The Sobrarbe-Pirineos UNESCO Global Geopark shows an extremely well-developed underground karst relief as a result of the great abundance and thickness of its limestone formations. The most important Pleistocene vertebrate site within the Geopark is Coro Tracito Cave at Tella. The fossil association is made up exclusively of bones belonging to Ursus spelaeus from the upper Pleistocene, accumulated over several thousand years. Based on scientific analysis of the fossil bones, an interesting public outreach project has been organized, involving the refurbishment of the site within the cave and the creation of a permanent exhibition called the Tella Cave Bear Museum. These two infrastructures are visited by thousands of tourists each year and constitute the main geoscientific tourist attraction of the Sobrarbe-Pirineos Geopark.

- Abstract
The red-toothed shrews (Soricinae) are the most widespread subfamily of shrews, distributed from northern South America to North America and Eurasia. Within this subfamily, the tribe Nectogalini includes the fossil species Nesiotites hidalgo recorded from the Late Pleistocene to Holocene of the Balearic Islands (Western Mediterranean). Although there is a consensus about the close relationship between the extinct red-toothed shrew genera Nesiotites and Asoriculus based on morphology, molecular data are necessary to further evaluate the phylogenetic relationships of the Balearic fossils. We obtained a near complete mitochondrial genome of N. hidalgo, allowing the first molecular phylogenetic analysis of this species. Analyses based on 15, 167 bp of the mitochondrial genome placed N. hidalgo as close relative to the extant Himalayan shrew (Soriculus nigrescens), and a combined analysis using molecular and morphological data confirm that N. hidalgo and Asoriculus gibberodon are sister-taxa with S. nigrescens as the immediate outgroup. Molecular clock and divergence estimates suggest that the split between N. hidalgo and its closest living relative occurred around 6.44 Ma, which is in agreement with the previously proposed colonisation of the Balearic Islands from mainland Europe by nectogaline shrews during the Messinian Salinity Crisis (5.97–5.33 My ago). Our results highlight that it is possible to retrieve genetic data from extinct small mammals from marginal environments for DNA preservation. Additional finds from the fossil record of Soricinae from the Eurasian Late Miocene/Early Pliocene are needed to shed further light on the still confusing taxonomy and paleobiogeography of this clade.

Current knowledge of the evolution of the postcranial skeleton in the genus Homo is hampered by a geographically and chronologically scattered fossil record. Here we present a complete characterization of the postcranium of the middle Pleistocene paleodeme from the Sima de los Huesos (SH) and its paleobiological implications. The SH hominins show the following: (i) wide bodies, a plesiomorphic char- acter in the genus Homo inherited from their early hominin ancestors; (ii) statures that can be found in modern human middle-latitude pop- ulations that first appeared 1.6–1.5 Mya; and (iii) large femoral heads in some individuals, a trait that first appeared during the middle Pleistocene in Africa and Europe. The intrapopulational size variation in SH shows that the level of dimorphism was similar to modern humans (MH), but the SH hominins were less encephalized than Ne- andertals. SH shares many postcranial anatomical features with Ne- andertals. Although most of these features appear to be either plesiomorphic retentions or are of uncertain phylogenetic polarity, a few represent Neandertal apomorphies. Nevertheless, the full suite of Neandertal-derived features is not yet present in the SH popula- tion. The postcranial evidence is consistent with the hypothesis based on the cranial morphology that the SH hominins are a sister group to the later Neandertals. Comparison of the SH postcranial skeleton to other hominins suggests that the evolution of the postcranium oc- curred in a mosaic mode, both at a general and at a detailed level.

Galve (Teruel, Spain) is not a single fossil site but an ensemble of more than 50 localities with Mesozoic terrestrial vertebrate remains of Tithonian-Lower Barremian age. Galve fossil sites belong to the Maestrazgo basin (Central Iberian Range), Gaive Subbasin, and appear in four geological formations: Higueruelas Formation (Tithonian), Villar del Arzobispo Formation (upper Tithonian-middle Berriasian), El Castellar Formation (uppermost Hauterivianlowermost Barremian) and Camarillas Formation (lower Barremian). Most sites contain bony remains, but there are also paleoichnological and paleoological sites, with dinosaur and other reptilian tracks and eggshells. Mammals and dinosaurs are the best-known Gaive vertebrates, but some studies on sharks, bony fishes, amphibians, squamates and crocodiles have been published. Some groups, like turtles and pterosaurs, have not practically been studied yet. Galve is the type locality of severa1 taxa: the shark Lonchidion microselachos, the amphibian Galverpeton ibericum, the dinosaur Aragosaurus ischiaticus, the mammals Galveodon nannothus, Lavocatia alfambrensis, Eobaatar hispanicus, Parendotherium herreroi, Spalacotherium henkeli and Pocamus pepelui, and the dinosaur eggshell Macroolithus turolensis. In this paper we revise the knowledge on Galve vertebrates, and update the faunal list of its fossil sites, taking into account, for the first time, the stratigraphic distribution of the taxa.En Galve (Teruel) hay más de 50 localidades con restos de vertebrados continentales en las Formaciones Higueruelas (Titónico), Villar del Arzobispo (Titánico superior-Berriasiense medio), El Castellar (Hauteriviense terminal-Barremiense basal) y Camarillas (Barremiense inferior). Por tanto, «Galve» no es un único yacimiento de vertebrados mesozoicos, sino una localidad con numerosos yacimientos de vertebrados del intervalo Titónico-Barremiense, que geológicamente pertenecen a la Cuenca cretácica inferior del Maestrazgo (Cordillera Ibérica Central), Subcuenca de Galve. La mayor parte de los yacimientos contienen restos óseos, pero también son abundantes los yacimientos paleoicnológicos y paleoológicos. Los vertebrados mejor conocidos son los mamíferos y dinosaurios, aunque también hay estudios sobre los tiburones, peces óseos, anfibios, escamosos y cocodrilos. Algunos grupos, como tortugas y pterosaurios, permanecen prácticamente sin estudiar.

- Abstract
10.1016/j.quascirev.2014.05.031 The first migration out of Africa undertaken by the genus Homo is documented in Georgia at 1.8 Myr (Dmanisi) and some 0.4 Myr afterwards in the Middle East (¿Ubeidiya). However, the debate on when the European continent was populated for the first time remains open. The first human presence in Europe prior to the Jaramillo subchron (1.07¿0.99 Myr) is evidenced at Fuente Nueva 3 and Barranco León D (Orce) and at Sima del Elefante (Atapuerca), an occupation that seems to have continued through the Jaramillo at Gran Dolina TD3¿4 and TD5 (Atapuerca), at Vallparadís (Barcelona), and up to the Matuyama¿Brunhes boundary at Gran Dolina TD6. Even so, those who still defend a `short chronology¿ espouse an intermittent early population limited to the Mediterranean area, delaying the first occupation until after the Jaramillo. These hypotheses fail to explain what factors were behind the absence of population in Europe prior to this period, bearing in mind that there were populations of hominins at the gates of Europe between 1 and 0.5 Myr before the first archaeological record documented in Western Europe. Paleomagnetic analyses of the archaeological sites are rarely able to detect the Jaramillo subchron due to its short duration, while the radiometric dating methods (U-series/ESR) usually applied are limited in the accuracy they can achieve for the chronologies in question. These limitations make it necessary to depend on the biostratigraphy of small and large mammals to ascertain with precision the time of the first colonization of the continent. Accordingly, in the present article we discuss the chronological data from the older Iberian archaeological sites using biostratigraphic data to establish an archaeological sequence that demonstrates the

Mammals ,Middle Pleistocene ,Teruel ,Obon ,Cueva de los Huesos - Abstract
The Middle Pleistocene coincides with an important climate change, from this time ahead, the 100ky glacial cycles become a dominant feature. The opening of the landscapes, and a series of dispersal events of prairie taxa as the microtines, cricetids, ungulates and carnivores as well as Homo heidelbergensis mark this event. The rareness of fossil faunas of this age makes the Cueva de los Huesos de Obon one of the most important localities of this age in Aragon. Here we provide the first account on the Middle Pleistocene mammals from the Cueva de los Huesos, Obon, Teruel. The fossil mammalian species recovered in Obon are: Canis lupus, Vulpes vulpes, Felis sylvestris, Meles meles Hyaenidae and Carnivora indet., Stephanorhinus cf. hemitoechus, Equus sp. Gr. E. mosbachensis, Cervus elaphus priscus, Hemitragus sp. Erinaceus europaeus, Rhinolophus sp., Allocricetus bursae correzensis, Apodemus sp. This association is somewhat similar to that in the Trinchera Galería, Trinchera Dolina 8b-11 and Sima de los Huesos localities of Atapuerca

Villar del Arzobispo Formation ,Berriasian ,Tithonian ,Galve ,Dinosaurs - Abstract
The association of dinosaurs of the Villar del Arzobispo Formation in Galve (Teruel, Aragon, Spain) represents a «jurassic association» by the abundance of primitive clades like basal neosauropods and the scarcity of ornithopods. This fact could indicate the persistence of the Jurassic dinosaur faunas in this part of Laurasia, at least up to the Berriasian. Anyway the absence of stegosaurians could be interpreted as the first evidence of the turnover that would come in the Cretaceous faunas. Our data indicate that the climatic change did not suddenly affected to the dinosaurs of the Tethyan province. On the contrary, the turnover to the modern faunas took place gradually at least during the Berriasian

We report here the dromeosaurid teeth from Vallipon (Artoles Formation) in the Iberian Chain (Teruel). The teeth of Vallipon are distinguished from other curved theropod teeth by their strong lateral compression, by the shape of their denticles and by small size. Generally denticles appear only the distal carinae of the teeth. Nevertheless some teeth have denticles on both anterior and posterior margins, although the mesial denticles are much smaller than the distal denticles

Iberomys huescarensis ,Atapuerca ,Trinchera Dolina ,Iberomys brecciensis ,Lower Pleistocene - Abstract
The Iberomys lineage is represented by the species I. huescarensis (Ruiz Bustos, 1988), at the lower levels (TD3 to lower TD8) of Trinchera Dolina (Sierra de Atapuerca, Burgos), and not by I. brecciensis Ciebel, 1847 as stated previously. Both species mainly differ in the communication of triangles T4 and T5 of the first lower molar dental pattern, broad in I. huescarensis and narrow in I. brecciensis. I. huescarensis is the ancestral species of the I. brecciensis-cabrerae lineage, and characterizes the late Lower Pleistocene and the transition Lower-Middle Pleistocene in the Iberian Peninsula

The Iberomys lineage is represented by the species I. huescarensis (Ruiz Bustos, 1988), at the lower levels (TD3 to lower TD8) of Trinchera Dolina (Sierra de Atapuerca, Burgos), and not by I. brecciensis Ciebel, 1847 as stated previously. Both species mainly differ in the communication of triangles T4 and T5 of the first lower molar dental pattern, broad in I. huescarensis and narrow in I. brecciensis. I. huescarensis is the ancestral species of the I. brecciensis-cabrerae lineage, and characterizes the late Lower Pleistocene and the transition Lower-Middle Pleistocene in the Iberian Peninsula

- Abstract
The Sciuridae are the family of rodents that comprises all extant and fossil squirrels. In the Ramblian and especially in the Aragonian of the Tertiary basin of Calatayud-Montalbán (Aragón, Spain) the remains of Sciuridae are relatively abundant. A major problem solved in this paper is the distinction of Ml and M2, both in the upper and the lower dentition. Traditionally, in the literature these elements are treated as a unit Ml,2. We managed to separate them, on the basis of the study of material of two extant species, Atlantoxerus getulus and Sciurus vulgaris. In our study of the fossil Sciuridae from the Calatayud-Montalbán Basin 9 species were recognized, belonging to 6 genera: Heteroxerus rubricati, H. grivensis, Atlantoxerus idubedensis sp. nov., A. blacki, Aragoxerus ignis, Spermophilinus besana sp. nov., S. bredai, Freudenthalia daamsi sp. nov. y Palaeosciurus feignouxi. Aragoxerus and Freudenthalia are new genera. Atlantoxerus idubedensis sp. nov. is a small Atlantoxerus, similar to primitive Heteroxerus, and characterized by a reduced or absent anterior cingulum in M1, M2 and M3. Spermophilinus besana sp. nov. is the smallest Spermophilinus species known so far. In the lower teeth the anterolophid is separated from the protoconid by a deep furrow, and the entoconid is reduced or absent. Aragoxerus gen. nov. (tribe Xerini) contains only one species, A. ignis, formerly assigned to Heteroxerus. Although Aragoxerus is quite similar to Heteroxerus, its smaller size, simple dental pattern, absence of metaconule and anterior cingulum, and the lack of accessory ornamentations permit us to distinguish it as a separate genus. Freudenthalia gen. nov. is a monospecific genus of uncertain systematic position, tentatively placed in the tribe Sciurini. Freudenthalia daamsi sp. nov. is the only species of this genus. It is characterized by a metaloph completely fused to the protocone, a loop-shaped metaconule, and the absence of the entolophid. Within the genus Heteroxerus two pairs of names are synonimized: H. vireti is a synonym of H. ru

En aquest treball han estat estudiades nombroses restes de lagomorfs (O. Lagomorpha, Cl. Mammalia) de diversos jaciments del Pliocè i Pleistocè europeus, com Zújar - 11 (Granada), Casablanca 1 (Castelló), Perrier (França), Valdarno (Itàlia), Barranco León 5 i Fuente Nueva 3 (Granada), Cueva Victoria (Murcia), Sima del Elefante 9 (Atapuerca), Dmanisi (Geòrgia), Cova del Toll i El Carmel (Barcelona). S'ha prestat especial interès en la família Leporidae, que és la que presenta més problemàtiques en la sistemàtica. Abans de dur a terme l'estudi sistemàtic dels fòssils, ha estat necessari reconèixer els principals caràcters morfològics que diferencien els taxons de lepòrids actuals que viuen en la regió mediterrània occidental. Aquest estudi s'ha centrat bàsicament en l'esquelet i, especialment, en el tercer premolar inferior. Així, d'una banda, les relacions entre els paràmetres biomètrics han permès diferenciar els gèneres Oryctolagus i Lepus; d'altra banda, a partir de l'anàlisi morfomètrica del P3 que s'ha efectuat mitjançant landmarks i transformades de Fourier, també ha sigut possible discriminar entre ambdós gèneres. D'aquesta manera, a partir d'aquests dos estudis dels lepòrids actuals s'ha realitzat una assignació taxonòmica de les restes fòssils. Pel que fa als ocotònids (Fam. Ochotonidae), s'ha identificat Prolagus michauxi a Zújar (sent la resta més moderna d'aquesta espècie), Prolagus calpensis a Casablanca i Cueva Victoria, Prolagus sp. a Barranco León 5, i Ochotona sp. a Dmanisi. Respecte els lepòrids, s'ha identificat la presència d'un Leporidae indet. a Perpignan (França), tot i que probablement es tracti de Trischizolagus o Hypolagus; d'Oryctolagus sp. a Zújar 11, Casablanca, Barranco León 5, Fuente Nueva 3 i Sima del Elefante TE9; d'Oryctolagus lacosti a Perrier (França) i Valdarno (Itàlia); d'Oryctolagus giberti (nova espècie per la ciència) a Cueva Victoria i El Carmel; d'O. cuniculus a la Cova del Toll, i de Lepus sp. en el jaciment de Sima del Elefante TE9. Cap resta fòssil clarament atribuïble a O. cuniculus ha estat identificada en el Pleistocè inferior, fet que no concorda amb els resultats dels estudis moleculars. D'altra banda, la presència de veritables llebres ja en el Pleistocè inferior a Europa occidental, fins ara en discussió, queda confirmada a partir del material de Sima del Elefante TE9., Fossil lagomorphs (Lagomorpha, Mammalia) are common in Pliocene and Pleistocene European sites but they have been understudied until now. Fossil remains are craneal and postcraneal bones, teeth being particularly abundant, but the high morphological variability of this group makes taxonomic identification difficult. To solve this main obstacle, a morphologic study of Recent and fossil lagomorphs, paying special attention to the morphometry of the third lower premolar of modern Leporids from the Western Mediterranean area has been carried out. Landmark and elliptic Fourier analyses are applied for the first time to the study of this group. So, the results allow to clearly discriminate the leporid genera Oryctolagus and Lepus, and are very useful for the determination of fossil remains. Studied material was either directly sampled in the outcrops or belongs to historical collections housed in Museums. The main considered localities are Perrier (France), Valdarno (Italy), Dmanisi (Georgia), Zújar 11, Casablanca, Barranco León and Fuente Nueva, Cueva Victoria, Sima del Elefante, Cova del Toll and El Carmel (Spain). The following taxa have been identified: Prolagus sp., Prolagus michauxi, Prolagus calpensis, and Ochotona sp. (Ochotonidae); and Oryctolagus sp., Oryctolagus lacosti, Oryctolagus giberti (new species), Oryctolagus cuniculus, and Lepus sp. (Leporidae). Oryctolagus giberti shows several intermediate characters between O. laynensis, the first known representative of the genus, and the modern European rabbit (O. cuniculus), turning it in a firm candidate to occupy a phylogenetic place between these two species. The remains of P. michauxi of Zújar (upper Pliocene) represent the most modern record of this species known until now, and the abundant fossils of Lepus sp. from Sima del Elefante confirms the early presence of this genus in the Lower Pleistocene of Europe.

- Abstract
The Iberian Peninsula is a key region for unraveling human settlement histories of Eurasia during the period spanning the decline of Neandertals and the emergence of anatomically modern humans (AMH). There is no evidence of human occupation in central Iberia after the disappearance of Neandertals ~42,000 years ago until approximately 26,000 years ago, rendering the region "nobody's land" during the Aurignacian period. The Abrigo de la Malia provides irrefutable evidence of human settlements dating back to 36,200 to 31,760 calibrated years before the present (cal B.P.) This site also records additional levels of occupation around 32,420 to 26,260 cal B.P., suggesting repeated settlement of this territory. Our multiproxy examination identifies a change in climate trending toward colder and more arid conditions. However, this climatic deterioration does not appear to have affected AMH subsistence strategies or their capacity to inhabit this region. These findings reveal the ability of AMH groups to colonize regions hitherto considered uninhabitable, reopening the debate on early Upper Paleolithic population dynamics of southwestern Europe.

- Abstract
Rodents are a very useful tool in reconstructing the environment of the past, especially owing to their rapid response to climate change, their small home range, and their restricted habitat requirements. They are a highly diverse group of mammals, which have high reproduction rates and as a result can evolve rapidly. The abundance of their microfossil remains in archaeological and paleontological sites permits robust statistical analyses to reconstruct the past climate and environment. Recently, a number of studies have affirmed the need to deepen the climatic characterization of the European Quaternary, the Middle Pleistocene being an important stage for ascertaining how our hominin ancestors lived. The aim of this study is to characterize the climatic conditions in which hominins lived in southwestern Mediterranean Europe during the Middle Pleistocene. To reconstruct these climatic conditions, we apply the bioclimatic model to rodent assemblages from Middle Pleistocene sites with human remains (Caune de l'Arago, Sima de los Huesos, Aroeira cave, Visogliano, Trinchera Galeria, and Mollet cave). Based on the percentage distribution of the species in different climate types and applying multiple linear regressions, we estimated the mean annual temperature, the mean temperature of the coldest month, and the mean temperature of the warmest month. We compared these estimates with data collected over the last 30 years from nearby meteorological stations to obtain the differences with current climate and observe the fluctuations. The climatic conditions obtained from the results of this study show that, while in Iberia mild climatic condition prevailed, in southern France and northeastern Italy harsher weather conditions were indicated., Competing Interests: Declaration of competing interest The author declares that there is no conflict of interest., (Copyright © 2020 Elsevier Ltd.

- Abstract
We have developed a protocol for reconstructing 3D models of the skulls of extinct species of small mammals. For the first time, the reconstruction uses fragments of fossils from a mixture of different specimens and from related extant species. We use free software and commercial computers to make the process reproducible and usable for the scientific community. We present a semi-quantitative protocol to face the problem of making 3D reconstructions of fossil species that are incomplete in the fossil record and/or represented by a mixture of different individuals, as usually occurs with small vertebrates. Therefore this approach is useful when no complete skull is available. The protocol combines the use of microCT scan technology with a subsequent computer treatment using different software tools for 3D reconstruction from microCT and 3D design and printing (e.g. Fiji, SPIERS, Meshlab, Meshmixer) in a defined order. This kind of free and relatively simple software, plus the detailed description, makes this protocol practicable for researchers who do not necessarily have great deal of experience in working with 3D. As an example, we have performed virtual reconstructions of the skulls of two species of insectivore small mammals (Eulipotyphla): Beremendia fissidens and Dolinasorex glyphodon. The resulting skulls, plus models of the extant shrews Blarina brevicauda, Neomys fodiens, Crocidura russula and Sorex coronatus, make it possible to compare characteristics that can only be observed by means of microCT 3D reconstructions, and given the characteristics of the material, using this protocol. Among the characters we can compare are the position of the mandibles, the spatial relations among all the teeth, the shape of the snout and, in general, all parameters related with the anatomy of the rostrum. Moreover, these reconstructions can be used in different types of context: for anatomical purposes, especially to see internal features or characteristics at whole-skull scale, for bioengineering, animation, or other techniques that need a digital model., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Introduction and Objectives: Although the Iberian Peninsula is a key area for understanding the Middle to Upper Paleolithic transition and the demise of the Neandertals, valuable evidence for these debates remains scarce and problematic in its interior regions. Sparse data supporting a late Neandertal persistence in the Iberian interior have been recently refuted and hence new evidence is needed to build new models on the timing and causes of Neandertal disappearance in inland Iberia and the whole peninsula. In this study we provide new evidence from Los Casares, a cave located in the highlands of the Spanish Meseta, where a Neandertal-associated Middle Paleolithic site was discovered and first excavated in the 1960's. Our main objective is twofold: (1) provide an updated geoarcheological, paleoenvironmental and chronological framework for this site, and (2) discuss obtained results in the context of the time and nature of the last Neandertal presence in Iberia., Methods: We conducted new fieldwork in an interior chamber of Los Casares cave named 'Seno A'. Our methods included micromorphology, sedimentology, radiocarbon dating, Uranium/Thorium dating, palinology, microfaunal analysis, anthracology, phytolith analysis, archeozoology and lithic technology. Here we present results on site formation processes, paleoenvironment and the chronological setting of the Neandertal occupation at Los Casares cave-Seno A., Results and Discussion: The sediment sequence reveals a mostly in situ archeological deposit containing evidence of both Neandertal activity and carnivore action in level c, dated to 44,899-42,175 calendar years ago. This occupation occurred during a warm and humid interval of Marine Isotopic Stage 3, probably correlating with Greenland Interstadial 11, representing one of the latest occurrences of Neandertals in the Iberian interior. However, overlying layer b records a deterioration of local environments, thus providing a plausible explanation for the abandonment of the site, and perhaps for the total disappearance of Neandertals of the highlands of inland Iberia during subsequent Greenland Stadials 11 or 10, or even Heinrich Stadial 4. Since layer b provided very few signs of human activity and no reliable chronometric results, and given the scarce chronostratigrapic evidence recorded so far for this period in interior Iberia, this can only be taken as a working hypothesis to be tested with future research. Meanwhile, 42,000 calendar years ago remains the most plausible date for the abandonment of interior Iberia by Neandertals, possibly due to climate deterioration. Currently, a later survival of this human species in Iberia is limited to the southern coasts.

- Abstract
Current knowledge of the evolution of the postcranial skeleton in the genus Homo is hampered by a geographically and chronologically scattered fossil record. Here we present a complete characterization of the postcranium of the middle Pleistocene paleodeme from the Sima de los Huesos (SH) and its paleobiological implications. The SH hominins show the following: (i) wide bodies, a plesiomorphic character in the genus Homo inherited from their early hominin ancestors; (ii) statures that can be found in modern human middle-latitude populations that first appeared 1.6-1.5 Mya; and (iii) large femoral heads in some individuals, a trait that first appeared during the middle Pleistocene in Africa and Europe. The intrapopulational size variation in SH shows that the level of dimorphism was similar to modern humans (MH), but the SH hominins were less encephalized than Neandertals. SH shares many postcranial anatomical features with Neandertals. Although most of these features appear to be either plesiomorphic retentions or are of uncertain phylogenetic polarity, a few represent Neandertal apomorphies. Nevertheless, the full suite of Neandertal-derived features is not yet present in the SH population. The postcranial evidence is consistent with the hypothesis based on the cranial morphology that the SH hominins are a sister group to the later Neandertals. Comparison of the SH postcranial skeleton to other hominins suggests that the evolution of the postcranium occurred in a mosaic mode, both at a general and at a detailed level.

- Abstract
The allometric-constraint hypothesis states that evolutionary divergence of morphological traits is restricted by integrated growth regulation. In this study, we test this hypothesis on a time-calibrated and well-documented palaeontological sequence of dental measurements on the Pleistocene arvicoline rodent species Mimomys savini from the Iberian Peninsula. Based on 507 specimens representing nine populations regularly spaced over 600 000 years, we compare static (within-population) and evolutionary (among-population) allometric slopes between the width and the length of the first lower molar. We find that the static allometric slope remains evolutionary stable and predicts the evolutionary allometry quite well. These results support the hypothesis that the macroevolutionary divergence of molar traits is constrained by static allometric relationships., (© 2014 The Author(s) Published by the Royal Society.

- Abstract
Eating habits of Panthera pardus are well known. When there are caves in its territory, prey accumulates inside them. This helps to prevent its kill from being stolen by other predators like hyenas. Although the leopard is an accumulator of bones in caves, few studies have been conducted on existing lairs. There are, however, examples of fossil vertebrate sites whose main collecting agent is the leopard. During the Late Pleistocene, the leopard was a common carnivore in European faunal associations. Here we present a new locality of Quaternary mammals with a scarce human presence, the cave of Los Rincones (province of Zaragoza, Spain); we show the leopard to be the main accumulator of the bones in the cave, while there are no interactions between humans and leopards. For this purpose, a taphonomic analysis is performed on different bone-layers of the cave.

- Abstract
The transition from the Middle Palaeolithic (Mousterian) to the Upper Palaeolithic (Aurignacian) has been one of the prominent themes in the archaeology of the European Palaeolithic for more than 20 years. One of the most controversial questions concerning this period is the extinction of the Neanderthals and their replacement by modern humans. In this context, Cueva del Conde, located in the northern part of the Iberian Peninsula, is an archaeo-palaeontological site that records the Mousterian to Aurignacian transition. It has been excavated since the beginning of the 20th century, first by the Conde de la Vega del Sella and systematically by a team from the University of Oviedo since 2001. Three main zones have been identified: the External Zone, dated to approximately 39,110 ± 520 BP (level N104); the Entrance Platform, dated between 38,250 ± 390 BP and 34,730 ± 500 BP; and Gallery A with a radiocarbon date of approximately 31,540 ± 400 BP (level N2a2). The small-vertebrate assemblages recovered from the water-screening of all sediment from the excavation campaigns represent at least 21 small mammal, amphibian and squamate taxa. The small-vertebrate associations in the three zones suggest a patchy landscape, dominated by humid meadows and woodland areas with the existence of water in the vicinity of the cave. The climate shows a more continental pattern during the Mousterian, though it was milder during the Aurignacian. The small vertebrates of the Cueva del Conde Mousterian and Aurignacian levels suggest a climate that differed from modern day temperatures, between -1.1 and -4.4 °C (mean annual temperature), placing these assemblages during Interstadials 9 to 7 (Is9 to 7)., (Copyright © 2011 Elsevier Ltd.

- Abstract
The Gran Dolina cave site is famous for having delivered some of the oldest hominin remains of Western Europe (Homo antecessor, ca. 960 ka). Moreover, the evidence of lithic industries throughout the long vertical section suggests occupation on the part of hominins from the latest early Pleistocene (levels TD3/4, TD5, and TD6) to the late middle Pleistocene (level TD10). The Gran Dolina Sondeo Sur (TDS) has furnished a great number of small-vertebrate remains; among them some 40,000 bones are attributed to amphibians and squamates. Although they do not differ specifically from the extant herpetofauna of the Iberian Peninsula, the overlap of their current distribution areas (= mutual climatic range method) in Spain can provide mean annual temperatures (MAT), the mean temperatures of the coldest (MTC) and warmest (MTW) months, and mean annual precipitation (MAP) estimations for each sub-level, and their change can be studied throughout the sequence. Results from the squamate and amphibian study indicate that during hominin occupation the MAT (10-13 degrees C) was always slightly warmer than at present in the vicinity of the Gran Dolina Cave, and the MAP (800-1000mm) was greater than today in the Burgos area. Climatic differences between "glacial" and "interglacial" phases are poorly marked. Summer temperatures (MTW) show stronger oscillations than winter temperatures (MTC), but seasonality remains almost unchanged throughout the sequence. These results are compared with those for large mammals, small mammals, and pollen analysis, giving a scenario for the palaeoclimatic conditions that occurred during the early to middle Pleistocene in Atapuerca, and hence a scenario for the hominins that once lived in the Sierra de Atapuerca.

- Abstract
The earliest hominin occupation of Europe is one of the most debated topics in palaeoanthropology. However, the purportedly oldest of the Early Pleistocene sites in Eurasia lack precise age control and contain stone tools rather than human fossil remains. Here we report the discovery of a human mandible associated with an assemblage of Mode 1 lithic tools and faunal remains bearing traces of hominin processing, in stratigraphic level TE9 at the site of the Sima del Elefante, Atapuerca, Spain. Level TE9 has been dated to the Early Pleistocene (approximately 1.2-1.1 Myr), based on a combination of palaeomagnetism, cosmogenic nuclides and biostratigraphy. The Sima del Elefante site thus emerges as the oldest, most accurately dated record of human occupation in Europe, to our knowledge. The study of the human mandible suggests that the first settlement of Western Europe could be related to an early demographic expansion out of Africa. The new evidence, with previous findings in other Atapuerca sites (level TD6 from Gran Dolina), also suggests that a speciation event occurred in this extreme area of the Eurasian continent during the Early Pleistocene, initiating the hominin lineage represented by the TE9 and TD6 hominins.

- Abstract
Level TD6 of the Trinchera Dolina Section in the railway cutting of the Sierre de Atapuerca (Trinchera del Ferrocarril) has yielded a rich small mammal assemblage (26 species) in association with fossil human remains of Homo antecessor. The arvicolids of TD6 are identified as: Mimomys savini, Microtus seseae, Stenocranius gregaloides, Terricola arvalidens, Iberomys huescarensis, Allophaiomys chalinei, and Pliomys episcopalis. The rodent association also includes large rodents (i.e., Castor fiber, Marmota sp., and Hystrix refossa) and the small Allocricetus sp., Eliomys helleri, Micromys minutus, and Apodemus aff. flavicollis. The small vertebrate remains also include Insectivora (Beremendia fissidens, Sorex sp, Neomys sp., Crocidura sp., Galemys sp., Talpa sp., Erinaceus sp.), Chiroptera (Miniopterus schreibersii, Myotis sp., Rhinolophus sp.), and Lagomorpha (Oryctolagus sp., Lepus sp.), as well as lizards, birds and amphibians. The H. antecessor remains are derived from a 15 cm thick layer at the top of TD6 (TD6-T36-43), where A. chalinei, H. refossa and Marmota sp. do not occur. The paleomagnetic Matuyama/Brunhes boundary is found in the overlying level TD7 of the Gran Dolina Section. On the basis of the arvicolids, TD6 can be referred to the Biharian biochron. The Matuyama/Brunhes boundary is fixed in the late Biharian (Microtus-Mimomys rodent Superzone). The species M. savini (without M. pusillus), as well as the evolutionary stage of Microtus s.l., are characteristic of the Late Biharian. The evolutionary level of the species M. savini, T. arvalidens, S. gregaloides indicates that TD6 is older than West Runton (type Cromerian). In the Trinchera Dolina Section we are able to calibrate, for the first time, the evolutionary level of important biochronological markers with magnetostratigraphy. We propose that a radiation of Microtus s.l., along with the first appearance of primitive S. gregaloides, T. arvalidens and Iberomys, took place just before the Matuyama/Brunhes boundary. These species can be considered as characteristic elements of early Pleistocene faunas., (Copyright 1999 Academic Press.)

- Abstract
A small collection of rodents from Sima de los Huesos helps to clarify the stratigraphic position of this famous human locality. The presence of Allocricetus bursae and Pliomys lenki relictus and the size of A. bursae, Apodemus sylvaticus and Eliomys quercinus suggest a Middle Pleistocene age (Saalian) to the Clays where humans have been found.
