Ethno archaeological evidences and studies very often facilitate the interpretation of significance of rock art. But sometimes there are problems in explaining the things if there is discrepancy between local ethnic activities and the rock art of by-gone days which may be due to either a remarkable shift in social behaviors during long period span or to the relative seclusion of the developing society from art traditions manifested in local rock art. The present paper is based on the ethno rock art investigation made in the Kaimur region of Bihar. In this paper the author has attempted to link between ancient rock art living pattern and the art and culture of modern local group especially the tribe and semi tribes residing in the hill, foot hill and the plain.
