Dinoflagellate Cyst Taxonomy and Biostratigraphy of the Eocene Bracklesham Group in Southern England

Micropalaeontological dating of the Prémontré mammal fauna (MP10, Prémontré Sands, EECO, early late Ypresian, Paris Basin)

“…Areoligera sentosa, Impletosphaeridium cracens, Phthanoperidinium comatum, Enneadocysta arcuata and Areoligera tauloma constitute a chronological sequence of appearances within the upper Ypresian (upper NP12 -upper NP 13), with A. tauloma as youngest member. A more or less similar sequence of events has been identified at Whitecliff Bay (Eaton, 1976), Alum Bay (Eaton, 1976) and Bracklesham Bay (Islam, 1983) in S. England, and in the Wursterheide borehole in NW Germany (Heilmann-Clausen & Costa, 1989), although not the entire suite and often with striking differences. At Whitecliff Bay and Alum Bay I. cracens and P. comatum appear simultaneously in the stratigraphic record, whereas at Bracklesham Bay, the first occurrence of P. comatum predates the first occurrence of I. cracens.…”

“…Köthe's refined dinoflagellate cyst zonation, covering the eastern North Sea Basin, cannot be applied here because of the poor preservation and the moderate diversity of the assemblages, resulting in the absence of Köthe's subzonal markers. Correlation of the Prémontré Sands with the upper part of the Wittering Formation in southern England is based on the co-occurrence of A. diktyoplokum and I. cracens, and the absence of A. tauloma, referring to the lower part of the Phthanoperidinium comatum Assemblage Zone (B-3), as defined in Bujak et al (1980) (see also Islam, 1983). However, this zonal attribution is not in line with the data recorded in the Belgian Basin (Steurbaut & Van Simaeys, unpublished information; see discussion below).…”

Organic-walled dinoflagellate cyst biostratigraphy of the Well Höflein 6 in the Cretaceous–Paleogene Rhenodanubian Flysch Zone (Vienna Basin, Austria)

“…Williams & Bujak (1985) documented that Apectodinium homomorphum ranges from the Upper Paleocene to the Middle Eocene. Diphyes ficusoides is recorded in the Lower Eocene in Virginia (Edwards 1989), Lower to Middle Eocene in Germany (Heilmann-Clausen & Costa 1989;Köthe & Piesker 2007) and in southern England (Islam 1983), and ranges from the Middle to the Upper Eocene according to Stover et al (1996). Deflandrea phosphoritica is recorded in the Lower Eocene in Germany ( (Gerlach, 1961) Artzner & Dörhöfer, 1978emend.…”
