    Sinemurian biostratigraphy of the Tannscharten section near Reichraming (Lower Jurassic, Schneeberg Syncline, Northern Calcareous Alps) Lukeneder, Petra (Natural History Museum, Vienna, AUT); Lukeneder, Alexander (Natural History Museum, Vienna, AUT) Lower Jurassic pelagic to hemipelagic sediments are known to form a significant element of the northernmost tectonic units of the Northern Calcareous Alps (e.g. Ternberg-, Reichraming-, Frankenfels-, and Lunz-nappes). In the Reichraming Nappe comprising the Lower Jurassic Tannscharten locality, Liassic cephalopod-bearing deposits are recorded in a deep water limestone facies, the Allgäu Formation (= “Lias Fleckenmergel”). Lower Jurassic ammonites were collected from deep water limestone of the Tannscharten section southwest of Reichraming (Upper Austria, Northern Calcareous Alps). The outcrop provides a rich Upper Sinemurian (Lower Jurassic) ammonite fauna of the Allgäu Formation. The area is situated in the westernmost part of the Schneeberg Syncline in the north of the Reichraming Nappe (High- Bajuvaric Unit). The ammonite fauna consists of seven different genera, each apparently represented by 1-2 species.

I. Cuza” University of Iaşi, Faculty of Geography and Geology, Department of Geology, 20A Carol I Blv., 700505 Iaşi, Romania Abstract In 1900, Uhlig proposed five new species of ammonites and one brachiopod species, Early Jurassic in age, from the Praşca Klippe (Rarău Syncline, Eastern Carpathians). “Rhacophyllites” bucovinicus is the only phylloceratid described, which displays a very wide umbilicus and a unique small keel near the aperture. Following Uhlig’s holotype, new specimens were found, only recently, and a topotype series was formed. After the Uhlig’s holotype, new specimens were found only recently forming a topotype series. Previously quoted records in different areas (e.g. Bocskorbergs – Bakony Mountains, Hungary; Montagna del Casale – Sicily, Italy; Hierlatz – Northern Calcareous Alps, Austria; Male Karpaty – Western Carpathians, Slovakia ) are discussed, as well as the modern assignment of the species.

The revised material mostly comes from the preserved collections of HAUER (1853, 1854 and partly 1856) and GEYER (1886) at the GBA. Besides that we also studied own material. The assembla­ ge of ammonites is relatively rich in species as testified by arround 40 described species, from which there is one new species. With regard to the fact that at locality Hierlatz the fauna occurs in neptunic dykes, horizoned collections cannot be gathered out here. On the bases of as­ semblages of ammonites presented here we distinguished five ammonite horizons, which represent the Sinemurian , Lotharingian and Lower Carixian too.

    Palaeodiversity 1: 133–140; Stuttgart, 30.12.2008. 133 Juraphyllites mimatensis (D’ORBIGNY , 1845) (Ammonoidea: Phylloceratida), a Tethyan immigrant in the Upper Pliensbachian of Franconia (Jurassic, Southern Germany) HELMUT KEUPP & GÜNTER SC H WEIGERT Abstract Two well-preserved small-sized specimens of phylloceratoid ammonites are reported from the Late Pliensba- chian Spinatum Zone of Franconia. They are assigned to Juraphyllites (cf.) mimatensis (D’ORBIGNY , 1845) and re- garded as Tethyan immigrants. Due to their very similar early ontogenetic stages it seems impossible to distinguish tiny juveniles of Juraphyllites mimatensis (D’ORBIGNY , 1845) from those of contemporaneous Meneghiniceras exi- mium (V. HAUER ). Keywords: Phylloceratina, Early Jurassic, palaeobiogeography, immigration, Franconia, Germany. Zusammenfassung Zwei gut erhaltene kleinwüchsige Exemplare phylloceratoider Ammoniten werden aus der Spinatum-Zone des Ober-Pliensbachium von Franken beschrieben. Sie werden zu Juraphyllites (cf.) mimatensis (D’ORBIGNY , 1845) ge- stellt und als tethyale Einwanderer angesehen. Wegen ihrer sehr ähnlichen frühontogenetischen Stadien erscheint es praktisch unmöglich, sehr kleine Individuen von Juraphyllites mimatensis (D’ORBIGNY , 1845) von solchen des gleich zeitig vorkommenden Meneghiniceras eximium (V. HAUER ) zu unterscheiden. 1. Introduction 2.

  • The Mesozoic Stratigraphy and Ammonite Fauna of Ladik-Akdag (Samsun) Territory
    INTERNATIONAL SCIENTIFIC AND VOCATIONAL JOURNAL (ISVOS JOURNAL) Vol.:2 Issue:2 Date:December 2018 Received:29.11.2018 Accepted:17.12.2018 Final Version:25.12.2018 ISVOS Journal 2018, 2(2):148-155 The Mesozoic Stratigraphy and Ammonite Fauna of Ladik-Akdag (Samsun) Territory Özlem Topraka,1, Mehmet Akyazı b a Department of Tokat Vocational Higher School of Technical Sciences, Tokat Gaziosmanpaşa University, Tokat ,60100,Turkey b Department of Geological Engineering, Cumhuriyet University, Sivas, 58100,Turkey Abstract This paper presents , it is aimed to reveal Mesozoic stratigraphy of Ladik-Akdag region in detail. In the study area, rocks formed in various facies which are different from each other are observed. On the basis of the region, Permo-Triassic aged limestones and Permian aged limestones, mostly in the block, are located in the north, although they have basal rocks in the ages of Permo-Triassic and autochthonous in the south. The cover rocks begin with Liassic aged clastics covering the base rocks and the Dogger aged rocks consisting of metamorphic and volcanic conglomerates and recrystallized limestones. Upper Jurassic-Lower Cretaceous aged shallow marine and Tithonic facies-developed limestones are unconformably overlying Dogger rocks. In the study area, whereas the lower levels of the Upper Cretaceous are composed of sandstone-marly intercalated flysch and limestones, Maastrichtian consists of rocks in the volcano-flysch facies. Within the pelagic mudstones belonging to the unit, Pseudocyclammina liasica Hottinger, Triloculina sp., Involutina sp., Quinqueloculina sp., and Pentacirinus sp. Fossils have been also identified in addition to such ammonites as Phylloceras sp., Calliphylloceras sp. Ameltheus sp., Oxycerites sp., Juraphyllites sp.
