A monospecific assemblage of Globotalicypridea mirabilis sp. nov. is reported from the Maastrichtian of the Hateg Basin, Romania. This new species is the first ostracod taxa described from the famous dinosaur-bearing continental deposits of the Hateg Basin. G. mirabilis sp. nov. is characterized by large, finely punctate, and posteriorly strongly inflated carapace with a few papillae on the anterior margin. This new species was restricted exclusively

The Dej Tuff is an important stratigraphic marker in the Transylvanian Basin. However, its Early Badenian age is known only on biostratigraphical grounds so far. A number of radiometric dating techniques including K-Ar, Ar-Ar and fission-track have been used in order to constrain more precisely its age, allowing the calibration of the Transylvanian Basin's evolutionary models. Although individual dating methods could not provide a unique, reliable

Rare specimens of Ammodiscus are documented from Sarmatian (Middle Miocene) sandy-silty shales outcropping at Chinusu on the southeastern border of the Transylvanian Basin. These small, irregularly coiled and relatively coarsely agglutinated forms compare well morphologically to the modern species Ammodiscus gullmarensis Höglund, 1948 and are tentatively designated as Ammodiscus aff. gullmarensis. and are tentatively designated as Ammodiscus aff.

The Sarmatian foraminiferal assemblages from the southern Transylvanian Basin were described and interpreted in order to investigate space and time distribution of the different Sarmatian foraminiferal assemblages and species, and to determine the relationships between the foraminiferal assemblages and depositional environments. Our results have shown that every depositional environment can be characterized by specific foraminiferal assemblages which

The Transylvanian Basin is a mature hydrocarbon province of Romania characterized by two petroleum systems: Mesozoic (thermogenic) and Miocene (biogenic). An extensive outcrop-based sedimentological and micropaleontological study correlated to seismic and well data discusses the elements of the Miocene petroleum system. The facies associations are indicative of alluvial, fandelta, shallow- and deep-marine settings. These are grouped into four different

Deep-water agglutinated Foraminifera (DWAF) were recovered from Miocene to Pliocene sediments in 103 samples from IODP Hole M0002A on the Lomonosov Ridge. The First Occurrence of DWAF in Hole M0002A is observed just above the color change corresponding to the boundary between Lithological Subunits 1/4 and 1/5 in Core section –44X-1. The foraminiferal record of Hole M0002A consists entirely of agglutinated benthic species, largely sparse assemblages

Recent investigations of the Upper Badenian and Sarmatian of the Transylvanian Basin revealed particular, small sized planktonic foraminiferal assemblages. SEM investigation permitted more precise taxonomic interpretations of the planktonic species. The Late Badenian assemblage – with trochospiral, microperforate, and pustulose Tenuitellinae – occurring in relation to a transgressive event close to the end of the Badenian, makes possible an increased

Deep-water agglutinated Foraminifera (DWAF)are investigated from Miocene sediments recovered from ODP Hole 909C in the Fram Strait, Norwegian-Greenland Sea. We studied 125 samples from Cores 909C-50R to -103R, and recovered over 60 species of DWAF. The faunal succession in Hole 909C is subdivided into three assemblages based on the stratigraphic ranges of characteristic cosmopolitan taxa. These are: (1) a diverse Reticulophragmium amplectens - Reophanus
