The Turonian concretionary phosphate-bearing bed outcropping NE of Srednya village consists of phosphate concretions and abundant phosphatized fauna, showing typical features of condensation and syn-sedimentary reworking. Key ammonite taxa indicate mixing of Collignoniceras woollgari and Subprionocyclus neptuni zones. The characteristics of burrows...

A dinoflagellate cyst biostratigraphy for the upper Campanian–lower Maastrichtian interval in the newly described Oslen-Krivodol section, northwest Bulgaria, is proposed. The dinocyst scheme comprises the zones of Areoligera coronata and Cerodinium diebelii, in ascending order, and illustrates the sharp transition between the Campanian and Maastric...

Inoceramid data were used to characterize the lower Maastrichtian strata in the Western Fore-Balkan (Bulgaria), based on the newly discovered Oslen Krivodol section. The upper part of the Kunino Formation yielded a well-defined inoceramid-bearing level. A number of characteristic taxa make up the inoceramid assemblage, including Cataceramus pallise...

The Upper Cretaceous succession (Coniacian to lowermost Maastrichtian, with focus on the Campanian) at Petrich, Central Srednogorie Zone in Bulgaria, is described and calibrated stratigraphically based on nannofossils, dinoflagellate cysts and inoceramids. The following standard nannofossil zones and subzones are identified: UC10–UC11ab (middle to...

The Kyunetsa section, 2.5 km west of Kosharevo, exposes mainly pelagic Upper Cretaceous marly limestones and marls of the Srednogorie Zone, part of the intermediate Balkanides in Bulgaria. The Melove Formation of Coniacian to early Campanian age involves a prominent Santonian-Campanian boundary interval of grey and reddish sediments, including CORB...

First record of early angiosperm pollen from the lower Aptian sediments in the Butovo section, Central North Bulgaria is documented. It is represented by monocolpate crotonoid grains attributed to the Stellatopollis genus and the species Stellatopollis barghoornii Doyle, Van Campo, Lugardon, 1975. The encountered sporomorph association also include...

Palynological and calcareous nannofossil investigations on samples from the basal part of the Gosau Group succession in three boreholes (Glinzendorf T1, Gänserndorf T3 and Markgraf Neusiedl T1) in the Vienna Basin provide calibrated age assessment of late Coniacian to early Campanian age for this thick non-marine to marginal-marine siliciclastic in...

The use of palynofacies analysis has been steadily increasing during the last decades. This stems from both commercial interests (i.e., hydrocarbon exploration) and academic research of past environments and studies of the global climate changes that took place during the Phanerozoic. In both commercial and academic contexts, there is a need for a...

A conference paper reviewing published research and preliminary data on the ongoing studies of a recently discovered late Santonian - early Campanian tetrapod fossil site in Western Bulgaria.

We present the inoceramid and dinoflagellate cyst record from the topmost Campanian-Maastrichtian strata of three key sections of the Western Fore-Balkan Mountains, northwest Bulgaria. The following inoceramid zones were recognized: "Inoceramus" redbirdensis Zone, Endocostea typica Zone, Trochoceramus radiosus Zone and "Inoceramus" ianjonaensis Zon...

Integrated palynological study provides new evidences to specify more precisely the chronostratigraphic extend of parts of the Byers Group, Livingston Island, Antarctica, than in previous palynological studies. It indicates the dinocyst Batioladinium reticulatum Range Zone for the upper part of President Beaches Formation, suggesting latest Berrias...

Palynological studies on parts of the Byers Group, Livingston Island have provided new data on its palynological content, palaeo-oceanographic setting and palaeoclimatic assessment. The Byers Group, exposed on the Byers Peninsula, comprises thick Upper Jurassic-Lower Cretaceous sedimentary and volcanic succession, deposited in marginal fore-arc env...

Brief conference report on a new Late Cretaceous tetrapod fossil site near the town of Tran (Western Srednogorie), Western Bulgaria, with notes on its dating and palaeoecology. Collected fossil material indicates presence of at least two groups of non-avian dinosaurs, crocodylomorph, and testudines.

In the area of the Western Fore-Balkan, integrated bio-stratigraphic studies based on inoceramids, ammonites and dinofllagelate cysts, have never previously been carried-out to date. The present study is the first attempt to draw the Campanian/Maastrichtian boundary by using these fossil groups into a newly discovered section near Reselets village....

Until recently, the fossil record of terrestrial Mesozoic tetrapods in Bulgaria was scarce, restricted to fragmentary remains of non-avian dinosaurs from the Maastrichtian limestones of the Kajlâka Formation (Mateus et al., 2010; Godefroit, Motchurova-Dekova, 2010). Herein were present preliminary data on a new Late Cretaceous fossil site near the...

Upper Barremian and lower Aptian dinoflagellate cyst assemblages have been documented for the first time from five ammonite-controlled sections in Central and Northeast Bulgaria. They include important biostratigraphical markers, such as Rhynchodiniopsis aptiana, Prolixosphaeridium parvispinum, Cerbia tabulata, Lithodinia stoveri and Ctenidodinium...

The palynological assemblages from two Albian-Cenomanian boundary sections in North Bulgaria are described. The samples analyzed yielded a diverse palynological content including dinoflagellate cysts and miospores. Based on dinocyst nutrient and productivity indices a phase of enhanced nutrient availability and high primary productivity is inferred...

Albian-Cenomanian grey-green marl succession crops out at several re- stricted outcrops north of Rabisha mound in Northwest Bulgaria. The contin- uous sequence near Tolovitsa karst spring is characterised by calcareous nan- nofossils and dinoflagellate cysts. It is subdivided in two nannofossil zones: Eiffellithus turriseiffelii and Lithraphidites...

The Ultrahelvetic Rehkogelgraben section of the Eastern Alps of Austria comprises a c. 5 m thick sequence of upper Cenomanian to lower Turonian pelagic sediments including black shales in a northwestern Tethyan paleogeographic setting.The following calcareous nannofossil events were recognized in stratigraphic order: The first occurrence (FO) of Qu...

On the west coast of Tierra del Fuego, south of Cabo Nariz, in Chile, Upper Cretaceous to Paleocene sedimentary successions of the Magallanes foreland basin crop out. The presence of dinoflagellate cysts, as well as radiometric U-Pb SHPJMP dating of detrital zircons, indicate that this succession ranges from the Campanian to Thanetian (Late Paleoce...

In the Rhenodanubian Flysch Zone of Austria, between the Aptian–Albian “Gault Flysch” and the Cenomanian–Turonian Reiselsberg Formation, an interval with predominant red shales (“Untere Bunte Schiefer”) occurs. In the Oberaschau section near Attersee (Upper Austria) a ca. 18-m-thick interval of alternating red and grey shales and marlstones with mi...

Berriasian and Valanginian dinocyst assemblages are documented from three boreholes in Northeast Bulgaria. In addition to conventional transmitted light microscopy, a selection of species has been studied in confocal laser scanning microscopy (CLSM). The novel method of CLSM is now applied for the first time to the morphological analysis and final...

Results of a combined palynological study of the continental to marine deposits of the Upper Cretaceous Gosau Group in the Northern Calcareous Alps (Austria) are presented. A framework for palynostratigra-phic correlation based on sporomorphs and dinoflagellate cysts is defined in the composite Gosau section (Upper Turonian-Maastrichtian) and compa...

The paper presents description and illustrations of 10 Normapolles species obtained from the conglomeratic formation near Panagyurishte and Strelcha and new for the Bulgarian palynoflora. They belong mainly to the genera Nudopollis, Oculopollis, Semioculopollis and Interporopollenites. The taxa are considered to be stratigraphically important. Thei...

Santonian and Campanian dinocyst and Normapolles assemblages are documented from three sections in Northern Bulgaria. Their successions are considered separately. Two distinct successive dinocyst zones are recognized within this interval: Dinogymnium denticulatum range zone (Santonian) and Senoniasphaera protrusa range zone (uppermost Santonian-Low...

A succession of outcrops in the region west of the town of Breznik has brought new biostratigraphic results concerning the Turonian Stage in the area. Integrated vertical distribution of ammonites, foraminifers, dinoflagellate cysts, pollen and spores is proposed for the first time in Bulgaria. This combined study enables the recognition of the thr...
