A collection of South Cushitic-speaking pastoralist societies (formerly called the 'Stone Bowl Culture') that spread cattle- and caprine-herding from the Horn of Africa/Sudan into the Kenyan Rift Valley and northern Tanzania during the Pastoral Neolithic. An initial Lowland phase (from roughly 5,200 years before present) in northern Kenya was followed by a Highland phase (from roughly 3,300 years before present) in the Kenya/Tanzania highlands; material culture includes distinctive carved stone bowls, pestles, cairn burials, and Nderit/Narosura pottery traditions.
Stone-bowl burial practice fades out by roughly 1,300 years before present; the population's Cushitic-speaking descendants were progressively displaced/absorbed as Nilotic and Bantu-speaking groups expanded into the region.
Continental survey with a chapter on the East African Pastoral Neolithic, including the Savanna Pastoral Neolithic / Stone Bowl tradition.
