Castro FFCLRP-USP, Ribeirão Preto-SP 2008 3 Logotipo: A concepção tripartida do logotipo do VI Simpósio Brasileiro de Paleontologia de Vertebrados reflete as três eras do Fanerozóico e suas denominações populares: Paleozóico ou “Era dos Peixes” (representado pelo tubarão Tribodus limae, apesar deste ser do Mesozóico), Mesozóico ou “Era dos Répteis” (representado pelo dinossauro Staurikosaurus pricei) e Cenozóico ou “Era dos Mamíferos” (representado pelo tigre dentes-de-sabre Smilodon populator). Ainda, os três táxons escolhidos são representativos dos, talvez, três mais importantes, ou ao menos mais famosos, depósitos fossilíferos contendo vertebrados no Brasil: a Formação Santana, Cretáceo inferior do sul do Ceará (representada por T. limae); o Grupo Rosário do Sul, Triássico médio-superior da região central do Rio Grande do Sul (representado por S. pricei); e as grutas calcárias do centro-norte de Minas Gerais (representadas por S. populator).

Aproximadamente um terço dos trabalhos apresentados naquele congresso guardava relação com esta subdisciplina da Paleontologia, o que segue ocorrendo em eventos similares. Constatou-se, então, o potencial, em termos de massa crítica, para a realização de um “Simpósio Brasileiro de Paleontologia de Vertebrados”, e o primeiro destes encontros ocorreu já no ano seguinte, no Instituto de Geociências da Universidade Federal do Rio Grande do Sul. As outras quatro edições do evento tiveram lugar, respectivamente, no Museu Nacional, Rio de Janeiro (2000), na Universidade Estadual do Rio de Janeiro (2003); na UNESP de Rio Claro-SP (2004), e na Universidade Federal de Santa Maria-RS (2006). Desde então, o SBPV (como tem sido comumente denominado) estabeleceu-se como o principal evento desta natureza em nosso país. O que se iniciou como um encontro de pequenas dimensões, com organização baseada em infra-estrutura e custeio universitários, foi aos poucos apresentando maior participação, visibilidade e necessidades, requerendo maior investimento. Neste contexto, a Comissão Organizadora agradece o aporte financeiro das entidades que apoiaram o VI SBPV, a saber: Petrobrás, CNPq, CAPES e Sociedade Brasileira de Paleontologia. É com imenso prazer que o Laboratório de Paleontologia, FFCLRP-USP, sedia em Ribeirão Preto a sexta edição do Simpósio Brasileiro de Paleontologia de Vertebrados. O VI SBPV foi programado com uma estruturação na qual os três dias do evento contarão com trabalhos envolvendo temas-chave, que representam as três principais subáreas da Paleontologia de Vertebrados: Paleoictiologia, Paleoherpetologia e Paleomastozoologia. Adicionalmente, foi organizada uma sessão com trabalhos relacionados a ensino de Paleontologia e técnicas paleontológicas, além de uma exposição de paleoarte. Também foram programadas palestras e mesas-redondas acerca de temas paleontológicos atuais, controversos e de interesse geral. Esta é a segunda vez, em seis edições, que o Simpósio Brasileiro de Paleontologia de Vertebrados ocorre no Estado de São Paulo, podendo ser este um momento oportuno para avaliar a dinâmica das pesquisas com vertebrados fósseis que aqui se desenvolvem. Em verdade, face a iniciativas privadas, como a organização de exposições e instalação de museus em cidades do interior, o incentivo estadual nos parece claudicante. Paleontólogos de vertebrados nos quadros das instituições públicas de São Paulo são em número equivalente àqueles de cidades como Rio de Janeiro e Porto Alegre, o que seguramente não condiz com a relevância científico-tecnológica do estado. As posturas que resultaram em tal 7 cenário, talvez sejam as mesmo que levaram a FAPESP, com base em parecer de sua assessoria ad hoc, não estar relacionada entre as agencias que apoiaram a realização deste encontro. De resto, esperamos, com a organização do VI SBPV, contribuir no sentido de ao menos dar maior visibilidade à Paleontologia de Vertebrados Junto à comunidade científica de São Paulo. O presente boletim conta com 135 resumos ordenados alfabeticamente pelo sobrenome do primeiro autor. Estes foram todos analisados pelos editores, bem como por pelo menos um membro da Comissão Científica, aos quais os editores expressam seu reconhecimento. A maioria dos resumos foi reencaminhada para os autores, tendo sido aceitos depois de efetuadas as modificações sugeridas. No total, foram inscritos trabalhos de 211 autores e co-autores, de 12 estados brasileiros,

  • Sauropareion Anoplus, with a Discussion of Possible Life History
    The postcranial skeleton of the Early Triassic parareptile Sauropareion anoplus, with a discussion of possible life history MARK J. MACDOUGALL, SEAN P. MODESTO, and JENNIFER BOTHA−BRINK MacDougall, M.J., Modesto, S.P., and Botha−Brink, J. 2013. The postcranial skeleton of the Early Triassic parareptile Sauropareion anoplus, with a discussion of possible life history. Acta Palaeontologica Polonica 58 (4): 737–749. The skeletal anatomy of the Early Triassic (Induan) procolophonid reptile Sauropareion anoplus is described on the basis of three partial skeletons from Vangfontein, Middelburg District, South Africa. Together these three specimens preserve the large majority of the pectoral and pelvic girdles, articulated forelimbs and hindlimbs, and all but the caudal portion of the vertebral column, elements hitherto undescribed. Our phylogenetic analysis of the Procolophonoidea is consonant with previous work, positing S. anoplus as the sister taxon to a clade composed of all other procolophonids exclusive of Coletta seca. Previous studies have suggested that procolophonids were burrowers, and this seems to have been the case for S. anoplus, based on comparisons with characteristic skeletal anatomy of living digging animals, such as the presence of a spade−shaped skull, robust phalanges, and large unguals. Key words: Parareptilia, Procolophonidae, phylogenetic analysis, burrowing, Induan, Triassic, South Africa. Mark J.

  • Studies on Continental Late Triassic Tetrapod Biochronology. I. the Type Locality of Saturnalia Tupiniquim and the Faunal Succession in South Brazil
    Journal of South American Earth Sciences 19 (2005) 205–218 www.elsevier.com/locate/jsames Studies on continental Late Triassic tetrapod biochronology. I. The type locality of Saturnalia tupiniquim and the faunal succession in south Brazil Max Cardoso Langer* Departamento de Biologia, FFCLRP, Universidade de Sa˜o Paulo (USP), Av. Bandeirantes 3900, 14040-901 Ribeira˜o Preto, SP, Brazil Received 1 November 2003; accepted 1 January 2005 Abstract Late Triassic deposits of the Parana´ Basin, Rio Grande do Sul, Brazil, encompass a single third-order, tetrapod-bearing sedimentary sequence that includes parts of the Alemoa Member (Santa Maria Formation) and the Caturrita Formation. A rich, diverse succession of terrestrial tetrapod communities is recorded in these sediments, which can be divided into at least three faunal associations. The stem- sauropodomorph Saturnalia tupiniquim was collected in the locality known as ‘Waldsanga’ near the city of Santa Maria. In that area, the deposits of the Alemoa Member yield the ‘Alemoa local fauna,’ which typifies the first association; includes the rhynchosaur Hyperodapedon, aetosaurs, and basal dinosaurs; and is coeval with the lower fauna of the Ischigualasto Formation, Bermejo Basin, NW Argentina. The second association is recorded in deposits of both the Alemoa Member and the Caturrita Formation, characterized by the rhynchosaur ‘Scaphonyx’ sulcognathus and the cynodont Exaeretodon, and correlated with the upper fauna of the Ischigualasto Formation. Various isolated outcrops of the Caturrita Formation yield tetrapod fossils that correspond to post-Ischigualastian faunas but might not belong to a single faunal association. The record of the dicynodont Jachaleria suggests correlations with the lower part of the Los Colorados Formation, NW Argentina, whereas remains of derived tritheledontid cynodonts indicate younger ages.

Many titanosaurian dinosaurs are known only from fragmentary remains, making comparisons between taxa difficult because they often lack overlapping skeletal elements. This problem is particularly pronounced for the exceptionally large-bodied members of this sauropod clade. Dreadnoughtus schrani is a well-preserved giant titanosaurian from the Upper Cretaceous (Campanian–Maastrichtian) Cerro Fortaleza Formation of southern Patagonia, Argentina.
