Junapani has been inhabited since 1000 BC till the present time and the megaliths of stone circles dates back to 1000 BC to 300 AD. Numerous other artefacts have also been excavated from this region which belongs to megalithic period. The iron objects found here essentially belong to 1000 BC and the local communities of various clans have helped in their identification. 150 stone circles in Junapani makes this site the second largest, among which 89 have been found in Vidharba region and 51 around Nagpur region. Out of the three circles that were initially excavated, two had unearthed human remains with funerary objects. Along with these an animal skeleton of horse family was also found.

Discoveries of Stone Circles of Junapani
The region of stone circles of Junapani has furnished various funerary antiquities. Excavations of this megalithic burial site have revealed painted red pottery among which some bear Megalithic Graffiti Symbols. Apart from this, coarse red and micaceous red wares have also been found. Elaborate studies of about 56 stone circles have been done by Archaeological Survey of India, most of which have been preserved in a good state. Cup marks have been found in about 20 circles among which 7 have marks on their sides. Some of the stone have cup marks with orthogonal sequences or parallel lines which are arranged in straight line. All the cup marks bear a definite angular range which forms 3 clusters. These marks are generally a few centimetres long and are oriented towards the sky making a definite angle with north direction. Investigations have established the probability of their stellar orientation and show changing weathers in different seasons, the time of rising and setting for specific stars and advent of monsoon season. Another interesting artefact found in one of the circles is a copper bell having an iron tongue. Piles of sticky black clay have been found in three circles. Numerous iron implements excavated have credited this site as 'iron-using'. Other antiquities are Middle Stone Age tools and stone pestles.
