Original description: "Form more convex on the dorsal side than Globotruncana contusa subsp. Scutilla Gandolfi, 1955, the convexity being more pronounced in the last stages; last chambers higher, petaloid and often undulated; sutural elevations thinner and frequently split on the dorsal side into the lines of beads. The form is double-keeled, becoming often single-keeled in the more adult stages. The umbilical cavity is large, the umbilical lips are thin and slightly more arched than in Globotruncana contusa scutilla and Globo truncana contusa subsp. Contusa (Cushman)."

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
