Species Globorotalia miocenica Palmer 1945

Alternative name:

Globorotalia (Menardella) miocenica Palmer 1945

Discussion / Comments:

Bolli & Saunders (1985):
G. miocenica differs from G. pseudomiocenica in an absolutely flat spiral side. Occasionally the surface may even tend to become slightly concave. Compared with G. pseudomiocenica, the umbilical side is still higher and in equatorial view the periphery more circular and less lobate. Because the transitional forms are often erroneously identified as G. miocenica it must be stressed that correct species identification allows for little variation, one of the prime characters, being the absolutely flat spiral side. Despite its name, G. miocenica is confined to the late Early and the Middle Pliocene.
