Species Dentoglobigerina altispira Cushman & Jarvis 1936


Discussion / Comments:
Chaisson & Pearson (1997):
D. altispira also varies greatly morphologically. In Sample 154-925B-26H-5, 65-67 cm, specimens are very compressed and nearly quadrate in umbilical view, while in Sample 154-925B-25H-5, 65-67 cm, D. altispira specimens have a high trochospire and their chambers are more inflated.
Chaisson & Leckie (1993):
Remarks: This species exhibits a broad spectrum of morphologic variation that has been demarcated into subspecies by some authors (Bolli, 1957; Kennett and Srinivasan, 1983; Bolli and Saunders, 1985). Very few specimens of the Dentoglobigerina altispira globosa morphotype were observed in Hole 806B; therefore, all specimens were assigned to D. altispira (e.g., see Plate 9, Fig. 12). This taxon is characterized by its well-developed apertural teeth, appressed chambers, deep umbilicus, and moderate to high trochospire. Similar species: Early forms of D. altispira are larger than Globoquadrina cf. G. extans. In addition, D. altispira has a wider umbilicus and better developed apertural teeth.
