First report of swimming trace fossils of fish from the Upper Permian and Lower Triassic of the Dolomites (Italy). Annales Societatis Geologorum Poloniae, 88: xxx-xxx Abstract: In the Upper Permian continental to marginal-marine succession of the Southern Alps (Dolomites, north Italy), the ichnological record consists of diverse vertebrate footprints and non-diverse invertebrate trace fossils, mainly occurring in the “Bletterbach ichnoassociation” of the Val Gardena Sandstone Formation. After the Perm- ian-Triassic Boundary event, vertebrate ichnoassociations are scarce until the Middle Triassic (Anisian), whereas the uppermost Permian–Lower Triassic Werfen Formation preserves a rich invertebrate trace-fossil record. To date, fish body and trace fossils (Undichna) are very rare in the pre- and post-extinction deposits of the Dolomites; only Undichna gosiutensis Gibert, 2001 was identified in the “Voltago Conglomerate” (Middle Anisian), whereas some unidentified fossil fish casts were found in the Permian Val Gardena Sandstone and some fish remains in the overlying Werfen Formation.

Based on the different tectonic backgrounds of the middle Permian in northwest Sichuan Basin, the thrust nappe belt, the hidden front belt, and the depression belt are taken as the research units to comb and compare the geologic conditions of the middle Permian reservoir. The evaluation of source rocks and the comparison of hydrocarbon sources suggest that the middle Permian hydrocarbon mainly comes from the bottom of the lower Cambrian and middle Permian, and the foreland orogeny promoted the thermal evolution of Paleozoic source rocks in northwest Sichuan to high maturity and over maturity stage.

[email protected] ISMAR DE SOUZA CARVALHO Departamento de Geologia, Instituto de Geociências, UFRJ, 21949-900, Cidade Universitária, Rio de Janeiro, RJ, Brazil. [email protected] ABSTRACT – The Bauru Group is a sequence at least 300 m in thickness, of Cretaceous age (Turonian- Maastrichtian), located in southeastern Brazil (Bauru Basin), and consists of three formations, namely Adamantina, Uberaba and Marília. Throughout the Upper Cretaceous, there was an alternation between severely hot dry and rainy seasons, and a diverse fauna and flora was established in the basin. The ichnofossils studied were found in the Adamantina Formation outcrops and were identified as Arenicolites isp., ?Macanopsis isp., Palaeophycus heberti and Taenidium barretti, which reveal the burrowing behavior of the endobenthic invertebrates. There are also other biogenic structures such as plant root traces, coprolites and vertebrate fossil egg nests. The Adamantina Formation (Turonian-Santonian) is a sequence of fine sandstones, mudstones, siltstones and muddy sandstones, whose sediments are interpreted as deposited in exposed channel-bars and floodplains associated areas of braided fluvial environments. Key words: Bauru Basin, ichnofossils, late Cretaceous, continental palaeoenvironments, Adamantina Formation. RESUMO – O Grupo Bauru é uma seqüência de pelo menos 300 m de espessura, de idade cretácica (Turoniano- Maastrichtiano), localizada no Sudeste do Brasil (bacia Bauru), e consiste das formações Adamantina, Uberaba e Marília.

Palaeontology in the virtual era BOOK OF ABSTRACTS 6 4 PRESENTATION The 1st Palaeontological Virtual Congress (1st PVC) is just the natural consequence of the evolution of our surrounding world, with the emergence of new technologies that allow a wide range of communication possibilities. Within this context, the 1st PVC represents the frst attempt in palaeontology to take advantage of these new possibilites being the frst international palaeontology congress developed in a virtual environment. This online congress is pioneer in palaeontology, offering an exclusively virtual-developed environment to researchers all around the globe. The simplicity of this new format, giving international projection to the palaeontological research carried out by groups with limited economic resources (expensive registration fees, travel, accomodation and maintenance expenses), is one of our main achievements. This new format combines the benefts of traditional meetings (i.e., providing a forum for discussion, including guest lectures, feld trips or the production of an abstract book) with the advantages of the online platforms, which allow to reach a high number of researchers along the world, promoting the participation of palaeontologists from developing countries.

The depositional environments and hydrocarbon potentials were also interpreted. The total organic carbon concentrations in the studied samples ranged from 0.50% to 63.08%. The samples from Özyurt, Kayadibi, and Tarhanas contained types II and III kerogen, and those from Sökmen and Manas contained type III kerogen. The samples contained Co, Cs, Ga, Hf, Th, U, Y, Mo, Be, Cd, Sb, and La, with average values similar to those of standard brown coals. The samples showed average contents of Co, Ga, Nb, Rb, V, Y, Cu, Pb, Zn, As, Be, and Se, similar to those of other Turkish coals. The sediment source of Eocene samples in the five areas was characterized by rocks with intermediate or mafic geochemical characteristics. The terrigenous/aquatic ratio of coal and shaly coal samples of the areas in question is >1. The sterane distribution was 29C > C28 > C27 and C29 > C27 > C28 for the Özyurt and Tarhanas areas, respectively.

  • New Radiometric 40Ar–39Ar Dates and Faunistic Analyses Refine
    www.nature.com/scientificreports OPEN New radiometric 40Ar–39Ar dates and faunistic analyses refne evolutionary dynamics of Neogene vertebrate assemblages in southern South America Francisco J. Prevosti1,2*, Cristo O. Romano2,3, Analía M. Forasiepi2,3, Sidney Hemming4, Ricardo Bonini2,5, Adriana M. Candela2,6, Esperanza Cerdeño2,3, M. Carolina Madozzo Jaén2,7,8, Pablo E. Ortiz2,7, François Pujos2,3, Luciano Rasia2,6, Gabriela I. Schmidt2,9, Matias Taglioretti10,11,12, Ross D. E. MacPhee13 & Ulyses F. J. Pardiñas2,14,15 The vertebrate fossil record of the Pampean Region of Argentina occupies an important place in South American vertebrate paleontology. An abundance of localities has long been the main basis for constructing the chronostratigraphical/geochronological scale for the late Neogene–Quaternary of South America, as well as for understanding major patterns of vertebrate evolution, including the Great American Biotic Interchange. However, few independently-derived dates are available for constraining this record. In this contribution, we present new 40Ar/39Ar dates on escorias (likely the product of meteoric impacts) from the Argentinean Atlantic coast and statistically-based biochronological analyses that help to calibrate Late Miocene–Pliocene Pampean faunal successions. For the type areas of the Montehermosan and Chapadmalalan Ages/Stages, our results delimit their age ranges to 4.7–3.7 Ma and ca. 3.74–3.04 Ma, respectively. Additionally, from Buenos Aires Province, dates of 5.17 Ma and 4.33 Ma were recovered for “Huayquerian” and Montehermosan faunas. This information helps to better calibrate important frst appearances of allochthonous taxa in South America, including one of the oldest records for procyonids (7.24–5.95 Ma), cricetids (6.95– 5.46 Ma), and tayassuids (> 3.74 Ma, oldest high-confdence record).
