Foraminiferal Evidence for Sediments of Santonian Age Occurring on Baratang Island, Andaman, India
Subscribe/Renew Journal
The paper incorporates systematic descriptions of ten planktonic foraminiferal species recovered from the ejected material of mud volcanoes active on the Baratang Island, Andaman. The species are Pseudotextularia browni Masters, P. carseyae (Plummer, Globotruncana aegyptiaca Nakkady, G. arca (Cushman), G. concavata (Brotzen), G. coronata (Bolli), G. fornicata Plummer, G. gansseri Bolli, G. renzi Gandolfi and G. schneegansi Sigal.
Appearance of Rugoglobigerina rugosa, Ventilabrella glabrata, Globotruncana concavata and simultaneous extinction of G. schneegansi indicate Santonian as a lower age limit of Cretaceous rocks on the Baratang Island.
