Species Globorotalia aspensis Colom 1954


Discussion / Comments:
Bolli (1957):
The position of the apertures in the type specimens of Globigerina aspensis figured by Colom. is interiomarginal, umbilical extraumbilical. For this reason the species is here placed in Globorotalia. Colom's specimens show considerable variation in size, number of chambers in the last whorl (5-7) and shape of chambers (spherical to subangular). A similar range of varieties is found in the lower Navet of Trinidad. It appears likely that the species has developed from Globigerina soldadoensis angulosa Bolli. Detailed studies of this group in areas where more complete sections axe available might show that differences in the stratigraphic ranges of the varieties justify the erection of a number of subspecies.
