Abstract

Detailed examination of planktonic Foraminifera from the type section of the Miocene Kingshill Limestone and from 14 other Miocene and lower Pliocene limestone exposures in the Kingshill Seaway of St. Croix ((at 17°44' N., long 64° 46' W.; fig. 1) has led to the first publication of an in-depth biostratigraphic investigation of this area with application of the most up-to-date zonation and ecological principles. In addition, scanning electron micrographs of all identified species, subspecies, and significant paleoenvironmentally representative aberrant forms from the region have been published for the first time. Because of the importance of this work, and of the extensive diagenetic alteration of the hemipelagic deposits, as well as density of plant cover on available exposures, precise documentation of each location studied was essential. Thus, a road log was constructed (Appendix 1), in conjunction with documentary pace-and-compass readings and vertical measurements within a section to actual area of collection. Aerial plus wide-angle and normal land photographs were also taken in order to facilitate accurate relocation of all sample sites by future workers.
