Abstract

Abstract. Beautifully preserved dinoflagellate cysts continue to be discovered in UK Cretaceous chalks and provide important new biostratigraphic information. Five new species – Conosphaeridium norfolkense sp. nov., Glaphyrocysta coniacia sp. nov., Impletosphaeridium banterwickense sp. nov., Sentusidinium devonense sp. nov., Sentusidinium spinosum sp. nov. and the new subspecies Spiniferites ramosus subsp. ginakrogiae subsp. nov. – are described from Upper Cretaceous strata of the British Geological Survey (BGS) Banterwick Barn and Trunch boreholes (onshore UK). An emended diagnosis for Odontochitina diducta Pearce is also provided to broaden the morphological variability in the type material.

英国Chalk两个陆上钻孔中的其他新的有机壁甲藻囊肿

摘要在英国白垩纪白垩系中继续发现保存完好的甲藻囊肿，并提供了重要的新生物地层学信息。五个新种——北福氏锥藻（Conphosphaeridium norfolkense sp.nov.）、分生球藻（Glaphyrocysta conacia sp.nov..）、矮柄隐球藻（Impletosphaerium banterwickense sp.nov.），devonense sp.nov.Sentusidinium spinosum sp.nov.nov.和新亚种Spiniferites ramosus subsp。银杏亚种。nov.–来自英国地质调查局（BGS）BanterwickBarn和Trunch钻孔（英国陆上）的上白垩纪地层。还提供了对双导管Odontochitina didurce Pearce的校正诊断，以拓宽类型材料的形态学变异性。

期刊介绍： The Journal of Micropalaeontology (JM) is an established international journal covering all aspects of microfossils and their application to both applied studies and basic research. In particular we welcome submissions relating to microfossils and their application to palaeoceanography, palaeoclimatology, palaeobiology, evolution, taxonomy, environmental change and molecular phylogeny.
