Microrhabdulus belgicus


Classification: ntax_mesozoic -> Nannoliths inc sedis -> Microrhabdulaceae -> Microrhabdulus -> Microrhabdulus belgicus
Sister taxa: M. belgicus, M. decoratus, M. helicoideus, M. undosus, M. sp.

Distinguishing features:
Parent taxon (Microrhabdulus): Rod-shaped nannoliths with (sub)circular cross-section and complex construction from systematically arranged laths, commonly creating a "chequered" LM image.
This taxon: Microrhabdulus tapering toward both ends and with rings of nodes.


Taxonomy:

Citation: Microrhabdulus belgicus Hay & Towe, 1963
Rank: Species
Synonyms:
Taxonomic discussion: Rather remarkably this taxon was described three times in 1963, reflecting the extensive interest in Cretaceous nannofossil taxonomy at that time.
