Geological Range:
Last occurrence (top): at top of Kimmeridgian Stage (100% up, 152.1Ma, in Kimmeridgian stage). Data source: Total of range of species in this database
First occurrence (base): near base of Hettangian Stage (11% up, 201.1Ma, in Hettangian 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: Mesozoic non–coccoliths
