3), two Early Pleistocene archeological localities dated to ∼1.4 Ma in Orce (Guadix-Baza Depression, SE Spain), provide the oldest evidence of hominin presence in Western Europe. At these sites, huge assemblages of large mammals with evidence of butchery and marrow processing have been unearthed associated to abundant Oldowan tools and a deciduous tooth of Homo sp. in the case of BL. Here, we: (i) review the Early Pleistocene archeological sites of Europe; (ii) discuss on the subsistence strategies of these hominins, including new estimates of resource abundance for the populations of Atapuerca and Orce; (iii) use cartographic data of the sedimentary deposits for reconstructing the landscape habitable in Guadix-Baza; and (iv) calculate the size of the hominin population using an estimate of population density based on resource abundance. Our results indicate that Guadix-Baza could be home for a small hominin population of 350–280 individuals. This basin is surrounded by the highest mountainous reliefs of the Alpine-Betic orogen and shows a limited number of connecting corridors with the surrounding areas, which could have limited gene flow with other hominin populations. Isolation would eventually lead to bottlenecks, genetic drift and inbreeding depression, conditions documented in the wild dog population of the basin, which probably compromised the viability of the hominin population in the medium to long term. This explains the discontinuous nature of the archeological record in Guadix-Baza, a situation that can also be extrapolated to the scarcity of hominin settlements for these ancient chronologies in Europe

Une nouvelle espèce de chien du site du Pléistocène inférieur de Venta Micena (Orce, bassin de Baza, Espagne)

Le gisement de Venta Micena (Orce, Espagne), 1.6 Ma environ, possède un des plus importants registres paléontologiques de faune de grands mammifères du Pléistocène inférieur d’Europe. Dans ce travail, nous décrivons des spécimens attribués au genre Canis Linnaeus, 1758 dans le contexte des chiens fossiles du Villafranchien supérieur et de l’Epivillafranchien d’Eurasie. Les données anatomiques et métriques suggèrent que le Canis de Venta Micena diffère des espèces courantes à ces époques, Canis etruscus Forsyth Major, 1877 et Canis arnensis Del Campana, 1913. Il se place à la base de la lignée plus récente appelée Canis mosbachensis Soergel (1925), déjà mentionnée dans deux gisements du complexe d’Orce légèrement plus récents, Barranco León et Fuente Nueva-3, datés d’1,4 Ma environ. L’anatomie primitive du fossile de Venta Micena, avec des caractères semblables à ceux du Canis caucasien de Dmanisi, daté de 1,8 Ma, conforte la création d’une nouvelle chrono-espèce de canidé, Canis orcensis n. sp., qui prend son nom de la ville d’Orce. Les données paléoécologiques suggèrent que cette espèce consommait plus de viande (i.e., une tendance à la hypercarnivorie) que d’autres canidés de taille semblable du Pléistocène inférieur qui avaient des régimes alimentaires plus omnivores.The site of Venta Micena (Orce, Spain), c. 1.6 Ma, preserves one the best paleontological records of the early Pleistocene large mammals fauna in Europe. Here we describe the specimens of the genus Canis Linnaeus, 1758 in the context of the late Villafranchian and Epivillafranchian fossil dogs from Eurasia. Anatomical and metric data suggest that the Venta Micena Canis form differs from the classical records of Canis etruscus Forsyth Major, 1877 and Canis arnensis Del Campana, 1913, and that it forms part of the younger Canis mosbachensis Soergel (1925) lineage, also recorded in two slightly younger sites of the Orce site complex, Barranco León and Fuente Nueva-3, dated to c. 1.4 Ma. The anatomy of the Venta Micena fossil material shows features that resemble the Canis forms from the Caucasian site of Dmanisi, dated to 1.8 Ma, and Canis ex gr. C. mosbachensis. Nevertheless, dental peculiarities support the creation of a new chrono-species, Canis orcensis n. sp., from the town of Orce. Morphological and paleoecological data suggest that this species probably consumed more vertebrate flesh than other similar sized early Pleistocene canids (i.e., a trend to hypercarnivory), which had more omnivorous dietary habits.</p

Climate and environmental conditions in the Guadix-Baza Depression during the first hominin dispersal in Western Europe: Comment on Saarinen et al. (2021)

Two late Early Pleistocene archaeological sites of the Guadix-Baza Depression (GBD) in SE Spain, Barranco León (BL) and Fuente Nueva 3 (FN3), dated to ∼1.4 Ma (Palmqvist et al., 2016), document the earliest evidence on hominin dispersal in Western Europe. Venta Micena (VM), an older palaeontological site (1.6–1.5 Ma), records the community of large mammals that preceded this dispersal event (Palmqvist et al., 2022a). Based on dental ecometrics and patterns of tooth mesowear of herbivorous mammals, Saarinen et al. (2021) have provided estimates of mean annual temperature (MAT), minimum annual temperature (MINT), mean annual precipitation (MAP) and net primary production (NPP) for these sites. Their estimates for BL/FN3 differ from other studies of their team, derived from the herpetofaunal assemblages of the sites (e.g., Agustí et al., 2009; Blain et al., 2011, 2016; Martínez-Monzón et al., 2022). Moreover, their MAP and NPP values for VM disagree with the inferences from other analyses, which they do not cite (e.g., García-Aguilar et al., 2014, 2015; Rodríguez-Gómez et al., 2016, 2017).Depto. de Geodinámica, Estratigrafía y PaleontologíaFac. de Ciencias GeológicasTRUEMinisterio de Ciencia e InnovaciónJunta de AndalucíaComunidad de MadridUniversidad Complutense de Madridpu

On the fallacy of using orthogenetic models of rectilinear change in arvicolid teeth for estimating the age of the first human settlements in Western Europe

Lozano-Ferna´ndez et al. (Lozano-Ferna´ndez I, Blain HA, Lo´pez-Garcı´a JM, Agustı´ J. 2014. Biochronology of the first hominid remains in Europe using the vole Mimomys savini: Fuente Nueva 3 and Barranco Leo´n D, Guadix-Baza Basin, south-eastern Spain. Hist Biol: Int J Paleobiol. doi:10.1080/08912963.2014.920015) recently published age estimates for two Late Villafranchian sites of Orce (Guadix-Baza basin, SE Spain), BL-D and FN-3, which provide some of the earliest evidence of human presence in Western Europe. The estimates were obtained from mean Lm1 values of the water vole Mimomys savini preserved in the sites and a couple of rectilinear equations derived in the Atapuerca TD section for site age on tooth length. However, this chronometric tool has problems that discourage its use in biostratigraphy, including: (1) the assumption of an orthogenetic trend of Lm1 increase during the evolution of the M. savini/Arvicola lineage; (2) the use of a chronology for the TD section not supported by original ESR data; (3) the discrepancies between the mean Lm1 values published for the TD levels and (4) the chronological ranges predicted when the standard deviations are used, which are exceedingly large as to be of value for biostratigraphic purposes. As a result, the pseudo numerical ages estimated for the Orce sites only add noise to the timing of the first human dispersal in Europe, which is based on a combination of results from well-established techniques such as palaeomagnetism, biostratigraphy and ESR.This study has been funded by the ‘Consejerı´a de Educacio´n, Cultura y Deportes’ (contract Exp.

Villafranchian large mammals from the Iberian Peninsula : paleobiogeography, paleoecology and dispersal events

The Pleistocene of the Iberian Peninsula is currently a focus of intense paleontological, archaeological and geological research. To a large extent, these inquiries are intended to decipher the ecological factors that might have conditioned early Homo dispersalsinto the European continent during the late Early Pleistocene.

Déjà vu: on the use of meat resources by sabretooth cats, hominins, and hyaenas in the Early Pleistocene site of Fuente Nueva 3 (Guadix-Baza Depression, SE Spain)

The late Early Pleistocene archaeological site of Fuente Nueva 3 (Orce, Guadix-Baza Depression, SE Spain), dated to ~1.4 Ma, provides evidence on the subsistence strategies of the first hominin population that dispersed in Western Europe. The site preserves Oldowan tool assemblages associated with abundant remains of large mammals. A small proportion of these remains show cut marks and percussion marks resulting from defleshing and bone fracturing, and a small proportion of bones also show tooth marks. Previous taphonomic studies of FN3 suggested that the hominins had secondary access to the prey leftovers abandoned by sabretooth cats and other primary predators. However, a recent analysis by Yravedra et al. (2021) of the frequency of anthropogenic marks and tooth marks has concluded that the hominins had primary access to the carcasses of a wide variety of ungulate prey, even though the frequency of evisceration marks is strikingly low. In this rebuttal, we analyse the patterns of bone preservation in FN3, which show that the exploitation of bone marrow by the hominins after hammerstone breakage was a usual activity at the site. Our study also reviews the evidence available on the lesser abilities of sabretooth cats for carcass processing compared to pantherine felids. This reinforces the hypothesis that primary predators provided the hominins the opportunity to scavenge sizeable chunks of meat and bone marrow of their prey carcasses before the arrival of hyaenas. Finally, we also provide new inferences on resource availability and competition intensity among the members of the carnivore guild in FN3, which reinforce our interpretation that a secondary access by the Oldowan hominins to the prey leftovers of sabretooth cats was an optimal foraging strategy in the Guadix-Baza Depression
