[email protected] ABSTRACT – The South American Teiidae fossil record is restricted to the Cenozoic, and the most conspicuous remains were found in Early to Late Miocene of Argentina and Middle Miocene of Colombia and Peru, all represented by Tupinambinae lizards. Here, we describe a right fragmentary dentary and one dorsal vertebra collected in the Solimões Formation at the Talismã locality, situated on the Purus River, in the southwestern Brazilian Amazonia (Late Miocene). The material is tentatively conferred to the extinct genus Paradracaena. It represents the first record of lizards for the Neogene southwestern Brazilian Amazonia. Key words: Teiidae, Tupinambinae, Solimões Formation, Miocene, southwestern Brazilian Amazonia. RESUMO – O registro fóssil de Teiidae para a América do Sul é restrito ao Cenozóico. Os fósseis mais significantes são encontrados a partir do Mioceno inferior ao superior da Argentina e Mioceno médio da Colômbia e Peru, principalmente representados pelos Tupinambinae. Neste trabalho descreve-se um fragmento de dentário direito e uma vértebra dorsal coletados em sedimentos da Formação Solimões, na localidade Talismã, alto rio Purus, sudoeste da Amazônia brasileira. -

Lower Miocene Alligatoroids (Crocodylia) from the Castillo Formation, Northwest of Venezuela
Palaeobiodiversity and Palaeoenvironments https://doi.org/10.1007/s12549-018-0332-5 ORIGINAL PAPER Lower Miocene alligatoroids (Crocodylia) from the Castillo Formation, northwest of Venezuela Andrés Solórzano1,2 & Ascanio D. Rincón1 & Giovanne M. Cidade3 & Mónica Núñez-Flores1,4 & Leonardo Sánchez1 Received: 23 June 2017 /Revised: 27 December 2017 /Accepted: 14 May 2018 # Senckenberg Gesellschaft für Naturforschung and Springer-Verlag GmbH Germany, part of Springer Nature 2018 Abstract Crocodyliform diversity was particularly high during the middle and late Miocene of South America, with up to 12 species recovered from a single geological unit. Nonetheless, the early Miocene fossil record of low-latitude vertebrates is scarce; hence, crocodylians remain poorly known in the region. The Castillo Formation, located in the northwest of Venezuela, preserves an interesting vertebrate fauna with a well-constrained late early Miocene age. Previous work dealing with crocodylians of this formation only recorded three taxa: the gavialoid Siquisiquesuchus venezuelensis and Gryposuchus sp. and indeterminate alligatoroid remains. New cranial and mandibular material recently recovered from the Castillo Formation allows us to document four previously unrecognised alligatoroid forms: Purussaurus sp., Caiman sp., an indeterminate caimanine and an indeterminate alligatoroid. With six taxa, the crocodylian assemblage reveals a previously undocumented relatively high taxonomic diversity in the early Miocene. The Castillo crocodylians show a broad range of morphological disparity and body sizes ranging from small (2.5 m–62 kg) to large (7.5 m–1600 kg) taxa. Thus, crocodylian niche partition, as well as the abundance and variety of resources and environmental heterogeneity of aquatic ecosystems in South America, were already established by at least the early Miocene. -
A Fundamental Precambrian–Phanerozoic Shift in Earth's Glacial
Tectonophysics 375 (2003) 353–385 www.elsevier.com/locate/tecto A fundamental Precambrian–Phanerozoic shift in earth’s glacial style? D.A.D. Evans* Department of Geology and Geophysics, Yale University, P.O. Box 208109, 210 Whitney Avenue, New Haven, CT 06520-8109, USA Received 24 May 2002; received in revised form 25 March 2003; accepted 5 June 2003 Abstract It has recently been found that Neoproterozoic glaciogenic sediments were deposited mainly at low paleolatitudes, in marked qualitative contrast to their Pleistocene counterparts. Several competing models vie for explanation of this unusual paleoclimatic record, most notably the high-obliquity hypothesis and varying degrees of the snowball Earth scenario. The present study quantitatively compiles the global distributions of Miocene–Pleistocene glaciogenic deposits and paleomagnetically derived paleolatitudes for Late Devonian–Permian, Ordovician–Silurian, Neoproterozoic, and Paleoproterozoic glaciogenic rocks. Whereas high depositional latitudes dominate all Phanerozoic ice ages, exclusively low paleolatitudes characterize both of the major Precambrian glacial epochs. Transition between these modes occurred within a 100-My interval, precisely coeval with the Neoproterozoic–Cambrian ‘‘explosion’’ of metazoan diversity. Glaciation is much more common since 750 Ma than in the preceding sedimentary record, an observation that cannot be ascribed merely to preservation. These patterns suggest an overall cooling of Earth’s longterm climate, superimposed by developing regulatory feedbacks -

Matieland 7602, South Africa ABSTRACT The Lu-Hf isotopic composition of detrital zircons has been used to investigate the crustal evolution of the northern part of the West African (raton (WAC). The zircons were separated from six samples of siliciclastic sedimentary rocks from the main Neoproterozic stratigraphic units of the Anti-Atlas belt, from the SiIWa and Zenaga inliers. The data suggest that the north part of the WAC formed during three cycles of juvenile crust formation with variable amount of reworking of older crust. The younger group of zircons, with a main population clustering around 610 Ma, has a predominant juvenile character and Keyworili: evidences of moderate mixing with Paleoproterozoic and Neoarchean crust, which supports that most Anti-Atlas belt igneous and metamorphic rocks where zircons originally crystallized were formed in an ensialic mag Morocco Hfisotopes matic arc environment. The group of zircons in the age range 1.79-2.3 Ca corresponds to the major crust Detrital zircon forming event in the WAC: the Eburnian orogeny. -
Sa˜O Luıs Craton and Gurupi Belt (Brazil)
Sa˜o Luı´s Craton and Gurupi Belt (Brazil): possible links with the West African Craton and surrounding Pan-African belts E. L. KLEIN1,2 & C. A. V. MOURA3 1CPRM (Companhia de Pesquisa de Recursos Minerais)/Geological Survey of Brazil, Av. Dr. Freitas, 3645, Bele´m-PA, CEP 66095-110, Brazil (e-mail: [email protected]) 2Researcher at CNPq (Conselho Nacional de Desenvolvimento Cientı´fico e Tecnolo´gico) 3Laborato´rio de Geologia Isoto´pica/Para´-Iso, Universidade Federal do Para´, Centro de Geocieˆncias, CP 1611, Bele´m-PA, Brazil, CEP 66075-900 Abstract: The Sa˜o Luı´s Craton and the Palaeoproterozoic basement rocks of the Neoproterozoic Gurupi Belt in northern Brazil are part of an orogen having an early accretionary phase at 2240– 2150 Ma and a late collisional phase at 2080 + 20 Ma. Geological, geochronological and isotopic evidence, along with palaeogeographic reconstructions, strongly suggest that these Brazilian terrains were contiguous with the West African Craton in Palaeoproterozoic times, and that this landmass apparently survived subsequent continental break-up until its incorporation in Rodinia. The Gurupi Belt is an orogen developed in the southern margin of the West African–Sa˜o Luı´s Craton at c. 750–550 Ma, after the break up of Rodinia. Factors such as present-day and possible past geographical positions, the timing of a few well-characterized events, the structural polarity and internal structure of the belt, in addition to other indirect evidence, all favour correlation between the Gurupi Belt and other Brasiliano/Pan-African belts, especially the Me´dio Coreau´ domain of the Borborema Province and the Trans-Saharan Belt of Africa, despite the lack of proven physical links between them. -
