While dealing with archaeology particulary during excavation animal bones play a vital role in indicating the environmental, climatic conditions, food habits etc. Through I have excavated many archaeological sites right from Prehistoric to Historic time, I thought it proper to write about these, so that students and scholars could be benefitted in knowing the climatic conditions, food habit and aggressiveness of the society those days. Animals are good friends of man but became aggressive when disturbed as is the case with elephant in Chhattisgarh nowadays. Let them live in their habitat and they we be peaceful.
