Stone tools are globally characteristic of the Neolithic. The stone tools found at R12 consist of axes, palettes, mace-heads, grinders, and other stone objects. Although most had known usage, many of the stone objects seem to have no purpose. The stone tools were mainly made from
syenite,
sodalite,
soapstone,
sandstone, and
pumice. These materials were most likely obtained from the
Nubian Desert and a nearby igneous formation.
Axes There were 48 stone axes found from a total of 26 graves. The axes could have been used as an adze, for butchering, or as weapons. The axes at R12 are highly variable in length, width, and thickness. Because axes were found in male, female, and child graves, it is hard to tell social context of the axes.
Mace-heads There were eight mace-heads were found at R12 within a total of seven graves. They were made from granite and pumice. The mace-heads made of pumice are the first ever found in Sudan. Six of the maces had a biconical shape, one had an ovoid shape, and one was disk-shaped with rising edges around the central hole. Mace-heads usually are a symbol of power. At R12, they only found in male and child graves. This possibly means that mace-heads have a social context and may only be associated with men or children.
Stone palettes There were 50 stone palettes found at R12 within a total of 27 graves. They were usually made from sandstone or granite. The red and yellow staining on the sandstone palettes indicates that they were probably used to grind red and yellow ochre to make pigments. Peoples of R12 most likely used these pigments on themselves and animals as well as on the surface of pottery. The granite palettes were used to grind malachite and amazonite which are assumed to be used as pigments. The three different classes of stone palettes are rectangular, ellipsoidal, and irregular. Stone palettes are evenly represented in male, female, and child graves.
Grinding stones and grinders Only a few grinding stones were found at R12 within a total of six graves, both male and female. The grinding stones were made from sandstone and limestone and were ovular in shape. They are thinner, lighter, and have finer surfaces than found at Mesolithic sites in Sudan. Grinders probably served the same purpose as palettes. They are made from sandstone and occasionally pumice. The grinders were rectangular, ellipsoidal, trapezoidal, or round. The small round grinders are also found in other Neolithic settlements in Sudan. == Animal remains ==
