Question: What was found, in the Cango Valley along with Circular stone hearths and calcified dung remains of domesticated sheep, that is a cutting tool shaped somewhat like an axe that dates back to the stone age?

<P0-S0> The adze ( ; alternative spelling: adz) is a cutting tool shaped somewhat like an axe that dates back to the stone age. <P0-S1>  It can be any tool with a sharp cutting edge. <P0-S2>  Adzes are used for smoothing or carving wood in hand woodworking, similar to an axe but with the cutting edge perpendicular to the handle. <P0-S3>  Two basic forms of an adze are the hand adze, a short handled tool swung with one hand, and a foot adze, a long handled tool capable of powerful swings using both hands, the cutting edge usually striking at foot or shin level. <P0-S4>  The blade of an adze is set at right angles to the tool's shaft (like a hoe or plane), in contrast to an axe's blade, which is in plane with the shaft. <P0-S5>  A similar, but blunt, tool used for digging in hard ground is called a mattock. <SEP> <P1-S0> In archeology, lithic technology refers to a broad array of techniques and styles to produce usable tools from various types of stone. <P1-S1>  The earliest stone tools were recovered from modern Ethiopia and were dated to between two-million and three-million years old. <P1-S2>  The archaeological record of lithic technology is divided into three major time periods: the Paleolithic (Old Stone Age), Mesolithic (Middle Stone Age), and Neolithic (New Stone Age). <P1-S3>  Not all cultures in all parts of the world exhibit the same pattern of lithic technological development, and stone tool technology continues to be used to this day, but these three time periods represent the span of the archaeological record when lithic technology was paramount. <P1-S4>  By analysing modern stone tool usage within an ethnoarchaeological context insight into the breadth of factors influencing lithic technologies in general may be studied. <P1-S5>  See: Stone tool. <P1-S6>  For example, for the Gamo of Southern Ethiopia, political, environmental, and social factors influence the patterns of technology variation in different subgroups of the Gamo culture; through understanding the relationship between these different factors in a modern context, archaeologists can better understand the ways that these factors could have shaped the technological variation that is present in the archaeological record. <SEP> <P2-S0> Ovis longipes palaeo-aegyptiacus is a type of the extinct wild barbary sheep found in the ancient Southern Egypt and Nubia. <P2-S1>  The ovacaprines were domesticated and often depicted on the stone tomb murals of the pharaohs for religious or aesthetic purposes. <P2-S2>  "Ovis longipes palaeo-aegyptiacus" was one of the two most commonly domesticated sheep utilized on the reliefs of early pharaonic tombs mostly because of its unique loosely spiraling horns which came out of the sides of the skull. <P2-S3>  A similar form of the sheep called "Ovis platyura aegyptiaca" had horns that developed downward and curled forward. <SEP> <P3-S0> Boomplaas Cave is located in the Cango Valley in the foothills of the Swartberg mountain range, north of Oudtshoorn, Eden District Municipality in the Western Cape Province, South Africa. <P3-S1>  It has a 5 m deep stratified archaeological sequence of human presence, occupation and hunter-gatherer/herder acculturation dating back 80,000 years. <P3-S2>  The site's documentation contributed to the reconstruction of palaeo-environments in the context of changes in climate within periods of the Late Pleistocene (12,000 - 80,000 years BP) and the Holocene (since 12,000 years BP). <P3-S3>  The cave has served multiple functions during its occupation, such as a kraal (enclosure) for animals, a place for the storage of oil rich fruits and as a hunting camp. <P3-S4>  Circular stone hearths and calcified dung remains of domesticated sheep as well as stone adzes and pottery art (painted stones) were excavated indicating that humans lived at the site and kept animals.
