Bodo D'ar
Basic information
Sample name: Bodo D'ar
Reference: J. E. Kalb, C. B. Wood, C. Smart, E. B. Oswald, A. Mabrete, S. Tebedge, and P. Whitehead. 1980. Preliminary geology and palaeontology of the Bodo D'ar hominid site, Afar, Ethiopia. Palaeogeography, Palaeoclimatology, Palaeoecology 30:107-120 [ER 3840]
Geography
Country: Ethiopia
Coordinate: 10° 37' 30" N, 40° 32' 30" E
Coordinate basis: stated in text
Time interval: Middle Pleistocene
Max Ma: 0.64
Age basis: Ar-Ar
Geography comments: "on the east side of the Awash River"
within the Upper Bodo beds
thought to be Middle Pleistocene based on faunal composition and artefacts
an average of multiple Ar/Ar dates on a vitric tephra from unit u1 in the Bodo section, below the fossil-yielding unit u-t yielded an average of 0.64 +/- 0.04 Ma (Clark et al. 1994)

Environment
Lithology: siliciclastic (mixed)
Taphonomic context: fluvial deposit
Archaeology: stone tools
Habitat comments: "concentrations of fossils and Achedulian artefacts are exposed in the banks of both" surrounding streams
there are three layers in the local succession: a conglomerate with "Abundant fossil bone and artefacts", a medium sand with "abundant" fossils including the Homo skull, and "medium to fine sand and silty sand" with "very few fossils"
the fauna is considered homogeneous, so it is listed all together

Years: 1976
Sampling comments: some fossils were recovered before 1976
there are two test pits, but most of the material is apparently from extensive surface collections
