Abstract

Two radiolanan assemblages are distinguished in the Calocydetta (C) costata Zone of Early to Middle Miocene from a stratigraphic section of Inghs Island, Andaman Sea Fluctuations in percent abundance of cooler and warmer water taxa in the section indicate changing water mass conditions Water mass fluctuations in the form of cooling and warming of surface water have also been identified in the same stratigraphic interval from various tropical Indian Ocean DSDP and ODP sites by other investigators using oxygen isotope data.
