Abstract

The upper age limit of the Vindhyan Supergroup is yet a point of debate. The evidences from structural biological remains, megafossils and organic-walled microfossils, from the Bhander Group support the view that the upper age limit of the Vindhyan Supergroup does not extend beyond Vendian. This fact also gets support by the absence of Ediacaran fauna and vendotaenids in Bhander. All the evidences now point to the fact that the deposition of the Vindhyan sediments ceased before the Precambrian/Cambrian Transition interval.
