| Summary: | Manumiella seelandica (Lange 1969) Bujak and Davies 1983, emend. Firth 1987 occurs in great abundance, together with a closely related and possibly conspecific form, Isabelidinium? sp., virtually at the end of the Maastrichtian. The abundance of M. seelandica immediately adjacent the Cretaceous/Paleogene (KPg) boundary, and its global distribution, serve as an excellent biostratigraphic marker for dating it. The abundance spike is widely distributed in both Northern and Southern hemispheres, and ranges from locations as far south as Seymour Island, Antarctica to as far north asWest Greenland. The global distribution of the M. seelandica spike in such widely separated areas, and the ease with which it is recognized in closely sampled sections, underscores its value in dating. Until recently, this short-lived event was correlated within an interval of global sea level fall and regression which extended from the latest Maastrichtian into the earliest Danian; that is, that the species became numerically abundant ... : Supplement to: Habib, Daniel; Saeedi, Farnosh (2007): The Manumiella seelandica global spike: Cooling during regression at the close of the Maastrichtian.
