ABSTRACT. From the 1930s, Brazil experienced a growing national centralisation and the construction of Brasilidade (Brazilianness). The military regime (1964–85) deepened centralisation and emphasised national identity, little space being left for regional identities. With the political opening and the redemocratisation of Brazil, starting at the end of the 1970s, the stress was on differences in a period in which Brazil had already achieved a high degree of integration. Identities were re‐created, among them that of Rio Grande do Sul, the southernmost state of Brazil, where a strong revival of gaúcho culture took place. The 1980s and 1990s were marked by a growing development of activities and disputes linked to the gaúcho tradition. In spite of the fact that Rio Grande do Sul is predominantly urban and industrialised, this process reached out to the state's rural past and the equestrian figure of the gaúcho.  相似文献

Pretto, F.A., Schultz, C.L., Langer, M.C. 4.02.2015. New dinosaur remains from the Late Triassic of southern Brazil (Candelária Sequence, Hyperodapedon Assemblage Zone). Alcheringa 39, xxx–xxx. ISSN 0311-5518

The oldest unequivocal dinosaurian records come from Upper Triassic strata, mostly from Argentina and Brazil. Recent fieldwork in the Brazilian deposits of Ischigualastian age (late Carnian–earliest Norian) have resulted in the collection of a new specimen (UFRGS-PV-1240-T) identified as dinosaurian by the presence of a concave emargination on the ventral surface of the femoral head and a well-developed deltopectoral crest on the humerus, which extends for ca 40% of its estimated proximodistal length. Although fragmentary, the material increases the dinosaurian record from the Late Triassic of Brazil, which is still modest when compared with coeval Argentine strata. Additionally, UFRGS-PV-1240-T augments the dinosaurian diversity at the ‘Sítio Janner’ site, which was until now restricted to the sauropodomorph Pampadromaeus barberenai. The new specimen is larger than most early dinosaurians (except for herrerasaurids), implying that members of the group were already occupying niches otherwise explored by other larger-bodied taxa in the ‘Sítio Janner’ palaeofauna, and Late Triassic palaeoenvironments in general.

Archaeological excavations of the PSG‐07 earthen mound at Pontal da Barra in Rio Grande do Sul, southern Brazil have revealed the earliest known evidence for the presence of domestic dog (Canis lupus familiaris ) in Brazil. This is the first reported pre‐Columbian example in the country. Analysis of morphology, morphometry, and dental enamel laminae identified a left maxillary molar 1, left maxillary molar 2 and attached fragments of the maxilla of C. l. familiaris . A direct radiocarbon date on a fragment of the maxilla provided an age range between 1701 and 1526 cal BP (2σ). This is within the range of other dates for the site, which indicate intermittent occupation between 2024 and 1027 cal BP (2σ). Data from carbon isotope analysis indicates a potential marine diet. However, nitrogen isotope analysis values are lower than expected for a marine diet. The sparse records of pre‐Columbian C. l. familiaris in the region emphasise the importance of the present work.

Monsanto’s request to commercialize its genetically-modified (GM) herbicide-resistant soybean technology in Brazil sparked heated debate and protest. This paper explores the conflict and illustrates how biosafety politics and policy outcomes are highly contested and situated, rather than controlled by external forces within the ever-expanding global economy. This paper argues that GM crops are not inherently artifacts of economic globalization and trade liberalization. What makes GM crops ‘global’ and part of a new iterative and uneven globalization process are the new and unanticipated sites of contradiction and contestation and the multi-scaled conflict over biotechnology governance. Political strategies taken by the state government in Rio Grande do Sul, Brazilian consumer protection activists, and Greenpeace exploit the new ‘nature’ of GM crops as a means to expand the debate, change the rules governing the genetic commons, and consequently, rescale biotechnology governance.  相似文献

Fieldwork involving survey, detailed topographic mapping, and excavations in Pinhal da Serra, Rio Grande do Sul, Brazil, has revealed a highly-structured landscape revolving around funerary/ceremonial structures that began around A.D. 1000. This paper focuses on the results of detailed topographic survey of mound and enclosure complexes and their interpretation in light of southern Jê ethnohistorical and ethnographic data. We compare the architectural patterns of mortuary architecture from this study with fundamental spatial features of historic Kaingang’s social organisation, mortuary rituals and cosmogony myth. Our results suggest historical continuity in the organisation of space in cardinal directions (E–W), topography (low and high places), and in circular/concentric spatiality revealed in the southern proto-Jê mound and enclosure complexes. It is argued that small paired mound and enclosure complexes are associated with the material representation of a dual ranked opposition materialised in proto-Jê moiety cemeteries where important persona were buried.  相似文献

Bittencourt, J.S., Leal, L.A., Langer, M.C. & Azevedo, S.A.K., June 2012. An additional basal sauropodomorph specimen from theUpperTriassic Caturrita Formation, southern Brazil, with comments on the biogeography of plateosaurids. Alcheringa, 1–10. ISSN0311-5518.

We describe an additional saurischian specimen from the Caturrita Formation (Norian) of the Parana Basin, southern Brazil. This material was collected in the 1950s and remained unstudied due to its fragmentary condition. Detailed comparisons with other saurischians worldwide reveal that some characters of the ilium, including the low ventral projection of the medial wall of the acetabulum and its concave ventral margin, together with the short triangular shape of the pre-acetabular process and its mound-like dorsocaudal edge, resemble those of sauropodomorphs such as Plateosaurus and Riojasaurus. This set of traits suggests that MN 1326-V has affinities with basal Sauropodomorpha, probably closer to plateosaurians than to Saturnalia-like taxa. Previous records of this clade in the Caturrita Formation include Unaysaurus, which has been related to Plateosaurus within Plateosauridae. Alternative schemes suggest that plateosaurids include Plateosaurus plus the Argentinean ‘prosauropods’ Coloradisaurus and Riojasaurus. Both hypotheses raise biogeographic questions, as a close relationship between faunas from South America and Europe excluding Africa and North America is not supported by geological and biostratigraphical evidence. Additionally, the absence of plateosaurids in other continents suggests that the geographical distribution of thistaxon is inconsistent with the geological history of western Pangaea, and this demands further investigations of the phylogeny of sauropodomorphs or improved sampling.

Góis, F., Scillato-Yané, G.J., Carlini, A.A. & Guilherme, E. 2013. A new species of Scirrotherium Edmund & Theodor, 1997 (Xenarthra, Cingulata, Pampatheriidae) from the late Miocene of South America. Alcheringa 37, 175–186. ISSN 0311-5518.

A new species of Scirrotherium Edmund & Theodor (Pampatheriidae) is described: S. carinatum. This genus was previously represented by a single species, S. hondaensis Edmund & Theodor, 1997, recorded from the middle Miocene (Laventan) of Colombia. Pampathere remains are common in the ‘Conglomerado osífero’ (late Miocene) of the Ituzaingó Formation in the Paraná River cliffs of Entre Ríos, Chubut (Argentina) and Acre (Brazil). All of them were referred to Kraglievichia paranense, and they are mostly osteoderms. However, only a few of these specimens are strictly consistent with that species. The new species described herein differs from S. hondaensis in having very thin osteoderms with more elaborate ornamentation. The movable band (or imbricate) osteoderms have a sculptured exposed surface and a single transverse row of anterior foramina; the lateral margins are wider and also bear foramina, and the longitudinal central elevation is long and proximally wide, and forms a posteriorly raised crest. This elevation is delimited by a fairly broad and shallow depression on each side, separating the marginal elevation from the longitudinal central one. The exposed surfaces of fixed (or fused) osteoderms bear large and deep anterior foramina, the longitudinal central elevation and delimiting depressions are very pronounced. This new species increases the known diversity of the pampatheres from the ‘Conglomerado osífero’. Additionally, a new nomenclatural scheme for Pampatheriidae osteoderms is proposed.

For years archaeologists in New Mexico, particularly in the northern Rio Grande region have noticed a very fine-grained what appeared to be mafic or basalt raw material source in late Paleoindian and Archaic contexts in northern New Mexico and southern Colorado. Indeed, a number of Folsom, Cody, Plainview, and Archaic bifaces are produced from this material. It appeared that there were at least two possible very fine-grained volcanics that could be the sources for these raw materials – San Antonio Mountain in far northern New Mexico, in the Taos Plateau Volcanic Field, and Cerros del Rio, on the east side of Bandelier National Monument right above the Rio Grande. After reconnaissance collections at the two probable sources, the short story is that the vast majority of “basalt” artifacts were indeed produced from one of these sources, but they are petrologically dacite and silicic volcanic rocks. An additional dacite source, called here the “Newman Dome”, also in the Taos Plateau Volcanic Field was discovered in the 1980s, but remained mainly discussed in the gray literature by CRM archaeologists. Examination of various Paleoindian and Archaic collections from the northern and middle Rio Grande indicates a strong preference for this silicic rock for the production of chipped stone tools, and in concert with obsidian source provenance studies has increased our ability to reconstruct procurement and range in these preceramic periods. These high-alkali dacite sources are easily discriminated with their trace element compositions, and based on this study, procurement seems to be dominantly restricted to these three sources in the region. Here I discuss the petrology, geochemistry, and some of the archaeological issues of these sources and their utility in the Southwest archaeological endeavor in an effort to bring these important prehistoric raw materials into the published realm.  相似文献

The Rio Grande do Norte astrolabe may have been found in Brazilian waters, although its provenance is unclear. It was bought and sold at auction in the Unites States in 2011, and the instrument represents a well-preserved specimen within a small and poorly understood collection of published marine astrolabes. It is signed by Agostinho de Goes Raposo, a member of a line of documented Portuguese astrolabe makers, and dated to 1656. This paper relates the condition, treatment, and ethical situation of the artifact, and hopes to advance our understanding of this class of navigation instruments.  相似文献

A new macropodine genus and species, Silvaroo bila, is described from the Pliocene Chinchilla Sand of Queensland. The generic concept of Protemnodon is reviewed, and it is concluded that two Pliocene species previously placed in that genus (bandharr and buloloensis) belong in Silvaroo. Species of Silvaroo resemble the modern forest wallabies of Papua New Guinea (species of Dorcopsis and Dorcopsulus) and also bear close phenetic resemblance to the late Miocene Dorcopsoides fossilis. Forest wallabies are not known from mainland Australia after the middle Pliocene, but occur in the late Pliocene and Pleistocene of New Guinea.  相似文献

ABSTRACT

The article focuses on temporary and improvised cultural spaces in marginalized neighbourhoods of Rio de Janeiro, Brazil. They are presented here as alternatives to current urban and cultural policies, often based on international ‘best practices’ models with exclusionary and segregating consequences. It begins with a brief overview into North American and Western European cultural planning policies. It then analyses the instability of cultural policies in Brazil, highlighting that, after a period of State recognition of bottom-up actions, administrators have turned to a contradictory planning scheme that mixes outdated and recent international trends, leading lower-income inhabitants to self-build their own cultural spaces. Unlike many products of today’s global strand of ‘tactic urbanism’, Rio’s temporary spaces are politically charged territories of resistance. An example is ‘Cine Taquara’ – an improvised cinema and debate forum that illustrates how, in an unequal city, such initiatives can do more towards social inclusion than ready-made models.  相似文献

Several bones from the Late Pleistocene archaeological site, Kutikina Cave, in southwest Tasmania, show pathological conditions. The majority of these specimens represent Bennett's or red‐necked wallaby (Macropus rufogriseus), with a single specimen of the Common wombat (Vombatus ursinus) recorded. While there has been extensive work in this region of Australia since the early 1980s, this is the first record of palaeopathology from the late Pleistocene of Tasmania, and the first from a human accumulation of predominately macropod material. The palaeopathology raises several questions concerning the mobility of these animals which might have increased their susceptibly to predation, while some of the effected elements are fragmented, suggesting that people utilised these bones despite their deformities.

Ubilla, M. & Rinderknecht, A., April 2016. Lagostomus maximus (Desmarest) (Rodentia, Chinchillidae), the extant plains vizcacha in the Late Pleistocene of Uruguay. Alcheringa 40, xxx–xxx. ISSN 0311-5518

The extant plains vizcacha, Lagostomus maximus, is described from the Late Pleistocene (Dolores Formation) of Uruguay based on an almost complete articulated skeleton. It is compared with the nominally extinct Pleistocene species of the genus. An AMS 14C taxon-age is determined for L. maximus at 11 879 ± 95 years BP (cal. BP 13 898–13 941). Lagostomus maximus is absent from modern mammal communities in Uruguay, and no Holocene evidence is available. Because L. maximus exhibits remarkable sexual and ontogenetic dimorphism, we examined a range of juvenile, sub-adult and adult male and female specimens. It is not possible to differentiate the articulated Pleistocene fossil from sub-adult specimens of L. maximus based on this sample. Moreover, the skull characteristics, including a broad vertical ramus of the zygomatic arch, semi-circular temporal crest and short robust sagittal crest, most closely resemble extant female individuals. Molar size is non-predictive for ontogenetic stage or body mass because it reaches stability during early adulthood. Other fragmentary skull remains are herein assigned to L. sp. cf. L. maximus. Lagostomus cavifrons from the Pleistocene of Argentina is considered synonymous with L. maximus. Its character states concur with the range of intraspecific variability and it has been established on a young adult or adult male individual. Likewise, the other Argentinean Pleistocene species based on incomplete mandibles, L. angustidens, L. striatus, L. heterogenidens, L. egenus, L. minimus and L. debilis, concur with ontogenetic morphs and are here assigned to Lagostomus sp. The ecological preferences of extant L. maximus infer open arid or semi-arid landscapes for the latest Pleistocene of southern Uruguay. This hypothesis is reinforced by the coeval presence of Microcavia, Galea and small camelids in the same strata. The Last Glacial Maximum likely promoted this environmental setting. Latest Pleistocene or early Holocene climatic change might have facilitated local extinctions and/or range shifts among this mammal fauna.

Sandro Marcelo Scheffler, Rodrigo Scalise, Horodyski & Elvio Pinto, Bosetti, 2018. Morphology, palaeoecology and taphonomy of the Devonian mitrate Placocystella langei from Paraná Basin, Brazil. Alcheringa 43, 228–240. ISSN 0311-5518.

The original holotype and paratypes of the stylophoran mitrate Placocystella langei (Echinodermata) are definitively lost. A neotype is designated here, based on new material collected in the marine Devonian strata of the Apucarana Sub-basin, Paraná, Brazil. Placocystella langei was the first species of Stylophora to be identified in Devonian basins from Brazil. Its range extends from the late Emsian to early Givetian. Taphonomic data indicate that P. langei specimens were preserved in a storm-influenced, transitional offshore environment, and that skeletal remains were few exposed at the water–sediment surface. Considering that the specimens do not exhibit evidence of reworking, it is possible that their final burial was rapid and definitive, which facilitated their almost complete preservation. Finally, taphonomic, diagenetic and sedimentologic data all suggest a shallow infaunal habit for Placocystella langei.

The first record of a permianellid species from the Leptodus shales of the Gua Musang Formation, northwest Pahang, Peninsular Malaysia is documented. The specimen is assigned to Permianella typica He & Zhu, 1979 and is most likely late Guadalupian in age based on its association with Vediproductus Sarytcheva (in Ruzhentsev & Sarytcheva 1965). This new record is the most southerly occurrence of the genus Permianella.  相似文献

Previous studies of the dentition and cranial base of Hadronomas puckridgi Woodburne suggested that this large, Late Miocene kangaroo might be related to the Sthenurinae. A recently recovered specimen, in which the neurocranium, rostrum and some of the incisors are preserved, reveals a more definite affinity with the sthenurines in its possession of laterally expanded postorbital crests of the frontals, reduced I2 accompanied by enlarged I3, the presence of a well-developed posterior mental foramen, a deep, posteriorly situated digastric eminence and elevated pterygoid fossa of the dentary.  相似文献

Place names have the potential to aid in the investigation of regional settlement histories because they reflect the importance of specific locations in the social or cultural memories of indigenous groups. Unique place names for ancient habitation sites such as villages or hamlets, i.e., those names for which there are no cognates in other languages, suggest that those ancient villages or hamlets still retain the names given to them by their original inhabitants. Here, we present Tewa place names for habitation sites identified archaeologically in the northern Rio Grande Valley of New Mexico. The results of our study strongly suggest that the Tewa language was spoken in the northern Rio Grande Valley, specifically, within the southern Tewa Basin, as early as the Late Developmental period (a.d. 900–1200), thus challenging the currently well-accepted model postulating a Mesa Verde origin for the Tewa language and culture.  相似文献

The water vole, genus Arvicola, is characterised by a broad geographic distribution throughout Europe and is widespread during the late Middle and Upper Pleistocene. This genus is used as a major biostratigraphic tool within the Quaternary. Specific determinations using the Schmelzband-Differenzierung-Quotient or SDQ have identified many chronospecies within the fossil species Arvicola cantiana (Hinton, 1910). As SDQ calculation remains limited, this study reappraises the Arvicola genus in terms of morphodiversity and morphospace using outline analysis which takes into account the tooth as a whole. Outline analysis suggests that one single species of Arvicola, A. cantiana, was present during the Pleistocene. This species shows great variability with no trends or patterns in morphospace. Thus, these results call into question the reliability of SDQ for specific determinations and throw doubt on the biochronological framework based on Arvicola.  相似文献

Cidade, G.M., Souza-Filho, J.P., Hsiou, A.S., Brochu, C.A., & Riff, D., 18 March 2019. New specimens of Mourasuchus (Alligatoroidea, Caimaninae) from the Miocene of Brazil and Bolivia and their taxonomic and anatomic implications. Alcheringa 43, 261–278. ISSN 0311-5518.

Mourasuchus is one of the most peculiar crocodylians of all time, showing an unusual ‘duck-faced’ rostrum with thin, gracile mandibles. It includes four species restricted to the South American Miocene. Here, we describe ten late Miocene specimens of Mourasuchus, nine from the Solimões Formation of Brazil and one from Bolivia. All specimens are assigned to M. arendsi, but this assignment may change as the diversity and relationships within Mourasuchus are better understood. We also discuss several issues pertinent to the morphology of Mourasuchus: the presence of a braincase neomorph (the laterocaudal bridge), hypotheses about sexual dimorphism, the function of the squamosal ‘horns’ the presence of possible thermoregulatory functions in the genus. Additionally, the paleogeographic distribution of Mourasuchus in the Miocene of South America is also discussed.
