Description A well preserved, submerged assemblage of Scleractinian corals and marine molluscs was observed from a well cutting
at a depth of 8 m from the present MSL and about 8 km inland, at Vazhakala near Cochin (Kerala). Based on the
determination of age of a sample of Goniastrea retijonnis-a reef coral, it is suggested that the deposit is of Pleistocene
Era. The sea level circa 40000 y B.P. at this region was about 7-8 m than the present and the coastline extended up to 8 krn
eastward than the current. The Pleistocene coral and molluscan fauna reported herein do not display much variation from
the present faunal elements known from the seas around India. It is suggested that a regression of sea during the Late
Pleistocene resulted in the emergence of Cochin and suburbs and the physiography was subsequently modified by alluvial
deposits from the rivers.
