November 2000 Ammonitenfaunen des hohen Oberconiac und Santon in Westfalen William James Kennedy und Ulrich Kaplan* K u r z f a s s u n g: Die Ammonitenfaunen des hohen Oberconiacs und Santons des Münsterländer Beckens werden systematisch und stratigraphisch revidiert. Insgesamt lassen sich 32 Arten nachweisen, die sich auf 20 Gattungen verteilen. Neben dem Typmaterial von SCHLÜTER (1871-1876) werden auch die von RIEDEL (1931 ), SCHÖNFELD (1985) und LOMMERZHEIM (1995) abgebildeten Exemplare teilweise neu beschrieben und abgebildet. Als neue Art wird Kitchinites scheeri aus dem Oberconiac von Dortmund beschrieben. Die Ammonitenvorkommen werden im Kontext der lnoceramen- und wo möglich der Belem­ niten- und Crinoidenstratigraphie dokumentiert. Es wird eine Ammonitenstratigraphie für das hohe Oberco­ niac und Santon des Münsterländer Beckens vorgeschlagen. Die Texanites pseudotexanus-Zone reicht von der obersten M. subquadratus-Zone bis zur Coniac/Santon-Grenze. Die Kitchinites emscheris-Zone ent­ spricht dem Unter- und Mittelsanton. Das Obersanton entspricht der Boehmoceras arcu/us-Zone. A b s t r a c t: The high Coniacian and Santonian ammonite faunas of the Münster Basin are systemati­ cally and stratigraphically revised. They comprise 32 species, referred to 20 genera. In addition to SCHLÜ• TER's (1871-1876) type-material, the accessible specimens figured by RIEDEL (1931) and LOMMERZ­ HEIM (1995) are redescribed and partially refigured. The ammonite occurrences are documented in the context of inoceramid and, where possible, belemnite and crinoid stratigraphy. An ammonite stratigraphy for the uppermost Upper Coniacian and Santonian of the Münster Basin is proposed. A Texanites ( Texanites) pseudotexanus-Zone extends from the uppermost M. subquadratus-Zone to the Coniacian/Santonian boundary. The Kitchinites emscheris-Zone comprises the Lower and Middle Santonian. The Upper Santo­ nian corresponds to the Boehmoceras arculus-Zone. lnhaltesverzeichnis 1 .

Warszawa. Five heteromorph ammonite taxa belonging to the Nostoceratidae and the Diplomoceratidae are described from the Upper Turonian and Lower Coniacian of northern Germany and Saxony. The investigation serves the presentation of additional material of Hyphantoceras flexuosum, Neocrioceras paderbornense and Scalarites turoniense that are rarely documented in northern Germany and Saxony. Furthermore, one new species, Hyphantoceras ernsti sp. n., is introduced. One taxon is described in open nomenclature as nostoceratid gen. et sp. indet.

  • Ammonite Faunal Dynamics Across Bio−Events During the Mid− and Late Cretaceous Along the Russian Pacific Coast
    Ammonite faunal dynamics across bio−events during the mid− and Late Cretaceous along the Russian Pacific coast ELENA A. JAGT−YAZYKOVA Jagt−Yazykova, E.A. 2012. Ammonite faunal dynamics across bio−events during the mid− and Late Cretaceous along the Russian Pacific coast. Acta Palaeontologica Polonica 57 (4): 737–748. The present paper focuses on the evolutionary dynamics of ammonites from sections along the Russian Pacific coast dur− ing the mid− and Late Cretaceous. Changes in ammonite diversity (i.e., disappearance [extinction or emigration], appear− ance [origination or immigration], and total number of species present) constitute the basis for the identification of the main bio−events. The regional diversity curve reflects all global mass extinctions, faunal turnovers, and radiations. In the case of the Pacific coastal regions, such bio−events (which are comparatively easily recognised and have been described in detail), rather than first or last appearance datums of index species, should be used for global correlation. This is because of the high degree of endemism and provinciality of Cretaceous macrofaunas from the Pacific region in general and of ammonites in particular. Key words: Ammonoidea, evolution, bio−events, Cretaceous, Far East Russia, Pacific. Elena A. Jagt−Yazykova [[email protected]], Zakład Paleobiologii, Katedra Biosystematyki, Uniwersytet Opolski, ul.

Programme Fossils and Strata is an international series of monographs and memoirs in palaeontology and stratigraphy, published in cooperation between the Scandinavian countries. It is issued in Numbers with individual pagination. Fossils and Strata forms part of the same structured publishingprogramme as the journals Lethaia and Boreas. These two journals are fully international and accept papers within their respective sectors of sciencewithout nationallimitations or preferences. Fossils and Strata, however, is an outlet for more comprehensive systematic and regional monographs emanating primarily from the five countries of Norden. Contributions from other countries may also be included if this series is deemed appropriate with regard to distribution and availability. Articles can normally only be accepted if they are heavily subsidized by the national Research Council in their country of origin or by other funds. All income is re-invested in forthcoming numbers of the series. Although articles in German and French may be accepted, the use of English is stronglypreferred.

    ©Naturhistorisches Museum Wien, download unter www.biologiezentrum.at Ann. Naturhist. Mus. Wien, Serie A 112 627-658 Wien, Juni 2010 Barremian rhyncholites (Lower Cretaceous Ammonoidea: calcified upper jaws) from the Serre de Bleyton (Département Drôme, SE France) By Wolfgang RIEGRAF1 & Gero MOOSLEITNER2 (With 2 figures, 2 plates and 1 table) Manuscript submitted on June 10th 2009, the revised manuscript on January 19th 2010 Abstract Seven calcified upper jaw tips of Rhynchoteuthis astieriana D’ORBIGNY and Palaeoteuthis infira (SHIMANSKY) from the Serre de Bleyton section (Dépt. Drôme, SE France) were redeposited from an outer shelf into an upper slope (upper bathyal) environment embedded in a highly fossiliferous Barremian bioclastic limestone. They represent a low diverse and poor preserved small Barremian pelagic rhyncholite fauna, also described from a few Tethyan and Alpine localities between Cuba, the Crimea, and the Caucasus. Rhynchoteuthis and Palaeoteuthis may most probably represent calcified tips of upper jaws of various taxa of Tethyan ammonites, e.g. of the Phylloceratina (Phyl- loceras, Sowerbyceras), Lytoceratina (Tetragonitidae), and/or some Ammonitina (Arnioceras, Eleganticeras, Hildoceras, Aconeceras). But due to their scarcity, poor preservation, and the allochthonous occurrence, the Serre de Bleyton rhynchoteuthids do not contribute further new knowledge to taxonomy, palaeoecology, stratigraphy or basinal history. Kurzfassung Sieben kalkige Oberkieferspitzen – Rhynchoteuthis astieriana D’ORBIGNY und Palaeoteuthis infira (SHIMANSKY) aus einem Profil der Serre de Bleyton (Dépt. Drôme, SE-Frankreich) – gelangten vom Schelf durch Umlagerung in ein oberbathyales Milieu des oberen Kontinentalabhangs, in einen äußerst fossilreichen bioklastischen Kalkstein. Solche geringdiversen und mäßig erhaltenen pe- lagischen Rhyncholithenfaunen des Barremium sind auch von vereinzelten tethyalen und alpinen Fundorten zwischen Kuba, der Krim und dem Kaukasus beschrieben.

This suggests that both the sedimentary basins of the Sanchu Cretaceous and the Atokura and its equivalent formations were provided deposits from nearly the same rocks in the provenance not in the same age, but in the different age.

A cyclic mode of shell growth and its implications in a Late Cretaceous heteromorph ammonite Polyptychoceras pseudogaultinum (yokoyama) TAKASHI OKAMOTO and MAKOTO SHIBATA Department of Earth Sciences, Ehime University, Bunkyo-cho 2-5, Matsuyama, 790 Japan.

Received 18 May, 1996: Revised manuscript accepted 20 December 1996 Abstract Polyptychoceras, a Cretaceous heteromorph ammonite genus, is characterized by a trom­ bone-like shell called a "hamitoid" shell. In order to clarify the shell-forming mechanism, a large sample, which consists of more than 320 specimens of P. pseudogaultinum (yokoyama) obtained from the Upper Santonian of Hokkaido, was biometrically analyzed. Besides the shell coiling, cyclic changes of growth pattern are recognized by the analyses of the shell ornamentation, the relative growth rate of shell height, and the distance between septa. Intermittent shell growth, which was also deduced from the ontogenetic stage distribution in the population samples, is probably the cause of such peculiar shell coiling. Also, we carried out some computer simulations to reconstruct hydrostatically the ontogenetic change of the living attitude of P. pseudogaultinum. It is suggested that the rate of absolute shell growth possibly depends on the living attitude of this ammonite in the water column; the shell grows slowly when the shell aperture faces upward, and grows rapidly when the aperture faces in other directions. It is likely that every individual of this ammonite spent most of its life time with an upward-facing aperture.
