Citation: Staurolithites ellipticus (Gartner, 1968) Lambert, 1987
Rank: Species
Basionym: Vekshinella elliptica Gartner, 1968
Synonyms:

Farinacci & Howe catalog pages: Vekshinella elliptica *

Distinguishing features: Bicyclic with thick cross-bars which flare toward the centre, where they suport the base of a hollow spine.


Morphology remarks: "Characterised by its compact form, obviously bicyclic wall and relatively thick cross-bars. The cross-bars flare towards their central juncture, where they support the base of a hollow spine. This species is conspicuous in the Upper Aptian and Albian." [Rutledge 1994]
