Nannotax3 - ntax_cenozoic - Cruciplacolithus filigranus

Citation: Cruciplacolithus filigranus Mai, 2001

Synonyms:

Catostaura filigrana (Mai 2001) Aubry in Aubry & Bord (2009). The genus Catostaura was proposed for this species on the basis of its unusual central structure and the way in which lower tube cycle protrudes distally.

Distinguishing features: Cruciplacolithus with narrow cross bars and a delicate net.

Geological Range:
Last occurrence (top): within NP15 zone (42.87-46.29Ma, top in Lutetian stage). Data source: Bown, 2010
First occurrence (base): within NP1 zone (65.47-66.04Ma, base in Danian stage). Data source: Bown, 2010
