Species Globorotalia (Globoconella) miozea Finlay 1939


Alternative name:
Diagnosis / Definition:
Kennett & Srinivasan (1983):
Test low trochospiral, biconvex, equatorial periphery lobulate, periphery sharp angled to rounded five chambers in the final whorl, increasing slowly in size; sutures on spiral side strongly curved, on umbilical side, slightly curved to radial, depressed; surface densely perforate; last two chambers smooth, rest of the test covered with tiny pustules and secondary calcite crust obscuring the pores ; aperture interiomarginal, umbilical-extraumbilical, a low narrow arch with a thickened rim.
Discussion / Comments:
Kennett & Srinivasan (1983):
Gr. (G.) miozea is distinguished from its ancestral form Gr. (G.) praescitula by its larger, more inflated test, an increase in the number of chambers in the final whorl from about four and one-half in Gr. (G.) praescitula, and more strongly developed secondary thickening and rugosity of the umbilical side.
