A Late Pleistocene (MIS3) ungulate mammal assemblage (Los Rincones, Zaragoza, Spain) in the Eurosiberian–Mediterranean boundary

During the Upper Pleistocene the archaeo-paleontological sites in the Iberian Peninsula are located mainly on the coasts. Here we present for the first time a paleoenvironmental proxy for Upper Pleistocene locality (MIS3) that is in the interior peninsular, in the Moncayo Massif (Zaragoza). This is actually the boundary between Mediterranean and Eurosiberian climatic-regions. The present study is based in the site ungulates: Capra pyrenaica, wich is bigger in size than current and fossil from Mediterranean area. The horses have a small size, which is similar to that of the horses from Fontainhas and Casares. Significantly lesser in the number of rests, are the roe deer, the southern chamois, and the auroch. The study and comparison of the faunal assemblage of the locality of Los Rincones, with other sites of the Iberian MIS 3 shows a cluster of sites in the southern Peninsular, though separated, due to the abundance of C. pyrenaica. The association of Los Rincones is similar to the southern peninsular sites such as Nerja, Gorham Cave, Cova Beneito, Zafarraya. The ungulate assemblage of Los Rincones represents a landscape with temperate climate, presence of steppe, and patches of forest, similar to the current landscape surrounding the cavity today.

“…I have no knowledge of the frequency of enamel islets on the dP3 in either species. According to my data [53], the presence of a pli protostylid is as frequent in E. africanus as in E. burchelli, and the dimensions of the dp2-dp4 are also the same (approximately 85 mm). However, two features seem to support Thomas' attribution: the elongated metaconids and the shallow ectoflexids.…”

Discussion of the phylogenetic relations between Plesippus, Allohippus, and Equus. Descriptions and illustrations of 30 Equid extant and fossil species younger than 2 Ma. Particular attention is given to slender forms with short protocones usually referred to ‘Equus altidens’ from Süssenborn and Untermassfeld (Germany), Akhalkalaki and Dmanisi (Georgia), Pirro (Italy), Venta Micena (Spain) and Aïn Hanech (Algeria). Occurrence of Asinine features in fossil taxa from Africa, Greece, Mongolia, and North-Eastern Siberia. Supplementary materials include additional discussions and photographs of fossils in particular from Süssenborn (especially those referred to E. altidens and E. marxi by Reichenau) and from Dmanisi from where a new species is described.

“…Interspecific variation in the Equidae was examined based on longbone and dental samples of the extant species E. przewalskii , Equus caballus , E. hemionus , E. burchelli , Equus grevyi , E. zebra , E. asinus and Equus africanus , ponies and Arabian horses (Eisenmann & De Giuli, 1974; Eisenmann, 1979, 1980, 1981; Dive & Eisenmann, 1991; Johnstone, 2004). The E. przewalskii material almost exclusively represents animals reared in zoological gardens in Europe, although a few wild‐caught animals are contained in the sample.…”

Implications of age variation and sexual dimorphism in modern equids for Middle Pleistocene equid taxonomy

Interspecific variation in the equid lineage is limited when compared with other large mammal lineages, while a considerable amount of intraspecific ecomorphological variation occurs. This has led to considerable debate regarding the taxonomic status of palaeontological and archaeological equid remains. The possible confounding impact of sex and age variation on analyses of archaeological equid remains has so far remained untested. This could be especially problematic when it is unknown whether an assemblage contains more than one equid species, breed or hybrid. Here, sex and age variation in modern equid species is examined and compared to variation in Pleistocene equid assemblages from northwest Europe. Sex variation in the longbones of modern equid species was found to be lower than variation over time. Similarly, age variation in dental elements of the same species is predominantly lower than diachronic variation, although caution needs to be taken when an archaeological assemblages consists mostly of elements at a similar wear stage.To assess whether late Middle Pleistocene caballoid horse fossils should be assigned to multiple species or be considered to form a monospecific group, the coefficients of variation for measurements on fossil horse remains were compared with those for modern equid specimens. Results indicate that the fossil assemblages are similarly variable to samples of modern material. Taken as a whole, the late Middle Pleistocene caballoid horse lineage is equally variable to an assemblage of modern ponies of a variety of different breeds. This implies that the variation observed between samples dating from different parts of the Middle Pleistocene can be characterised as intraspecific variation within a single species reflecting ecomorphological adaptations to the changeable Pleistocene climate.
