Species Globigerina (Zeaglobigerina) brazieri Jenkins 1966 |
|
|
Alternative name: |
|
Diagnosis / Definition: |
Kennett & Srinivasan (1983):
Test subquadrate, low trochospiral, chambers spherical to subspherical, increasing rapidly in size as added; three to three and a half chambers in the final whorl; sutures
radial to slightly curved and depressed on both sides; surface distinctly cancellate; the pores occupy well-developed pore pits separated by interpore ridges. Umbilicus open, deep; aperture a very high arch with a thick rim, umbilical in position. |
Discussion / Comments: |
Kennett & Srinivasan (1983):
Gg. (Zg.) brazieri is distinguished from Gg. (Zg.) woodi by its subquadrate test and by the apertural placement directly opposite the suture line. Similarities in surface
ultrastructure and presence of morphologically transitional forms indicate that Gg. (Zg.) brazieri was derived from Gg. (Zg.) woodi. |
