Taxonomy

Citation: Globotruncana mariei Banner and Blow 1960
Rank: Species
Basionym: Globotruncana mariei
Taxonomic discussion: Globotruncana cretacea Cushman, 1938 was the original designation for this species, but Banner and Blow (1960) designated G. mariei as the new name for the original Cushman holotype after they reassigned Globigerina cretacea dOrbigny 1848 (=Archaeoglobigerina cretacea) to Globotruncana. [copied from Chronos database]

Original description: "This species differs from G. arca in the fewer chambers in the whorl, flatter dorsal side, typically more convex ventral side, more definitely oblique sides to the chambers on the ventral side, and differently shaped chambers."

Plot of occurrence data:

Dec 2017 - Plotting of Neptune data has been re-enabled on the Mesozoic pages following revision of the age-models in Neptune. The data is, however, still very sparse for the Early Cretaceous

  • Histogram - Neptune occurrence data from DSDP and ODP proceedings. Pale shading <50 samples in time bin. Interpret with caution & read these notes
  • Note to users in China - the diagram may not plot unless you use a VPN since I use google services on the website. If this is a problem please contact me 谢谢.
