Taxonomy:

Citation: Staurolithites primaevus Bown, 2005

Rank: Species

Taxonomic discussion: Similar to Mesozoic Staurolithites species but the only Cenozoic representative currently recognised: characterized by small size and compact morphology.

Distinguishing features: Small (<4 µm) elliptical muroliths with narrow bicyclic rim and narrow central area spanned by a small axial cross.

Geological Range:
Last occurrence (top): within NP11 zone (53.70-54.17Ma, top in Ypresian stage). Data source: Bown, 2005
First occurrence (base): within NP5 zone (59.54-61.51Ma, base in Selandian stage). Data source: [PRB rough estimate]

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: Staurolithites
