Taxonomic discussion: Various putative Palaeozoic 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. A further 186 species were described by Bei Jing (1999 Proterozoic and Palaeozoic Coccolith Fossils in China, China Ocean Press) these are clearly diagenetic artefacts and have not been catalogued.
