Variant: Unidentifiable nannofossil is regarded here as a variant of Crystals and crud. I.e. It is a subjective junior synonym, but some workers many find it useful for some studies (e.g. experienced biostratigraphers working with abundant, well preserved material), but for most purposes differentiating it is not reccomended.

Taxonomic discussion: This category is given here to allow comprehensive databasing of described nannofossils. It is needed because in the older literature some nannofossils were validly described and are included in e.g. the Farinacci catalog but it is not possible to tell what was described due to inadequacies in the illustrations and/or diagnosis. It also is useful to identify which taxa might usefully be identified as unsuitable for defining species from in the future. NB Listing in progress, does not include numerous Kamptner species, which will be listed separately
Distinguishing features: Parent taxon (Crystals and crud): This taxon: Validly described nannofossil species which cannot be assigned to a known species due to poor preservation and/or illustration of the holotype
The morphological data given here can be used on the advanced search page. See also these notes
Geological Range: Last occurrence (top): at top of (100% up, 0Ma, in "Holocene" stage). Data source: Total of ranges of the species in this database First occurrence (base): within (-Ma, base in "Holocene" stage). Data source: Total of ranges of species in this database
Plot of occurrence data:
Range-bar - range as quoted above, pink interval top occurs in, green interval base occurs in.
Triangles indicate an event for which a precise placement has been suggested
(NB There is no histogram as there are no occurrence records for the taxon in the Neptune database) Parent: Crystals and crud
