The Capitanian (Permian) Kamura Cooling Event
Palaeoworld 16 (2007) 16–30 Research paper The Capitanian (Permian) Kamura cooling event: The beginning of the Paleozoic–Mesozoic transition Yukio Isozaki a,∗, Hodaka Kawahata b, Kayo Minoshima c a Department of Earth Science and Astronomy, The University of Tokyo, Komaba, Meguro, Tokyo 153-8902, Japan b Graduate School of Frontier Sciences and Ocean Research Institute, The University of Tokyo, Minamidai, Nakano, Tokyo 164-8639, Japan c Geological Survey of Japan, AIST, Tsukuba 305-8567, Japan Received 4 January 2007; received in revised form 12 May 2007; accepted 15 May 2007 Available online 25 May 2007 Abstract 13 The Capitanian (late Guadalupian) high positive plateau interval of carbonate carbon isotope ratio (␦ Ccarb) was recognized lately in a mid-Panthalassan paleo-atoll limestone in Japan as the Kamura event. This unique episode in the late-middle Permian indicates high productivity in the low-latitude superocean likely coupled with resultant global cooling. This event ended shortly before the Guadalupian–Lopingian (middle-late Permian) boundary (ca. 260 Ma); however, its onset time has not been ascertained previously. Through a further analysis of the Wordian (middle Guadalupian) to lower Capitanian interval in the same limestone at 13 Kamura in Kyushu, we have found that the ␦ Ccarb values started to rise over +4.5‰ and reached the maximum of +7.0‰ within the Yabeina (fusuline) Zone of the early-middle Capitanian. Thus the total duration of the Kamura event is estimated over 3–4 million years, given the whole Capitanian ranging for 5.4 million years. This 3–4 million years long unique cooling event occurred clearly after the Gondwana glaciation period (late Carboniferous to early Permian) in the middle of the long-term warming trend toward the Mesozoic. -

15 International Symposium on Ostracoda
Berliner paläobiologische Abhandlungen 1-160 6 Berlin 2005 15th International Symposium on Ostracoda In Memory of Friedrich-Franz Helmdach (1935-1994) Freie Universität Berlin September 12-15, 2005 Abstract Volume (edited by Rolf Kohring and Benjamin Sames) 2 ---------------------------------------------------------------------------------------------------------------------------------------- Preface The 15th International Symposium on Ostracoda takes place in Berlin in September 2005, hosted by the Institute of Geological Sciences of the Freie Universität Berlin. This is the second time that the International Symposium on Ostracoda has been held in Germany, following the 5th International Symposium in Hamburg in 1974. The relative importance of Ostracodology - the science that studies Ostracoda - in Germany is further highlighted by well-known names such as G.W. Müller, Klie, Triebel and Helmdach, and others who stand for the long tradition of research on Ostracoda in Germany. During our symposium in Berlin more than 150 participants from 36 countries will meet to discuss all aspects of living and fossil Ostracoda. We hope that the scientific communities working on the biology and palaeontology of Ostracoda will benefit from interesting talks and inspiring discussions - in accordance with the symposium's theme: Ostracodology - linking bio- and geosciences We wish every participant a successful symposium and a pleasant stay in Berlin Berlin, July 27th 2005 Michael Schudack and Steffen Mischke CONTENT Schudack, M. and Mischke, S.: Preface -

Email: [email protected] Manuscript received: October 2011, accepted: June 2012 Abstract We report here the addition of two rare mosasaur taxa to the Maastrichtian marine amniote fauna of Angola, both of which are also found in northern Europe. The new specimens include a dentary fragment referable to the large carnivore Prognathodon cf. saturator and an isolated tooth of the small durophage Carinodens belgicus. Both were recovered from Maastrichtian outcrops in southern Angola in 2011. Additionally, a complete posterior mandibular unit of a large mosasaur from the type Maastrichtian of the Netherlands, collected some time prior to 1879 and previously identified as ‘Mosasaurus giganteus’, is described and reassigned here to Prognathodon saturator; historical issues surrounding the taxonomic attribution of this specimen are clarified. The new material extends the known geographic distribution of Prognathodon saturator and Carinodens belgicus. Keywords: Mosasauridae, Prognathodon, Carinodens, Maastrichtian, Angola, the Netherlands Introduction Limburg Province, the Netherlands); the holotype is now housed in the collections of the Natuurhistorisch Museum In recent years our knowledge of the marine reptile fauna of Maastricht (NHMM1998-141). -
A Giant Chelonioid Turtle from the Late Cretaceous of Morocco with a Suction Feeding Apparatus Unique Among Tetrapods
OPEN 3 ACCESS Freely available online © PLOSI o - A Giant Chelonioid Turtle from the Late Cretaceous of Morocco with a Suction Feeding Apparatus Unique among Tetrapods Nathalie Bardet1*, Nour-Eddine Jal ¡I2, France de Lapparent de Broin1, Damien Germain1, Olivier Lambert3, Mbarek Amaghzaz4 1 CNRS UMR 7207, Département Histoire de la Terre, Muséum National d'Histoire Naturelle, Paris, France, 2 Cadi Ayyad University, Faculty of Sciences Semlalia, Department of Earth Sciences, Vertebrate Evolution and Palaeoenvironnements, Marrakech, Morocco, 3 Institut Royal des Sciences Naturelles de Belgique, Département de Paléontologie, Bruxelles, Belgium, 4 Office Chérifien des Phosphates, Centre Minier de Khouribga, Khouribga, Morocco Abstract Background: Secondary adaptation to aquatic life occurred independently in several amnlote lineages, Including reptiles during the Mesozoic and mammals during the Cenozoic. These evolutionary shifts to aquatic environments imply major morphological modifications, especially of the feeding apparatus. Mesozoic (250-65 Myr) marine reptiles, such as ichthyosaurs, plesiosaurs, mosasaurid squamates, crocodiles, and turtles, exhibit a wide range of adaptations to aquatic feeding and a broad overlap of their tooth morphospaces with those of Cenozoic marine mammals. However, despite these multiple feeding behavior convergences, suction feeding, though being a common feeding strategy In aquatic vertebrates and in marine mammals In particular, has been extremely rarely reported for Mesozoic marine reptiles. Principal Findings: A relative of fossil protostegid and dermochelyoid sea turtles,Ocepechelon bouyai gen. et sp. nov. is a new giant chelonioid from the Late Maastrichtian (67 Myr) of Morocco exhibiting remarkable adaptations to marine life (among others, very dorsally and posteriorly located nostrils). The 70-cm-longOcepechelon skull of not only makes it one of the largest marine turtles ever described, but also deviates significantly from typical turtle cranial morphology. -

Laboratory Primate Newsletter
LABORATORY PRIMATE NEWSLETTER Vol. 45, No. 3 July 2006 JUDITH E. SCHRIER, EDITOR JAMES S. HARPER, GORDON J. HANKINSON AND LARRY HULSEBOS, ASSOCIATE EDITORS MORRIS L. POVAR, CONSULTING EDITOR ELVA MATHIESEN, ASSISTANT EDITOR ALLAN M. SCHRIER, FOUNDING EDITOR, 1962-1987 Published Quarterly by the Schrier Research Laboratory Psychology Department, Brown University Providence, Rhode Island ISSN 0023-6861 POLICY STATEMENT The Laboratory Primate Newsletter provides a central source of information about nonhuman primates and re- lated matters to scientists who use these animals in their research and those whose work supports such research. The Newsletter (1) provides information on care and breeding of nonhuman primates for laboratory research, (2) dis- seminates general information and news about the world of primate research (such as announcements of meetings, research projects, sources of information, nomenclature changes), (3) helps meet the special research needs of indi- vidual investigators by publishing requests for research material or for information related to specific research prob- lems, and (4) serves the cause of conservation of nonhuman primates by publishing information on that topic. As a rule, research articles or summaries accepted for the Newsletter have some practical implications or provide general information likely to be of interest to investigators in a variety of areas of primate research. However, special con- sideration will be given to articles containing data on primates not conveniently publishable elsewhere. General descriptions of current research projects on primates will also be welcome. The Newsletter appears quarterly and is intended primarily for persons doing research with nonhuman primates. Back issues may be purchased for $5.00 each. -
