A compilation of new results on microfossils of the Quilon Formation (early Miocene, Burdigalian) at the Channa Kodi section, Kerala, southern India is presented. The stratigraphy is updated, resulting in a position within the revised planktonic foraminiferal zone M3, in calcareous nannoplankton zone CN2/NN3, and larger foraminifera zone SBZ 25. It is correlated to an astronomical age of 18.28 to 17.50 Ma. The sediment is characterized by mesophotic taxa common at 60 to 70 meters water depth, containing a large amount of additional taxa which are characteristic for seagrass meadows at 20-30 m, thus suggesting intense down slope transport processes.

Abstract
A compilation of new results on microfossils of the Quilon Formation (early Miocene, Burdigalian) at the Channa Kodi section, Kerala, southern India is presented. The stratigraphy is updated, resulting in a position within the revised planktonic foraminiferal zone M3, in calcareous nannoplankton zone CN2/NN3, and larger foraminifera zone SBZ 25. It is correlated to an astronomical age of 18.28 to 17.50 Ma. The sediment is characterized by mesophotic taxa common at 60 to 70 meters water depth, containing a large amount of additional taxa which are characteristic for seagrass meadows at 20-30 m, thus suggesting intense down slope transport processes.
