The Tritoechiidae are redefined following study of nine species of the genera Tritoechia, Eremotoechia, Martellia Pomatotrema, Protambonites and Korinevskia nov. gen. in Kazakhstanian brachiopod faunas from the upper Tremadoc to lower Caradoc. Six species are new: Tritoechia crassa, T. tokmakensis, Eremotoechia inchoata, E. spissa, Martellia reliqua and Pomatotrema fecunda. In key characters of shell...
Four previously undescribed dinoflagellate species were encountered during a detailed biostratigraphic analysis of the Miocene Berchem Formation in northern Belgium: Ataxiodinium scaldemense nov. sp., Operculodinium? borgerholtense nov. sp., Bitectatodinium heistense nov. sp. and Pyxidinopsis brabantiana nov. sp. A formal description and assessment of the stratigraphic ranges of the new species are...
The ammonites collected in the Upper Cenomanian — Middle Turonian rocks of ‘Anse de l'Arène’ bay near Cassis (SE France) are described in this paper. Despite the poor preservation, the identified taxa allow to recognize the Late Cenomanian Metoicoceras geslinianum and Neocardioceras judii Zones and the Early Turonian Mammites nodosoides and (probably) the Middle Turonian Collignoniceras woollgari...
This systematic study considers twenty-four gastropod species recovered in the Upper Aalenian-Lower Bajocian sediments of the Central High Atlas. Twenty-one species belong to archaeogastropod groups and three species are assigned to two caenogastropod families. A new genus, Sadkia nov. gen. (family Eucyclidae), and two new species, Sadkia richensis nov. sp. and Pirper ouchenensis nov. sp., are described...
Recent studies on Upper Cenomanian-Lower Turonian outcrops from Cassis area allow to build a biolithostratigraphic framework from platform (La Bédoule section) to basin deposits (Cassis section), based on ammonites, planktonic foraminifera, inoceramids, rudists and ostracods. Four ammonite Zones are documented: the Late Cenomanian Geslinianum and Juddii Zones; the Early Turonian Nodosoides and, possibly,...
Brachiopods from the Selong Group at the Selong Xishan section indicate a typical Peri-Gondwanan affinity, but possibly a rapid invasion of tropical/subtropical Tethyan elements into the Himalayan region at the very end of Permian. A brief analysis of taphonomy and composition of the Selong fauna indicate that Selong Xishan lay on the shallow continental shelf near shore and brachiopods suffered substantial...
