Sister taxa: Jakubowskia, Neocrepidolithus, Staurolithites, Zeugrhabdotus

Daughter taxa (time control age-window is: 0-800Ma)
Staurolithites primaevus
Small (<4 µm) elliptical muroliths with narrow bicyclic rim and narrow central area spanned by a small axial cross.
Staurolithites sp.
Specimens which cannot be assigned to any established species


Citation: Staurolithites Caratini, 1963
Rank: Genus
Type species: Staurolithites laffittei Caratini, 1963
