Two new graptolite assemblages are identified from discrete intervals within the Phu Ngu Formation, Na Ri District, Bac Kan Province, north-east Vietnam. The graptolites occur in laminated mud/siltstones thought to be distal turbidite deposits. A low-diversity diplograptid sensu lato assemblage occurs mud-rich layers that interlaminated with silty and sandy horizons containing dendroid Dictyone...

Ostracods as bioindicators are extremely useful for reconstructing palaeoenvironment and palaeoclimate can also indicate the provenance of sediments materials, example, in studies on ancient commercial networks. small crustaceans that live almost all aquatic habitats, both natural man-made. Due to their calcitic carapace, they have high fossilization potential, use geoarchaeology has been stead...

At Podsused near Zagreb, in an abandoned surface excavation of cement marls, near Kostanjek (Fig. 1) an 83 m thick lithostratigraphical column was investigated comprising layers of Sarmatian and Pannonian age. Five lithofacies units (A, AB, B, C, D) were separated on the basis of their structural-petrographic characteristics. From layers with greater concentrations of fossils, a rich community ...

Microfossils present in Quaternary micrites from Serra da Bodoquena, Mato Grosso do Sul State, Brazil, are here described for the first time. The studied taxa are: a) ostracods: Candona sp., Candonopsis sp., Cyclocypris sp., Cypria sp., Cypridopsis sp., Notodromas sp., Ilyocypris sp., Cyprideis sp., Wolburgiopsis cf. chinamuertensis (Musacchio 1970), Darwinula sp. and 5 morphotypes; b) microgas...

the upper cretaceous thick bedded succession in badamouyeh mountain in honooj area shows the late cenomanian-santonian stages. also, these deposits are well exposed in the south-west of bibihayat and south of cheshmah gaz village. in the studied section, lower and upper honooj green marls (informal) with intercalation of exogyroferous shaly limestone are overlain by thick bedded limestones and ...

The abundance and higher taxonomic composition of epizooic metazoan meiobenthic communities associated with mussel and tubeworm aggregations of hydrocarbon seeps at Green Canyon, Atwater Valley, and Alaminos Canyon in depths between 1400 and 2800 m were studied and compared to the infaunal community of non-seep sediments nearby. Epizooic meiofaunal abundances of associated meiobenthos living in...

The benthic ostracods of Red Sea Egypt have received little attention in ecological studies. Temperature, depth, salinity, dissolved oxygen, pH, conductivity, and other environmental variables all an impact on ostracods. This study aimed to determine the influence parameters distribution by determining similarity dissimilarity between eight collection sites, investigating regional form accompli...
