Holocene planktonic foraminifera from the shelf sediments off Kerala Coast

Abstract

Twenty-two planktonic foraminifers were identified from a few samples collected aboard INS KISTNA at 9~'N and 76~'E, at 89 metres depth from the bottom sediment-water interface. A few of the more characteristic features of each are described. Some of the species have a geologic range from Miocene to late Pleistocene and Recent also. @iGlobigerina hexagona@@ and @iGloboquadrina conglomerata@@ which disappeared from the Atlantic earlier (50,000 to one million years ago) are seen to be living today in the Indian Ocean. A few species are rare and restricted forms
