New Neandertal remains from Cova Negra (Valencia, Spain)

New Neandertal fossils from the Mousterian site of Cova Negra in the Valencia region of Spain are described, and a comprehensive study of the entire human fossil sample is provided. The new specimens significantly augment the sample of human remains from this site and make Cova Negra one of the richest human paleontological sites on the Iberian Peninsula. The new specimens include cranial and postcranial elements from immature individuals and provide an opportunity to study the ontogenetic appearance of adult Neandertal characteristics in this Pleistocene population. Children younger than 10 years of age constitute four of the seven minimum number of individuals in the sample, and this relative abundance of children at Cova Negra is similar that in to other Neandertal sites in Europe and southwest Asia. The recognition of diagnostic Neandertal features in several of the specimens, as well as their western European context and late Pleistocene age, suggests that all the human remains from Cova Negra represent Neandertals. The archaeological evidence from Cova Negra indicates sporadic, short-term occupations of the site, suggesting a high degree of mobility among Neandertals.     

Fossil remains of Macaca sylvanus florentina (Cocchi, 1872) (Primates, Cercopithecidae) from the Early Pleistocene of Quibas (Murcia, Spain)

The macaque material from the Early Pleistocene site of Quibas (Albanilla, Murcia, Spain), including dentognathic remains, isolated teeth and some postcranial bone fragments, is described. Both metrically and morphologically, this sample must be attributed to Macaca sylvanus (the Barbary macaque). This species is currently distributed through North Africa and Gibraltar, but was much more widely distributed during the Plio-Pleistocene, being represented by several European fossil subspecies. Metrical comparisons of dental size and proportions between extant M. s. sylvanus and fossil Macaca sylvanus florentina from the type locality and other Italian sites are undertaken, in order to classify the remains from Quibas at the subspecies level. The results show that the Quibas sample not only fits the range of variation of M. s. florentina from the type locality, but also differs from the extant Barbary macaque condition in several regards. This permits us to formally attribute the material from Quibas to M. s. florentina. The material described in this paper therefore significantly improves the knowledge of this fossil taxon, particularly regarding the upper dentition, and further confirms the taxonomic distinctiveness of this extinct taxon at the subspecies rank. Taken as a whole, M. s. florentina largely overlaps in dental dimensions with M. s. sylvanus, but differs from the latter by displaying (on average): (1) absolutely longer upper molars (especially M¹ and M³); (2) relatively wider upper molars (especially M¹ and M²); (3) longer M³ as compared with the M²; (4) absolutely longer M₁ and M₃; and (5) relatively narrower M₃.     

Presence of Hemitragus aff. cedrensis (Mammalia, Bovidae) in the Iberian Peninsula: Biochronological and biogeographical implications of its discovery at Bolomor Cave (Valencia, Spain)

The discovery of new material in Late Pleistocene levels at Bolomor Cave (Valencia, Spain) raises some questions about the presence of the most ancient record of Hemitragus cedrensis in the peninsula, and its dispersal out of Provence. The morphology and dimensions of some lower teeth confirm the identification of H. aff. cedrensis. Moreover, it presents strong similarities, both morphological and metrical, with the specimens from Caune de l’Arago and bau de l’Aubesier (end of OIS 7 to OIS 5e) rather than with the population from the eponymous locality. The data suggest a dispersal event out of Provence towards the Iberian Peninsula during the Eemian. This dispersal was not stopped by natural barriers such as large rivers, or mountains. The results presented here confirm the biochronological interest of the genus Hemitragus for the Late Pleistocene in Mediterranean Europe.     

The Azilian man from Los Azules Cave I (Cangas de Onis,Oviedo, Spain)

The author analyzes in this study the human skeleton found in the Azilian Grave of Los Azules Cave I (Asturias, NW of Spain), dated by C-14 between 7480 and 7590 B. C. It was diagnosed as an adult male, having a general strong robustness and high stature, as well as a congenital fusion of the right talus bones and, probably, bilateral claw foot. The comparison to the last Upper Paleolithic, the Epipaleolithic and the Mesolithic Human remains from Western Europe showed the similarity of Los Azules I Man to the robust Cromagnoids from these periods.     

Matuyama-age lithic tools from the Sima del Elefante site, Atapuerca (northern Spain)

Paleomagnetic results obtained from the sedimentary fill at the Sima del Elefante site in Atapuerca, Spain, reveal a geomagnetic reversal, interpreted as the Matuyama-Brunhes boundary (0.78 Ma). The uppermost lithostratigraphic units (E17 through E19), which contain Mode II and III archaeological assemblages, display normal polarity magnetization, whereas the six lowermost units (E9 through E16) yield negative latitudinal virtual geomagnetic pole positions. Units E9 through E13, all of which display reverse magnetic polarity, contain Mode I (Oldowan) lithic tools, testifying to the presence of humans in the early Pleistocene (0.78-1.77 Ma).     

A new species of Anthemis L. (Asteraceae) from Central Spain

CARRETERO, J. L., 1992. A new species of Anthemis L. (Asteraceae) from Central Spain. A new species of Anthemis is described from the eastern Toledo Mountains. The morphological relationships to other taxa, as well as the chorology and ecology of the new species are presented.     

Newly recognized Pleistocene human teeth from Tabun Cave, Israel

Seven human teeth from Tabun Cave, Israel, curated at the Natural History Museum London since 1955, are of uncertain provenance and identity. They are all from the upper dentition, without duplications, and are characterized by a similar preservation. The Catalogue of Fossil Hominids (1975) suggested that they might have derived from Tabun Layer A (Bronze Age to Recent). However, one of us (AC) noted some distinctive features of these teeth that warranted further study. They are here assigned to a single individual, Tabun BC7. Their morphology and metrics were then compared with the frequency of Late Pleistocene and Early Holocene groups from Europe, North Africa and Middle East. A fragment of the right M3 crown of Tabun BC7 was removed for ESR and U-analysis, and it was determined that only samples from Layer B have similar dose values. Using the sediment dose values of layer B, preliminary age estimates of 82 +/- 14 ka (early U-uptake) and 92+/-18 ka (linear uptake) were obtained. U-series disequilibrium determined from other samples attributed to Layer B resulted in a U-uptake history close to linear uptake, giving a very comparable age estimate of 90(+30)(-16) ka. The dose value previously obtained on an enamel fragment from the Tabun C1 dentition is nearly double the value measured for BC7, and tentative age estimates for C1 were in the range of 143+/-37 ka. However, due to uncertainties in the exact provenance of the human fossils, we cannot confirm that C1 is older than the new tooth sampled here, and both C1 and BC7 can be attributed to Layer B on chronological grounds. On the basis of chronology, dental morphology and metrics, the specimen named Tabun BC7 was identified as a probable Neanderthal.     

Dental remains from Dmanisi (Republic of Georgia): morphological analysis and comparative study

The systematic excavation of the Dmanisi site (Republic of Georgia) has provided the earliest evidence of hominins outside Africa, dating back to ca. 1.8Ma. The analysis of the hominin remains has mainly focused on the morphology of the crania and mandibles. We present the first detailed morphological analysis and comparison of the Dmanisi teeth. The dental evidence from Dmanisi shows a unique combination of primitive and derived traits. In general, although the Dmanisi dental fossils show primitive morphology that resembles that seen in Australopithecus and H. habilis, they also display some derived characteristics, particularly in relation to dental reduction, resembling that seen in the dentition of H. erectus from the Far East.     

Small and large game: Human use of diverse faunal resources at Level IV of Bolomor Cave (Valencia,Spain)

Within the framework of nutritional ecology, subsistence diversification is achieved by adding different species to a diet, but explanations for this diversification vary. In the Broad Spectrum Revolution approach, explanations include demographic, ecological, nutritional and technological factors, as well as the mobility of hunter-gatherer groups. The origin of small animal assemblages is a key issue underlying this debate, as these were an important food resource for several non-human predators (diurnal and nocturnal birds of prey and terrestrial carnivores). To establish the genesis of these accumulations, it is important to analyse the anatomical and age profiles of the animals, the bone breakage patterns and the bone surface modifications. With this aim, we present data from the Level IV faunal assemblage of Bolomor Cave (Valencia, Spain). Level IV, corresponding to MIS 5e, shows human use not only of small animals but also of large- and small-sized carnivores in addition to ungulates. Anthropogenic evidence includes cut-marks, intentional bone breakage, burning patterns and human tooth-marks. The utilisation of other less frequent animals could be related to a generalist human behaviour based on the exploitation of a broad range of prey, and could also be associated with an early diversification of the human diet in this locality. This study aims to provide data concerning human consumption of small prey, to establish the processing sequence both of large/medium and small animals and to contribute to the knowledge of human subsistence strategies in the European Middle Palaeolithic.     

Human remains from Blombos Cave, South Africa: (1997-1998 excavations)

The Middle Stone Age (MSA) layers at Blombos Cave contain abundant bifacial Still Bay points, formal and ad hoc bone artefacts, and an intentionally incised bone piece. These artefacts add weight to arguments that some aspects of modern human behavior developed earlier in sub-Saharan Africa than elsewhere. Four human teeth were recovered from the MSA strata at Blombos during the 1997-1998 excavations. Two are heavily worn deciduous teeth, and two are incomplete permanent premolar crowns. The Blombos di(1)is comparatively large in relation to modern African homologues, falling within the lower part of the observed Neandertal range. The dm(1)and P(3)are comparable to modern teeth and smaller than most Neandertal crowns. The premolars preserve horizontal circum-cervical striae that suggest palliative toothpick use. The di(1)evinces labial scratches that resemble neither the "cutmarks" that have been observed on Neandertal incisors, nor the striae that have been recorded on modern human teeth.     

New analysis of the Pleistocene carnivores from Petralona Cave (Macedonia, Greece) based on the Collection of the Thessaloniki Aristotle University

New taxonomic study of the “old collection” of Carnivora from Petralona Cave, associated to the well-known hominid skull, housed in the Geology School of the Thessaloniki Aristotle University since 1960, revealed 11 species (Canis arnensis, Lycaon lycaonoides, Vulpes praeglacialis, Ursus deningeri, U. spelaeus, U. arctos, Pliocrocuta perrieri, Pachycrocuta brevirostris, Crocuta crocuta, Panthera leo spelaea, and Felis silvestris), which are described in detail. The species composition is typical of the eastern part of the European Mediterranean and may be divided into three biostratigraphic assemblages: early Middle Pleistocene, late Middle Pleistocene and Late Pleistocene.     

Microfaunal remains at Middle Pleistocene Qesem Cave, Israel: Preliminary results on small vertebrates, environment and biostratigraphy

Preliminary results of the investigation of the microfauna at the Acheulo-Yabrudian Middle Pleistocene site of Qesem Cave, Israel, are presented. Thus far the assemblage includes ca. 10,000 bone and tooth fragments, of which 50% could be identified to the generic and some hundreds to the species level. Based on the current material, the fauna includes the following squamate reptiles: Laudakia sp., Chamaeleo sp., Gekkonidae indet., Lacertidae indet., Scincidae indet., Pseudopus sp., Varanus sp., Colubroidea indet. (at least three species) and micromammals: Suncus etruscus, Crocidura cf. leucodon, Crocidurinae indet. (large form), Chiroptera indet., Sciurus cf. anomalus, Cricetulus cf. migratorius, Microtus guentheri, Nannospalax ehrenbergi, Dipodillus cf. dasyurus, Meriones cf. tristrami, Gerbillidae indet., Mus cf. musculus, Apodemus cf. flavicollis. These results suggest that the fauna includes only taxa that occur recently in the territory of Israel. The ecological preferences of the nearest living relatives of the recorded taxa allow us to infer a paleoenvironment with a mosaic of open and woodland habitats. However, comparing the lower with the upper levels of the microfauna-bearing profile, a slight shift towards more wooded conditions might be detectable. Biostratigraphical inferences from the recorded micromammal taxa cover a rather wide age range, whereas the radiometric (U-series and preliminary TL) dating enable a provisionally estimated date for the microfauna-bearing levels at 360-300 ka. Detailed morphometric comparisons with material from other sites in the region are necessary and may yet provide further insights.     

A tall-spined ornithopod dinosaur from the Early Cretaceous of Salas de los Infantes (Burgos, Spain)

A tall-spined ornithopod dinosaur from the Pinilla de los Moros Formation (Upper Hauterivian-Lower Barremian) of Salas de los Infantes (Burgos, Spain) is described. The material consists of seven associated axial remains, including five middle dorsal vertebrae, a fragmentary neural spine and a dorsal rib, from a single medium-sized individual. This material was previously referred to Iguanodon cf. fittoni. It is characterised by having a high dorsal neurapophysis that is approximately 4.5 times the height of the centrum. The elongation and vertical orientation of the dorsal neural spines allow it to be distinguished from other ornithopods from the Wealden of Europe, including Hypselospinus and Barilium from the Valanginian, and Iguanodon and Mantellisaurus from the Barremian-Aptian. The material is here referred to Iguanodontia indet. because it is so incomplete, but it is potentially a distinct taxon. Among the ornithopods, only Ouranosaurus and the hadrosaurid Hypacrosaurus possess higher dorsal neural spines.     

Pleistocene paleoenvironmental evolution at continental middle latitude inferred from carbon and oxygen stable isotope analysis of ostracodes from the Guadix-Baza Basin (Granada, SE Spain)

A representative paleoenvironmental reconstruction of continental middle latitude from ca. 2 my to the upper part of Middle Pleistocene (279 ± 77 ky) was obtained from the carbon and oxygen stable isotopes analyzed in ostracode shells (Cyprideis torosa) recovered in the Guadix-Baza Basin (SE Spain), an intramontaneous closed depression filled by alluvial and lacustrine sediments. This study was performed along a 356-m-thick composite section, dated previously by paleomagnetism and the amino acid racemization method. δ¹³C and δ¹⁸O profiles reflected changes in temperature, the evaporation/infill ratio in the water bodies and the amount of rain. δ¹³C is also affected by changes in plant biomass: periods with high δ¹³C and δ¹⁸O values are associated with warm and dry regimes, and with less vegetation, which, in some cases, coincide with the development of displacive gypsum crystals, whereas low δ¹³C and δ¹⁸O values correlate with cold and humid episodes, which cause more vegetation biomass and, therefore, increasing the input of isotopically light carbon. Intermediate δ¹⁸O values are linked to temperate dry or humid episodes when they coincide with high or low δ¹³C values, respectively. 86 paleoclimatic events were distinguished in the Pleistocene record from the δ¹³C and δ¹⁸O profiles. From both the statistical analysis of the geochemical data and the geological observations, four Cold and Humid Long Periods (low δ¹⁸O) and four Warm and Dry Long Periods (high δ¹⁸O) were defined. This differs with respect to the paleoclimatological behavior established for the Northern Hemisphere where during cold periods (glacial), no water was available while permafrost conditions persisted, whereas in warm episodes (interglacial), higher precipitation rates occurred. Good correspondences between the Guadix-Baza Basin paleoclimatic record and a marine oxygen-isotope sequence, two continental cores and other long Mediterranean paleoenvironmental records (pollen sequences from Israel) were found, which suggested that climate changes in the Guadix-Baza Basin were in tune with global climatic changes.     

Several different strategies for obtaining animal resources in the late Middle Pleistocene: The case of level XII at Bolomor Cave (Valencia,Spain)

Bolomor Cave, located in Tavernes de la Valldigna (Valencia, Spain), contains a sedimentary deposit composed of seventeen stratigraphic levels ranging from MIS 9 to MIS 5e. This extensive sequence allows us to ask different questions about how the human groups of this chronological period related to their environment. We report several different strategies by which animal resources were obtained from level XII faunal assemblage (MIS 6). These practices range from scavenging to the complex hunting techniques, such as multiple predation. This practice is inferred in the case of horses (Equus ferus) on the basis of: (1) the proportional representation of skeletal elements (elements with high marrow content, such as stylopodials and zeugopodials); (2) age at death of these animals (from infantile to advanced adult); (3) the position and function of cutmarks and toothmarks (mainly oblique and longitudinal incisions on limb bones diaphyses); (4) archaeostratigraphic distribution of their remains in the assemblage; and (5) presence of refits among the bones located at this archaeostratigraphical line. Evidence of anthropogenic processing of small prey (Oryctolagus cuniculus and Cygnus olor) is also identified at level XII. These discoveries imply the development of techniques different from those used to capture large and medium ungulates. From this perspective, a variety of strategies to obtain animal food can be documented at Bolomor Cave. This phenomenon can be related to the highly adaptive subsistence strategies of these hominids, who could take advantage of the benefits offered by a diverse and rich environment. In general, the aim of this study is to provide data about the subsistence strategies of human groups from Bolomor Cave and contribute to knowledge about the human groups’ way of life of in the late Middle Pleistocene.     

A karyological study of Allium rouyi Gautier (Liliaceae), a recently rediscovered endemic species from the south of Spain

A population of Allium rouyi, previously considered an extinct species, has recently been rediscovered. From this sample, the somatic chromosome number and detailed chromosome morphology is presented. Using the karyological data, relationships between A. rouyi and allied species are discussed.
