 The largest Sao archaeological finds have been made south of Lake Chad.Ethnic groups in the Lake Chad basin, such as the Buduma, Gamergu, Kanembu, Kotoko, and Musgum claim descent from the Sao.Lebeuf supports this connection and has traced symbolism from Sao art in works by the Guti and Tukuri subgroups of the Logone-Birni people.
