Geological Range:
Notes: The species W. coronata is poorly defined and so it is dificult to give it a range in the Cretaceous.
Last occurrence (top): within Danian Stage (61.61-66.04Ma, top in Danian stage). Data source: recorded occurrences in Mai et al 1997
First occurrence (base): within Late Cretaceous Epoch (66.04-100.50Ma, base in Cenomanian stage). Data source:

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: Watznaueria
