Species Globotruncana falsostuarti Sigal 1952


Discussion / Comments:
Caron (1985):
This species is almost a homeomorph of Giobotruncanita stuarti but differs from it in the presence of two keels on the earliest chambers, which merge in later ones into a single keel. In contrast to G. stuarti it also differs in the presence oftegilla covering the umbilical area.
