Species Rotalipora subticinensis Gandolfi 1957

Diagnosis / Definition:

Gasinski (1988):
Dimensions: D=0.28-O.SOmm, t=0.18-0.32mm

Discussion / Comments:

Caron (1985):
This species differs from R.ticinensis only in the absence of a keel on the last few chambers
Gasinski (1988):
Remarks: This species is not only of palaeobiological importance, being a form that is ancestral to R. ticinensis, but also of biostratigraphical value as a zonal marker (Robaszynski & Caron, 1979; Wonders, 1980; Caron, 1985). Nevertheless, some authors (e.g. Masters, 1977) include R. subticinensis in synonymy with R. ticinensis (Gandolfi). Local stratigraphic range: Hedbergella assemblage Zone (FAD unknown here) to the top of R. subticinensis-R. ticinensis Zone.
Pflaumann & Krasheninnikov (1977):
This species is very rare in Hole 369A: Samples 42-2, -3, CC occurring slightly before and within the range of R. ticinensis. Transitional forms between R. ticinensis and R. subticinensis are more common (Plate 6, Figure 4).
