Just out @ Lethaia The contribution of fossils to chronostratigraphy, 150 years after Albert Oppel Author(s) Marco Balini, Annalisa Ferretti, Stan Finney, Simonetta Monechi Abstract: The 150th anniversary of the death of Albert Oppel (1831–65) provided the opportunity to celebrate this outstanding stratigrapher with a Thematic Issue dedicated to the importance of fossils for dating and correlating of sedimentary rocks. In this issue, we analyse Oppel’s significant contribution to modern chronostratigraphy, before

Just out | New data on microbiota of the Middle Volgian substage in the Loino Section (Kirov oblast) @ Stratigraphy and Geological Correlation

Just out @ Stratigraphy and Geological Correlation New data on microbiota of the Middle Volgian substage in the Loino Section (Kirov oblast) Author(s) M. A. Ustinova, E. M. Tesakova Abstract: The calcareous nannoplankton was established for the first time in Upper Volgian deposits of the Loino Section (Kirov oblast). Here, single coccolites of representatives of genus Watznaueria of wide stratigraphic and geographic distributions dominate. Representatives of genus Zuegrhabdotus are less common, whereas species of genus Polypodorhabdus are rare. The taxonomic composition of

Just out @ Stratigraphy and Geological Correlation New data on stratigraphy (palynomorphs, ostracods, paleomagnetism) of Cenozoic continental deposits of the Ishim plain, Western Siberia Author(s) O. B. Kuzmina, Z. N. Gnibidenko, L. B. Khazin, I. V. Khazina Abstract: New micropaleontological and paleomagnetic data were obtained by studying core samples of Cenozoic continental deposits from two boreholes drilled in the south of Tyumen oblast (Western Siberia). Palynological assemblages in deposits of the Tavda (upper part), Novomikhailovka, Turtas, Abrosimovka, Tobolsk, Smirnovka, and Suzgun formations

Just out @ Cretaceous Research Integrated biostratigraphy and palaeoenvironmental interpretation of the Upper Cretaceous to Paleocene succession in the northern Moldavidian Domain (Eastern Carpathians, Romania) Author(s) Daniel Ţabără, Hamid Slimani, Silvia Mare, Carmen Mariana Chira Abstract: This study of the upper Maastrichtian to Danian sedimentary succession from the northern part of the Romanian Eastern Carpathians (Varniţa section) aims to establish an integrated biostratigraphy based on calcareous nannofossils, organic-walled dinoflagellate cysts (dinocysts) and

Just out @ Lethaia Calcareous nannofossil biostratigraphy: historical background and application in Cenozoic chronostratigraphy Author(s) Claudia Agnini, Simonetta Monechi, Isabella Raffi Abstract: Calcareous nannofossils are considered one of the most powerful biostratigraphical tool in marine carbonate sediments especially in open ocean settings. Their origination goes at least as far back as the Triassic (ca. 220 Ma) when they first biomineralized and produced calcite skeletons. Since then, they have evolved rapidly showing

Just out | First report of Devonian bactritids (Cephalopoda) from South America: paleobiogeographic and biostratigraphic implications @ Journal of Paleontology

Just out @ Journal of Paleontology First report of Devonian bactritids (Cephalopoda) from South America: paleobiogeographic and biostratigraphic implications Author(s) Marcela Cichowolski, Juan J. Rustán Abstract: Devonian bactritids are described for the first time from South America. They come from siliciclastic rocks of the Talacasto Formation in the Precordillera Basin, west-central Argentina. The host strata span the Lochkovian–Emsian and contain other non-ammonoid cephalopods as well, thus refuting the alleged virtual absence

Just out | The evolution of Oppel's ‘Macrocephalusbett’ (Callovian, Middle Jurassic) @ Lethaia

Just out @ Lethaia The evolution of Oppel’s ‘Macrocephalusbett’ (Callovian, Middle Jurassic) Author(s) Eckhard Mönnig Abstract: In his basic work of 1856–1858, Albert Oppel subdivided his ‘Juraformation’ into eight stages and 32 zones. There is a long history of confusion as to the meaning of Oppel’s zones. Using his ‘Macrocephalusbett’ and his ‘Zone des Amm. macrocephalus’, it is explained how his concept has been developed until today. Both and also

Just out @ Journal of Paleolimnology Reconstructing recent environmental changes using non-biting midges (Diptera: Chironomidae) in two high mountain lakes from northern Patagonia, Argentina Author(s) Fernanda Montes de Oca, Luciana Motta, María Sofía Plastani, Cecilia Laprida, Andrea Lami, Julieta Massaferro Abstract: Remote lakes of northern Patagonia are ideal sites for examining climate- and non-climate-driven changes in aquatic ecosystems because there is little evidence of human influence and there is no detailed

Just out @ Bulletin of Geosciences Famennian (Upper Devonian) conodont zonation: revised global standard Author(s) Spalletta C, Perri MC, Over DJ, Corradini C Abstract: The revision of the Famennian part of the “Late Devonian Standard Conodont Zonation” is based on the in-equivalence between biozones and time, and the rejection of the presumed single phyletic concept on which the previous zonation was based. It is also intended to simplify the zonation,

Just out @ Palaeogeography, Palaeoclimatology, Palaeoecology The Pannonian C hipparions from the Vienna Basin Author(s) Raymond L. Bernor, Ursula B. Göhlich, Mathias Harzhauser, Gina M. Semprebon Abstract: The “Hipparion” Datum has been recognized as being a key geochronologic marker for early late Miocene Eurasian and African horizons. The Vienna Basin Pannonian C hipparions are the stratigraphically oldest (basal MN9, ca. 11.4–11.0 Ma), and we contend herein, the most primitive of all Old
