Broinsonia signata


Classification: Mesozoic -> Arkhangelskiales -> Arkhangelskiellaceae -> Broinsonia -> Broinsonia signata
Sister taxa: B. parca, B. enormis, B. furtiva, B. gammation, B. verecundia, B. dentata, B. cenomanica, B. ethmoquadrata, B. signata, B. galloisii, B. matalosa, B. viriosa, B. sp.,

Distinguishing features: axial cross with open quadrants


Taxonomy:

Citation: Broinsonia signata (Noël, 1969) Noël, 1970
Rank: Species
Basionym: Aspidolithus signatus Noël, 1969
Notes & discussion: This is not a very distinctive species and is possibly largely used for B. dentata type cocoliths in which the crossbars are lost due to preservation

Farinacci & Howe catalog pages: Aspidolithus signatus *

Distinguishing features: axial cross with open quadrants

Geological Range:
Last occurrence (top): within Maastrichtian Stage (66.04-72.05Ma, top in Maastrichtian stage). Data source: Burnett 1998
First occurrence (base): within Aptian Stage (112.95-126.30Ma, base in Aptian stage). Data source: Burnett 1998
