The cave contained the remains of buried fruits from nearby rainforest trees; mussel shells and fish bones from the river; drops of the red pigment used to make the paintings on the cave walls; and, in the same layer of deposit, stone projectile points buried near the mouth of the cave.Apparently the cave was occupied several times a year by people who camped in the main cavern, cooked meals, knapped stone spear points, and made paintings, including what may be calendrical or astronomical calculations.In ancient times, sources of clays were widely available, between them soils or surface sediments have been the proper sources for ceramics without further treatment, due to their natural mixture of plastic and nonplastic components [1].Ceramics is an inorganic nonmetallic material obtained through thermal processing of natural raw materials at relatively high temperature [2]. “Enhancing ethno-pedology: integrated approaches to Kanuri and Shuwa Arab definitions in the Kala-Balge region, northeast Nigeria.” Catena 58: 41-64. “Interactions between the Greenland Ice Sheet and the Liverpool Land coastal ice cap during the last two glaciation cycles.” Journal of Quaternary Science 20: 269-283.
