Taxonomy

Citation: Dicarinella hagni (Scheibnerova, 1962)
Rank: Species
Basionym: Praeglobotruncana hagni

Type images:

Original description: Test of medium size, biconvex, with umbilical side more convex than spiral one. The periphery with two quite closely spaced keels. The chambers of both sides slightly inflated. The last chamber more inflated than the others. In the last whorl 6-8 chambers. Chambers of the umbilical side covered by tubercles, the spiral side smooth. Umbilicus deep, narrow. The aperture interiomarginal; the accessory apertures not observed. Sutures radial, depressed.

Entries in the Catalog of original descriptions: Praeglobotruncana hagni

Geological Range:
Last occurrence (top): within D. concavata zone (86.71-89.91Ma, top in Coniacian stage). Data source: [copied from Chronos database]
First occurrence (base): within H. helvetica zone (92.56-93.52Ma, base in Turonian stage). Data source: [copied from Chronos database]

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
