Larger foraminiferal assemblages from Oligocene platform carbonates, Jamaica: Tethyan or Caribbean?
Date of Publication
Rocks of the white limestone group of Jamaica, include, in the central part of the island, a succession of mainly miliolid grainstones (Walderston Limestone Formation), containing sparse gastropod and coral faunas of Oligocene age, part of the middle Tertiary megabank of the northern Nicaragua Rise. The associated larger foraminiferal genera, such as the archaiasinids, Peneroplis, and Praerhapidionina, together with the rare lepidocyclinids, had a tropical, cosmopolitan distribution in the Oligocene. But several important Tethyan forms such as the alveolinids, reticulate nummulitids, Austrotrillina, Cycloclypeus ,and in the lower Oligocene, Heterostegina s.l., have not been reported from Jamaica.....
