Abstract
The discrepancies between the ages of the Vindhyan Supergroup (Mesoproteroz oic) determined by radiometry on one hand and by palaeontological evidence on the other are considerable. The present report of Spriggina (?) one of the important Ediacaran trace-fo ssils showing an advanced metazoan body organisation from the basal part of the Palkawan Shale Formation, Semri Group, Vindhyan Supergroup necessitate s re-establishment of the age of the these rocks vis-g-vis the advent of tr iploblastic animals on the earth.
