Original description: "Pronounced petaloid periphery as in G. citae and G. petaloidea subpetaloidea; chamber subglobular, sutural elevations completely disappearing or marked sometimes by more frequent tubercles, especially along the margin of the early chambers. Ther terminal face is as usual mor or less triangular with a faint edge toward the umbilical face. The test is dextrally coiled. A fine umbilical lip appears to fringe the last chamber and extends somewhat toward the periphery."

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
