Lithostromation martinii


Classification: ntax_cenozoic -> Nannolith families inc sed -> Lithostromationaceae -> Lithostromation -> Lithostromation martinii
Sister taxa: L. hohnensis, L. pyramidale, T. tripartitus ⟩⟨ L. martinii, L. nodosum, L. obscurum, L. reginum ⟩⟨ L. operosum, L. perdurum, L. simplex, L. biconvexitas, L. sp.

Taxonomy:

Citation: Lithostromation martinii (Best & Müller 1972) Young 2023
Taxonomic rank: species
Basionym: Trochoaster martinii Best & Müller 1972
Taxonomic discussion: This seems to be a discrete form but clearly related to the other Lithostromation species, so it was recombined in Lithostromation by Young 2023

Distinguishing features:
Parent taxon (Lithostromation): Triangular to stellate nannoliths with porous structure formed from small crystallites. All show 3-fold symetry but with a wide range of forms.
This taxon: Hexaradiate with distinct free rays, all 6 rays similar,  ridge runs along length of rays

Farinacci & Howe catalog pages: T. martinii *

It looks like Actiniscus pentasterias (Ehrenberg) Ehrenberg.

Indeed Actiniscus and Trochoaster can look really similar in SEM - but of course in LM there is no problem to separate them, as Actiniscids are siliceous
