L'Azilien ancien de Cueva Oscura de Ania (Las Regueras, Asturias, Espagne)

Recent definition of the Cantabrian Lower Azilian has turned the Late Upper Magdalenian/Azilian transition into one of the most interesting archaeological ages in the area. This period is considered representing the earliest Azilian groups in Asturias. Critic review of Cueva Oscura de Ania record, in the center of Asturias, has allowed us to give full details of the Lower Azilian archaeological characteristics. Cueva Oscura de Ania archaeological collection shows archaic traits, close to those from Cueva de Los Azules and Cueva de La Riera, two eastern asturian sites. These likenesses suggest a high stylistic and technical uniformity in distant areas during a critical period, when Palaeolithic groups changed their subsistence strategies. Cueva Oscura de Ania archaeological and polinic records suggest that this deposit was built at the beginning of the paleoclimatic phase known as Alleröd/Cantabrian VIII (12 000-10?800 BP), when numerous cantabrian sites suffered high erosion processes. All these circumstances convert Cueva Oscura de Ania in a fundamental site to get a best knowledge of the origin and development of the Cantabrian Azilian. The study of its bone collection allows us outline new hypothesis about this archaeological period.     

Bacteria isolated from the rocks supporting prehistoricpaintings in two shelters from Sierra de Cazorla,Jaen, Spain

The Sierra de Cazorla, Jaen, Spain, is characterizedby the presence of a number of shelters or smallcavities with important late prehistoric paintings,the so-called schematic rock art painting. Themicrobial population of the rocks supporting paintingsfrom two shelters was investigated. Bacteria isolatedfrom Cueva del Encajero triplicated the number ofthose isolated from Cueva de la Graja, as correspondedto a higher environmental humidity. However, thebacteria isolated from Cueva de la Graja weremetabolically more active and able to use a highernumber of carbon sources than those of Cueva delEncajero. As demonstrated by cluster analysis themicrobial communities from both shelters are related,in spite of the different ecological conditions andgeographical distribution.     

The value of endangered species in protected areas at risk: the case of the leatherback turtle in the Dominican Republic

Protected areas are considered essential elements for global biodiversity conservation. They may not necessarily result in an effective conservation of resources in developing countries due to lack of funding for management and enforcement. In addition, poor governance aligned with conflicts of economic interests related to their use can further threaten their integrity and persistence. In the Dominican Republic, the western beaches of the Jaragua National Park (JNP), a protected area which is also part of a UNESCO Biosphere Reserve, have been proposed for development using a mass-tourism model. One of the most charismatic species found in this area is the leatherback turtle (Dermochelys coriacea). In the present study, we assess hatching success, and factors affecting it, to determine the reproductive value across the area for the leatherback turtle. The main factors found driving hatching success at the study beaches are beach sector, incubation duration, date of lay and clutch size. Our results show that clutches in La Cueva (located in the buffer zone of the park) and Bahía de las Águilas (located inside the limits of the park) have an unusually high hatching success (~75 %) for this species, highlighting the importance of increasing protection efforts at these sites. We strongly recommend including La Cueva inside the limits of the JNP.     

The Iberian record of the puma-like cat Puma pardoides (Owen, 1846) (Carnivora,Felidae)

Fossil puma-like cats (Puma pardoides) are recorded from several Late Pliocene to Early Pleistocene Eurasian localities, but the interpretation of the phylogenetic relationships between them and the extant puma (Puma concolor) remains controversial. In the past, extinct puma-like cats have been classified into several genera and species, and a close relationship with both pumas (Puma concolor) and snow leopards (Uncia uncia) has been suggested. Here, we describe the fossil remains of puma-like cats from the Iberian Peninsula. These remains (from the localities of La Puebla de Valverde, Cueva Victoria and Vallparadís) cover the whole known chronological distribution of this species in Eurasia. Although there are dentognathic similarities with U. uncia, the Iberian remains of P. pardoides most closely resemble the extant P. concolor. It is concluded that P. pardoides is closely related to living pumas, which supports a likely Eurasian origin of the puma lineage.     

Lower Ordovician microfacies and microfossils from Cerro San Pedro (San Pedro de la Cueva,Sonora, Mexico), as a westernmost outcrop of the newly defined <Emphasis Type="Italic">Nuia</Emphasis> Province

The lowermost carbonate beds of the Cerro San Pedro (San Pedro de la Cueva, Sonora State, Mexico) previously assigned to the Mississippian, belong in fact to the lower Ordovician. The limestone of this succession is often dolomitized and chertified, and displays gastropods, pelmatozoans, sponges, and trilobites as major bioclastic components. The different microfacies show that high-energy grainstones, proximal tempestites, and distal tempestites dominated the sedimentation. The paleoenvironments of deposition correspond to an inner ramp, a mid-ramp, and perhaps the upper part of an outer ramp. The strata are characterized by the incertae sedis cyanobacteria Nuia sibirica. A taxonomic revision and discussion of these cyanobacteria, often confused with ooidic grains, is emphasized. Some data are presented on other microfossils, such as primitive, monothalamous foraminifers: Rauserina sp., Vicinesphaera sp., and Neoarchaesphaera sp., leperditicopida and their endolithic microperforations, and primitive chaetetids. Compared to the contemporaneous deposits of the USA, some paleobiological components, e.g., the lithistid siliceous sponges Archaeoscyphia, stromatoporoids? Pulchrilamina, and receptaculacean algae Calathium, are quite rare in the studied section of Sonora, but the predominance of tempestites in the carbonate succession shows that boundstones formed before were systematically eroded and resedimented. The paleogeographic implications are the following: (1) a lower Ordovician intertropical Nuia Province is newly defined in the western part of the lower Ordovician intertropical belt; (2) San Pedro de la Cueva constitutes one of the westernmost outcrops of this new Nuia Province; (3) from Sonora, Nuia extends eastward as far as South China; (4) due to its westernmost paleoposition, San Pedro de la Cueva was frequently affected by tropical storms; and (5) northern lower Ordovician terranes of Mexico (Sonora, Chihuahua, and Baja California) are entirely distinct from the southern ones (Oaxaca). The paleopositions and paleogeographic connections of these northern Mexican terranes with Laurentia, Avalonia, and peri-Gondwanan parts of South America, through the Iapetus and Rheic oceans, still remain disputable or unknown.     

Assessing the Archaeoparasitological Potential of Quids As a Source Material for Immunodiagnostic Analyses

In the present study, quids from La Cueva de los Muertos Chiquitos (CMC) were subjected to ELISA tests for 2 protozoan parasites, Toxoplasma gondii (n=45) and Trypanosoma cruzi (n=43). The people who occupied CMC, the Loma San Gabriel, lived throughout much of present-day Durango and Zacatecas in Mexico. The known pathoecology of these people puts them into at-risk categories for the transmission of T. gondii and T. cruzi. Human antibodies created in response to these 2 parasites can be detected in modern saliva using ELISA kits intended for use with human serum. For these reasons, quids were reconstituted and subjected to ELISA testing. All test wells yielded negative results. These results could be a factor of improper methods because there is no precedence for this work in the existing literature. The results could equally be a simple matter of parasite absence among those people who occupied CMC. A final consideration is the taphonomy of human antibodies and whether or not ELISA is a sufficient method for recovering antibodies from archaeological contexts. An additional ELISA test targeting secretory IgA (sIgA) was conducted to further examine the failure to detect parasite-induced antibodies from quids. Herein, the methods used for quid preparation and ELISA procedures are described so that they can be further developed by future researchers. The results are discussed in light of the potential future of quid analysis.     

Chewing lice of Procellaria aequinoctialis Linnaeus, 1758 in Brazil with a new host record

The white-chinned petrel (Procellaria aequinoctialis) is a seabird widely distributed in the circumpolar sub-Antarctic islands and subtropical regions, including Brazilian waters. Among the parasites present on the white-chinned petrel are the chewing lice. This seabird is parasitized by 4 known lice species to date. In this study we evaluated the ectoparasites of 2 white-chinned petrels rescued by an animal rehabilitation center in Rio de Janeiro, Brazil and recorded 4 species of chewing lice, of which 3 are already known for this host. One of the species however, has never been recorded in Brazil and another one has never been recorded parasitizing P. aequinoctialis, making this a new host record.     

The decapod community from the Early Pliocene (Zanclean) of “La Serra” quarry (San Miniato,Pisa, Toscana,central Italy): sedimentology,systematics, and palaeoenvironmental implications

We report an unusual and rich decapod crustacean assemblage from the early Pliocene (Zanclean), recently collected during the excavations of the “La Serra” quarry, located in La Serra, near San Miniato, Pisa (Toscana, central Italy). The studied specimens have been assigned, as follows: Axius sp., Callianassa chalmasii Brocchi, 1883, and Calliaxina cf. C. punica ( de Saint Laurent and Manning, 1982) (infraorder Axiidea de Saint Laurent, 1979); Gebiacantha tuscia Garassino, Pasini, De Angeli and Charbonnier sp. nov. (infraorder Gebiidea de Saint Laurent, 1979); Pagurus alatus Fabricius, 1775, and Pagurus sp. (infraorder Anomura MacLeay, 1838); Dromia neogenica Müller, 1978, Dromia sp., Medorippe cf. M. ampla Garassino, De Angeli, Gallo and Pasini, 2004, Ilia nucleus ( Linnaeus, 1758), Ristoria pliocaenica (Ristori, 1891), Pisa armata ( Latreille, 1803), Macropodia sp., Maja squinado (Herbst, 1788), Derilambrus angulifrons ( Latreille, 1825), Atelecyclus undecimdentatus (Herbst, 1783), Liocarcinus sp., Thalamita italica Garassino, Pasini, De Angeli and Charbonnier sp. nov., Pilumnus cf. P. hirtellus (Linnaeus, 1761), Eriphia cocchii Ristori, 1886, Goneplax rhomboides ( Linnaeus, 1758), Goneplax sacci Crema, 1895, (infraorder Brachyura Linnaeus, 1758). Moreover, two specimens have been assigned to callianassideans sensu lato and 13 specimens to indeterminate axiideans. Calliaxina Ngoc-Ho, 2003, Gebiacantha Ngoc-Ho, 1989, Ristoria Garassino, Pasini, De Angeli and Charbonnier gen. nov., and Macropodia Leach, 1814, are reported for the first time in the fossil record and the extant Pagurus alatus, Ilia nucleus, Pisa armata, Derilambrus angulifrons, and Pilumnus cf. P. hirtellus, are reported in the fossil record from the Pliocene. Everywhere “La Serra” quarry bio-community is very important, representing one of the richest and most diversified crustacean faunas from the Pliocene reported to date in the Mediterranean basin and worldwide, increasing notably the knowledge on the decapod populations and distribution during the early Pliocene. This community is indicative of a palaeoenvironment of shallow sublittoral water, with sandy-muddy and alternate hard shell bottom, partially covered or in proximity of seagrass, similar to the extant Mediterranean Posidonia beds, mainly inhabited by fossorial and benthonic decapods.     

Echinococcus vogeli Rausch and Bernstein, 1972, from the paca, Cuniculus paca L. (Rodentia: Dasyproctidae), in the Departamento de Santa Cruz, Bolivia

Among approximately 2,000 mammals examined for helminths in various regions of Bolivia during 1983-1987, cysts of Echinococcus vogeli Rausch and Bernstein, 1972, were found in a single paca, Cuniculus paca L., collected at La Laguna, Departamento de Santa Cruz (lat. 16 degrees 36'W; long. 62 degrees 42'S). This record, the first from Bolivia, represents a considerable extension of the known geographic range of this species in South America. Upon analysis of the morphologic characteristics of the protoscoleces derived from the cysts, the sizes of rostellar hooks from the material from the paca were found to be well within the ranges reported in previous studies. Statistical analysis of frequency distributions of hook characteristics revealed some deviations from normality. These results indicate that parametric statistics should be applied with caution in analyses of inter-and intraspecific variation of morphologic characteristics of hooks of metacestodes of the genus Echinococcus.     

The asian decapodHemigrapsus penicillatus (de Haan, 1835) (Grapsidae, Decapoda) introduced in European waters: status quo and future perspective

The Asian decapodHemigrapsus penicillatus (de Haan, 1835) was first recorded in European waters in 1994. The first specimens were collected in the estuary of Charente Maritime on the west coast of France close to La Rochelle. The current range in Europe covers Spanish shallow water habitats of the Bay of Biscay to areas north of La Rochelle (France). Densities of up to 20 specimens per square metre occur. This species has a high temperature and salinity tolerace and will expand its distribution in European waters. It is not clear whether this crab was introduced by shipping in ballast water or as a fouling organism. Based on a study of ship hull fouling in German dry docks this account provides evidence that hull fouling is a likely vector for the introduction of this crab. In August 1993, six juvenile specimens ofH. penicillatus were removed from the hull of a car-carrier. After its journey from Japan into European waters this vessel docked in the port of Bremerhaven (Germany) for a routine inspection and coating with antifouling paint.

Reconstitution 3D par Computerized-tomography (CT) et endocrâne virtuel du crâne 5 du site de la Sima de Los Huesos (Atapuerca)

The 3d Ct reconstruction and virtual brain endocast of Cranium 5 from the site of “La Sima de los Huesos” (Atapuerca), allows us to get new information to increase the study and knowledge of Homo heidelbergensis population, and to compare this specimen with others in the fossil record, in order to understand the evolutionary process of the brain, focusing on the middle Pleistocene period. Furthermore, we can observe the changes this species (Homo heidelbergensis) has undergone, at least in Sima de los Huesos population making comparative studies with African and Asian middle Pleistocene specimens. We have used the new data to compare European Homo heidelbergensis represented by SH5 with Kabwe, a controversial specimen considered by some authors like the African Homo heidelbergensis representative, in order to establish the similarities and differences between both specimens.     

A new Pliocene mollusk fauna from Mejillones, northern Chile

A new Pliocene (3.4 Ma) mollusk fauna from Mejillones Peninsula, northern Chile is described and compared with the Pliocene La Cueva fauna of little constrained age from central Chile and some species from the Huenteguapi Sandstone overlying the Ranquil Formation on Arauco Peninsula, south central Chile. Preliminary correlation is based on faunal similarities. A total of 45 taxa were identified, of which Cyclocardia kieli sp. nov. is new to science. New combinations are Macron escalonia (Vermeij and DeVries, 1997), Austrofusus steinmanni (Möricke, 1896) and Leukoma antiqua (King, 1832). For several species, the oldest occurrences and range extensions are reported. Co-occurrence of warm water taxa, previously assigned to MIS 11, and typical Pliocene taxa on Mejillones cannot be confirmed. Pliocene and Pleistocene mollusk faunas from Mejillones are listed for comparison.     

A new species of glypheid lobster,Glyphea pisuergae (Crustacea,Glypheoidea), from the Early Jurassic of Palencia,Basque-Cantabrian Basin,Spain

A new glypheid lobster (Crustacea, Glypheidae), Glyphea pisuergae sp. nov. is described from the Early Jurassic (late Pliensbachian–early Toarcian) of Salinas de Pisuerga, Palencia, Spain. This species represents the second record for the genus in the Early Jurassic.     

Apocricetus barrierei (Rodentia,Mammalia) from La Bullana 2B and La Bullana 3 (Cabriel Basin,Valencia, Spain). Revision of the Late Miocene–Early Pliocene forms of the genus Apocricetus

Apocricetus Freudenthal et al. (Treballs del Museu de Geologia de Barcelona 7: 11–93, 1998) is a medium to large Cricetinae, practically without mesolophids in the m1 and m2, with long third molars; anterior and posterior protolophule are present and the posterior metalophule is reduced or absent. Apocricetus barrierei (Mein and Michaux Comptes Rendus Academie de Sciences de Paris D 270: 2780–2783, 1970) was defined on the basis of three specimens from the French locality Chabrier. Apart from this site, several French and Spanish localities of Early Pliocene age contain remains of this species. Despite this extra material, the species is poorly characterized, and none of the localities contains material of all six dental elements. In this paper, two new assemblages from La Bullana 2B and La Bullana 3 (Cabriel Basin, Spain) are described. The rich assemblage from La Bullana 2B provides a better insight in the metrical and morphological variability of this species.     

Fossil Nelumbonaceae from the La Colonia Formation (Campanian–Maastrichtian,Upper Cretaceous), Chubut,Patagonia, Argentina

We describe here fossil leaves and fruits assignable to the family Nelumbonaceae Dumortier 1828. Fossils were collected at the Cañadón del Irupé locality, La Colonia Formation (Campanian–Maastrichtian, Upper Cretaceous), Chubut Province, Patagonia, Argentina. The fossil leaves are simple, with symmetrical and peltate lamina, orbicular in shape, and an entire margin. The venation is truly actinodromous with at least 15 primary veins, the secondary veins are poorly developed and intercalated with the primary veins, the third category vein is opposite, and the areoles are well-developed and 4- to 5-sided. These features are characteristic of the extant genus Nelumbo Adamson 1763, and the presence of these characters in the fossils allows their placement within this genus. Reproductive structures, similar to the fruit-receptacle of Nelumbo with fruits in situ, were found associated but not in organic connection with the leaves. These fossils constitute the only and oldest record for the family in the Southern Hemisphere. This record indicates that Nelumbo was more widespread in the past than today.     

Description of the male of Potamocypris villosa (Jurine, 1820) (Crustacea,Ostracoda)

A bisexual population of Potamocypris villosa, found in Lago de Encina, a mesotrophic lake in the Cantabrian mountains, NW Spain, is the first certain record of the male of this species. Valves and soft parts are described. Males of Potamocypris-species lack a furca although a rudimentary furca is always present in females. The same applies to species of related genera, such as Tanganyikacypridopsis and Plesiocypridopsis. Some remarks on the position of the genus Potamocypris in the Cyprinopsinae are presented.     

Reproductive activity and condition index of Holacanthus passer (Teleostei: Pomacanthidae) in the Gulf of California,Mexico

Annual variation and relationship between the gonadosomatic index (IG) and the condition index (K) of Holacanthus passer were evaluated in 194 specimens from Cueva de León, Gulf of California (24 degrees 02' N, 110 degrees 24' W). There was a significant negative correlation between IG and K in both sexes: indices exhibit an opposite seasonal pattern. The reproductive activity of both sexes is inversely related with nutritional status. There was a significant difference in IG but not in K values between males and females. The condition index may be used to determine reproduction time of the species in other localities without sacrificing the organisms. This could be a valuable tool to develop monitoring programs for fisheries and culture of this species.     

Early Neolithic agriculture in Ambrona, Provincia Soria, central Spain

The early Neolithic sites of La Lámpara and La Revilla del Campo in the Meseta Norte (Northern Meseta) plateau in central Spain produced evidence for early agriculture from the last third of the 6th millennium B.C. The hulled wheats Triticum monococcum (einkorn) and T. dicoccum (emmer) were identified from carbonised plant remains as well as from imprints in pottery and daub. Single finds of charred remains of Hordeum vulgare (barley), Papaver somniferum/setigerum (poppy) and Linum usitatissimum (linseed) indicated other cultivated crops. The wild plants mainly indicated arable weeds, partly from less fertile soils, and garrigue vegetation from poor pastures. The spectrum of crops from the Ambrona sites was compared to other inner Iberian sites as well as to Mediterranean sites. Sediment samples as well as mineral crusts from graves were analysed from the Neolithic tumulus of La Peña de la Abuela. Its diachronic collective burials had originated from a period of time during the first third of the 4th millennium B.C. Probably no crops, but many green vegetative parts of pine, oak, and juniper had been used as funeral gifts. Oak cupula development indicated early summer activities in the grave-mound. Wickerwork made of willow was used for embedding the dead bodies.     

Middle Palaeolithic burial is not a dead issue: the view from Qafzeh, Saint-Césaire, Kebara, Amud, and Dederiyeh.

Inferences of purposeful Middle Palaeolithic (MP) burial are almost universally accepted, despite published arguments that the pre-1960s discoveries are equally well explained by natural processes. In the modern human origins debate (perhaps the most hotly disputed question in palaeoanthropology) inferences of MP burial are crucial in arguments for an early Upper Pleistocene emergence of modern humans. The present paper contributed to that debate by re-examining a number of post-1960s excavations of MP hominid remains. Because these were excavated with meticulous attention to depositional circumstances and stratigraphic context, most palaeoanthropologists consider these inferences of purposeful burial to be based on irrefutable evidence. This paper focuses on the reasoning behind such claims, especially the assumption that articulated sketetal material is prima facie evidence for deliberate burial. First it reviews a range of processes operating in caves and rockshelters that condition the probability of articulated skeletal material preserving without hominid intervention. Processes such as deposition, decomposition, and disturbance are inherently more variable in caves and rockshelters than is usually acknowledged. The first section concludes that purposeful protection is not necessary to account for the preservation of articulated skeletal remains. The second part of the paper examines the published record from Qafzeh, Saint-Césaire, Kebara, Amud and Dederiyeh, where the majority of the remains claimed to have been buried are fragmented, incomplete, and disarticulated. This re-examination suggests that in all of the post-1960s cases of putative burial, the hominid remains occur in special depositional circumstances, which by themselves are sufficient to account for the preservation in evidence at these sites. This conclusion severely weakens arguments for purposeful burial at the five sites. Moreover, the equivocal nature of the evidence in the more recent cases renders even less secure the similar claims made for discoveries of hominid skeletal remains at La Chapelle-aux-Saints, Le Mousterier, La Ferrassie, Teshik-Tash, La Grotte du Régourdou, Shanidar, and several others. Finally, by highlighting the equivocal nature of the evidence, this paper underscores the ongoing need for palaeoanthropologists to specify as wide a range of taphonomic processes as possible when interpreting the archaeological record. This will aid in producing robust inferences, and will bring about increasingly accurate knowledge of when hominids became human.
