A three-member team of archaelogical experts, who discovered the paintings in a tribal habitat, said red vegetable dye had been used to draw the figures.
The paintings dating back to several centuries had faded due to the vagaries of the weather and some had been completely destroyed, they said.
Meanwhile, a square depicted the damaged picture of a man riding on an animal and of a man riding on another person's shoulders.
Yet another painting shows a person holding an axe in his hand and a dead body at his feet.
