    At Ocean Drilling Program Hole C in the Southern Indian Ocean, a total of Late Cretaceous dinoflagellate taxa were encountered in 38 productive samples from Cores CR through CR ( mbsf). Four provisional dinoflagellate assemblage zones and five subzones were recognized based on the character of the.

Jurassic and Lower Cretaceous palynomorph assemblages are described from the Cape Flora Section and compared with assemblages recorded from Svalbard, East Greenland and Arctic Canada. The quantitative distribution of palynomorphs and palynodebris has also been estimated.

Preservation is good, and from the six samples investigated, 41 species of dinoflagellate cysts, acritarchs, pollen. A Preliminary Dinoflagellate Zonation of the Uppermost Jurassic and Lower Part of the Cretaceous, Canadian Arctic, and Possible Correlation in the Western Canada Basin.

The upper Dongrong Formation, containing Buchia fischeriana and dinoflagellate cyst assemblage Oligosphaeridium pulcherrium, can be correlated approximately with the whole of the Dong’anzhen Formation (Table 1, cols 1–2) since the index species, Buchia fischeriana, is common to both the upper Dongrong and lower Dong’anzhen formations, and the age of dinoflagellate assemblage in the upper.

Two Upper Jurassic–Lower Cretaceous palynological successions from the Qinghai-Xizang Plateau, China, are briefly introduced in this paper. The northern succession, from the Tanggula Mountains area, consists of three assemblage zones whereas the southern comprises two zones.

Upper Jurassic and Lower Cretaceous Existing Late Jurassic stratigraphy was established in when NAM and RGD published the ‘Stratigraphic Nomenclature of the Netherlands’. Van Adrichem Boogaert and Kouwe revised the standard in The palynozonation is primarily based on dinoflagellate cyst and accessory pollen.

The Cretaceous succession is divided into 15 palynozones: seven Lower Cretaceous zones and eight Upper Cretaceous. These were first formally described from the upper Albian of Kansas but have been recorded from the upper Neocomian to the Upper Cretaceous (Singh, ; Harding, ; Batten and Lister, a, b) and in the Eocene of the Mackenzie delta (G.

The lower unit ( m– m; ft– ft) consists of mudstone. The upper unit is dominated by siltstone and mudstone with minor sandstone in fining upward cycles 10–15 m thick. A carbonate bed occurs at m ( ft) and carbonate concretions possibly occur. Brideaux, WW and Fisher, MJ () Upper Jurassic-Lower Cretaceous dinoflagellate assemblages from arctic Canada.

Several studies of dinoflagellate cyst assemblages in the Upper Jurassic–Lower Cretaceous successions in Svalbard and from the western Barents Sea have been carried out over the last thirty years (Bjærke, ; Århus, ; Bailey, ; Smelror et al., ; Smelror & Dypvik, ).

evidence for the Upper Jurassic-Lower Cretaceous age of the succession cropping our along the northeastern shore of Lake Hazen (Fig. The sediments containing age diagnostic dinocysts assemblages, spores and pollen are exposed from Hazen Camp to km southeast along the Hazen Lake shore.

They were studied in three lithological sections. Craspedites canadensis in the Canadian Arctic Arch-ipelago. These assemblages are upper Tithonian in age. It would thus appear that the upper limit of G.

jurassica is probably lower Tithonian. The best exposure of the Pareodinia osming-tonesis zone, where the assemblage could be asso-ciated directly with Buchia fisheriana, was recorded. For example, the only previous records of Jurassic and Cretaceous dinoflagellate cysts from the Qinghai-Xizang (Tibet) Plateau are brief reports by Mao and Bian,Cheng and He, This study is on the dinoflagellate cysts of 14 samples from the Xiali, Suowa and Xueshan formations of the Yanshiping Group (Upper Jurassic–Lower Cretaceous) of the northern Qinghai-Xizang Plateau, China.

Dinoflagellate cyst biostratigraphy, palynofacies, depositional environment and sequence stratigraphy of the Agardhfjellet Formation (Upper Jurassic - Lower Cretaceous) in central Spitsbergen. Dinoflagellate cysts and associated aquatic palynomorphs have been recovered from the dinosaur-bearing Tendaguru Beds (Upper Jurassic–Lower Cretaceous) at Tendaguru, a hill in southeast Tanzania.

Palynofloras from these beds are generally dominated by pollen grains of Mesozoic conifers (mainly Classopollis), but dinoflagellate cysts occur.Jurassic-Lower Cretaceous lithostratigraphic nomenclature for the Danish Central Trough. Danmarks Geol. Undersøgelse, Serie A, 12, 65 pp.
