Diagnosis and comparison: The most striking features of Globorotalia petaliformis n. sp. are the very lobate peripheral outline and the often step-like sutures on the spiral side which give an imbricate appearance. Because of these characteristics, the test of this species resembles a flower; hence the name petaliformis (petalled).
It is a very variable species, especially concerning its biconvexity, the character of the sutures, the kind of angularity of the peripheral margin, and its imbricate appearance. However, it is a very peculiar and easily identifiable foraminifer which is not closely related to any Globorotalia as yet described. Some tests of Globorotalia petaliformis n. sp., because of the imbricate appearance, resemble the Recent cold-water species Globorotalia cavernula Bé.
Observations: I prefer to establish it as a new taxon and not to put it in open nomenclature because it is a very peculiar, typical, and easily identifiable species which, in addition, has a relatively short stratigraphic range. In spite of all my efforts to find at least a related species, I was not able to find any.
