Species Globoturborotalita rubescens Hofker 1956

Discussion / Comments:

Chaisson & Pearson (1997):
This species is difficult to distinguish from Gt. woodi from the middle Pliocene to lower Pleistocene, where their ranges overlap. A conservative definition is adopted for Gt. rubescens and a more inclusive one for Gt. woodi. This decision is made based on the large amount of morphologic variation observed in Gt. woodi throughout its range. Specimens are called Gt. rubescens if they have a relatively smooth final chamber and a relatively loose whorl, which gives the test a more tetrahedral appearance. By contrast, the chambers of Gt. woodi tend to be more tightly embracing. In addition, the apertural lip of Gt. rubescens tends to be more distinct to even flange-like (Sample 154-925B-9H-5, 65-67 cm), and the aperture itself tends to be round (Sample 154-925B-8H-5, 65-67 cm).
