Rucinolithus magnus


Classification: Mesozoic -> Nannoliths inc sedis -> Nannoliths inc sed - radiate multielement -> Rucinolithus -> Rucinolithus magnus
Sister taxa: R. hayi, R. magnus, R. oriens, R. wisei, R. pinnatus, R. sumastrocyclus, R. windleyae, R. sp.,

Distinguishing features: 6, long, tapering rays - and nannolith large


Taxonomy:

Citation: Rucinolithus magnus Bukry, 1975
Rank: Species
Notes & discussion: Varol & Houghton (1996) suggest this is an ascidian spicule, however the c-axis orientation of the ray orientiation is tangential in at least some specimens (see Calcite Palace specimen).
