Original description: Globigerina hoterivica Subbotina 1953: Test small, strongly convex, turret-shaped, consisting of 3 whorls; there are 4-5 highly inflated rounded chambers in the final whorl; these chambers are closely adjacent to one another so that the whole test looks like a disorganized accumulation of spherical chambers. The chambers grow very uniform in size. The sutures are short, slightly curved, almost straight. The umbilical aperture is a large slit in the extraumbilical area. The aperture has a small raised lip. Wall smooth, finely porous. Average dimensions: Diameter 0.15 mm; greatest thickness 0.10 mm.

Geological Range:
Last occurrence (top): within L. cabri zone (123.89-125.71Ma, top in Aptian stage). Data source: [copied from Chronos database]
First occurrence (base): at base of G. hoterivica zone (0% up, 141.9Ma, in Berriasian stage). Data source: zonal marker (from Timescale Creator)

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
