Species Globorotalia tumida Brady 1877


Discussion / Comments:
Chaisson & Leckie (1993):
Remarks: Globorotalia tumida s.s. is swollen ("tumid") at the end opposite its final chamber. Its keel is consistently heavy and often wide. The texture of the test is rough and encrusted with secondary calcite, particularly around the umbilicus. The general outline of the umbilical view of this species is consistently oblate. Similar species: Especially tumid Globorotalia menardii are common in some samples. These specimens are distinguished from G. tumida by any combination of the the following characteristics: greater symmetry of biconvexity, smoother wall texture, and/or more circular equatorial outline. G. merotumida is smaller with a smoother test wall and thinner keel. See G. plesiotumida.
