Original description: Microhedbergella Huber and Leckie, 2011:
Test wall thin, microperforate, wall pores evenly distributed and variably spaced in adult chambers, surface smooth or with scattered and weakly developed pustules. Test small to moderate in size, coiled in a very low to low trochospire, spiral side evolute, umbilical side mostly involute; chambers globular, never elongated radially, increasing rapidly to moderately in size, with 3–6 in the final whorl; aperture a low interiomarginal, umbilical-extraumbilical arch bordered by a thin lip or flap that may extend partly into umbilical region.

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
