This taxon: Nannolith genera without clear affinities to any other genera

Morphology:

Geological Range:
Last occurrence (top): at top of Maastrichtian Stage (100% up, 66Ma, in Danian stage). Data source: Total of range of species in this database
First occurrence (base): in upper part of Sinemurian Stage (68% up, 193.5Ma, in Sinemurian stage). Data source: Total of range 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
• Neptune data: this is a higher taxon page so Neptune data is not plotted. For the customisable plot option go to a genus page Parent: Nannoliths inc sedis
