Description 96-98
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 retiformis—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 km 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.
