holotype: G. rugosa
holotype: G. rugosa
holotype: G. rugosa
holotype: G. rugosa
holotype: G. rugosaOriginal description: "This form develops a closely coiled test with 5 rapidly enlarging, globular chambers that are ornamented by irregularly developed rugosities or even indistinct, discontinuous, and rugulose ridges that radiate backward over each chamber from a central point on its periphery. The umbilical features of G. rugosa are precisely those that mark G. rosetta Carsey when observed in perfect and unmineralized condition."
