Geography
Country: Eritrea
Coordinate: 14.72° N, 39.93° E
Coordinate basis: estimated from map
Formation: Alat
Time interval: Early Pleistocene
Max Ma: 1.07
Min Ma: 0.98

Geography comments: "south of Wadi Dandiero, north of Wadi Baebele" (coordinate estimated based on Fig. 3 in Abbate et al. 2004)
Abbate et al. (2004) indicate that most of the Buia material is from the Alat Formation, which is bounded by 1.07 and 0.98 Ma by Albianelli and Napoleone (2004) based on magnetostratigraphy and cyclostratigraphy

cut marks on some specimens are described by Fiore et al. (2004), who do not specify an accumulation agent
