The aim of the study was taxonomic, morphological, ecological and stratigraphic characterization marine invertebrate groups from localities Wiek Wysoka (Krakow-Częstochowa Upland) Gnieździska (Świętokrzyskie Mountains). All these three were unused quarries where limestone once mined. material consisted a total 756 fossils collected by author studied sites or constituting part collections Depart...

Research subject. For the first time, results of a study hydrothermal-bacterial carbonate structures and shell bank brachiopods on surface effusive sequence Late Triassic Tessel paleovolcano are presented. Methods. Petrographic thin sections were studied using an Olympus BX 5 microscope with DP 12 camera. Geochemical investigations performed according to conventional methodology by inductively ...

Abstract Since the 1980s, Upper Jurassic lithographic limestone of Causse Méjean (southern France) has been known by local naturalists to yield fossils. However, until beginning 21st century, this plattenkalk remained largely undersampled and scientifically underestimated. Here, we present results two decades prospection sampling in Drigas Nivoliers quarries. We provide first palaeontological i...

The latest Triassic to earliest Jurassic transition has been widely studied due the occurrence of a major global extinction associated with hyperthermal event in this interval. Furthermore, number distinct geochemical events carbon cycle can be recognised stable-isotope record across boundary interval at many localities. Two fully-cored boreholes from East Antrim Northern Ireland (Carnduff-1 an...

The following forms are recorded from the Koppeh-Dagh Basin: Heteroceras cf. colchicus Djanelidze, Heteroceras spp., Martelites cf. tenuicostatus (Kakabadze), Martelites securiformis (Simonovich, Bastevich and Sorokin), Martelites cf. tinae (Eristavi), Martelites sp.1, Martelites sp. 2, Argvethites sp., Imer...
