Species Globorotalia ungulata Bermudez 1960


Alternative name:
Globorotalia (Globorotalia) ungulata Bermudez 1960
Discussion / Comments:
Bolli & Saunders (1985):
With few exceptions (Stainforth et al., 1975) the species has been recorded only from the Holocene. Because of its tumid, somewhat elongate test it was considered to be related to G. tumida. However, the test, including the peripheral keel, is much more delicately built. specimens when present are as a rule considerably less frequent than G. tumida.
Chaisson & Leckie (1993):
Similar species: The smooth finely perforate texture distinguishes this species from Globorotalia tumida, which is always a rough textured species. In Hole 806B, unusually deep records of G. ungulata cause its range to overlap with that of G. plesiotumida, with which it shares an oblong form and a final chamber that, on the spiral side, is longer radially than it is wide. Both species are also more inflated on the umbilical side, and the most reliable way to separate them is by the smooth glassy texture and higher dorsal spire of G. ungulata.
