Fetchamium prolixispinosum gen. et comb. nov. (division Dinoflagellata)
Abstract. Oligosphaeridium is a gonyaulacacean dinocyst lacking cingular processes and possessing a
distinctive process centred on the antapical plate indicating a sexiform
hyposomal tabulation. However, specimens referable to the description of
Oligosphaeridium prolixispinosum Davey and Williams, 1966, although lacking cingular processes, are clearly
not sexiform. As an additional complication, the holotype of
Oligosphaeridium prolixispinosum possesses cingular processes. In this brief contribution, we describe the
new genus Fetchamium to accommodate the new transfer Fetchamium prolixispinosum gen. et comb. nov. and provide a
discussion and emended diagnosis of the species.
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.
