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

Age basis: paleomag

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

Environment
Lithology: siliciclastic (mixed)

Taphonomic context: lake deposit

Habitat comments: the Alat Formation is deltaic and lacustrine and includes "silts, clays, thin calcareous beds, and ash layers" plus "sandy bodies" higher in the section (Abbate et al. 2004)
cut marks on some specimens are described by Fiore et al. (2004), who do not specify an accumulation agent

Methods

Sample size: 109 specimens

Years: 1995 - 1997, 2000
