Miravetesina


Classification: Mesozoic -> Podorhabdales -> Cretarhabdaceae -> Miravetesina
Sister taxa: Speetonia, Cruciellipsis, Flabellites, Grantarhabdus, Helenea, Cretarhabdus, Retecapsa, Pickelhaube, Miravetesina,

Distinguishing features: Cretarhabdids with central area spanned by narrow axial cross and fine net.


Daughter taxa: (blue => in age window 0-800Ma)
Like M. favula but medium-sized (6-8 µm), with more pronounced axial cross, and younger age. Late Creteceous
Large (7-12 µm) cretarhabdids with central area spanned by narrow axial cross and fine net. Late Jurassic-Early Cretaceous
Specimens not identified to species level

Taxonomy:

Citation: Miravetesina Grün in Grün and Allemann, 1975
