Taxonomic remark IRMNG editor's note: these names, while validly published, are not presently believed to represent true Palaeozoic genera, possibly either because their assigned geologic occurrence is incorrect, or they represent non-haptophyte life forms or simply non-biota. From Nannotax3: Various putative Palaeozoic [=Cambrian through Permian] nannofossils have been described. We do not regard any of them as convincing and certainly not as evidence of ancient calcifying haptophytes. They're listed here for reference. [details]
