Raw material collection from type localities in Trinidad, B.W.I., where Middle Paleocene to Middle Miocene planktic foraminiferal zones were established
A collection of bulk sedimens from classical plankton foraminiferal zonal type localities, where Middle Paleocene to Middle Miocene formations are exposed in Trinidad, B.W.I. Some outcrops do not exist any more. Most of the samples were collected by John B. Saunders, but the material includes also original bulk sediments collected by investigators cited in the early stratigraphic compilation of foraminiferal zones by H.M. Bolli (1957 b, c, and d). Related collections are those from John Saunders (foraminiferal assemblages from Eocene to Miocene formations in Trinidad, B.W.I.) and the related formations in Hans G. Kugler's stratigraphic collection of Trinidad.
