Basic information
Sample name: Gombore II

Sample aka: Melka Kunture

Reference: R. Gallotti, C. Collina, J.-P. Raynal, G. Kieffer, D. Geraads, and M. Piperno. 2010. The early Middle Pleistocene site of Gombore II (Melka Kunture, Upper Awash, Ethiopia) and the issue of Acheulean bifacial shaping strategies. African Archaeological Review 27:291-322 [ER 3861]
Geography
Country: Ethiopia



Coordinate: 8.704733° N, 38.601631° E
Coordinate basis: stated in text

Time interval: Early Pleistocene

Max Ma: 0.875

Min Ma: 0.709

Age basis: Ar-Ar

Geography comments: based on Fig. 1, the coordinate given by Altamura et al. (2018) for "the area of Melka Kunture" applies to the Gombore cluster of sites and possibly to Gombore II itself, so it is used here
the site "dates to circa the Brunhes Matuyama Reversal" and Altamura et al. (2018) state that it lies between "volcanic sediments dated by 40Ar/39Ar to 0.875 ± 0.010 Ma and 0.709 ± 0.013 Ma, respectively"

Environment
Lithology: siliciclastic (mixed)

Taphonomic context: fluvial deposit

Archaeology: stone tools

Habitat comments: six stratigraphic levels within the lower local unit are described, of which the "0.10 m thick" unit CPB yielded artefacts and fossils; it is a "Clast-supported thin pebble bed" with a "sandy matrix" that represents a fluvial channel
however, some fossils were recovered from the upper local unit at the hippopotamus "Butchering Site" within the larger locality
there are 1753 lithic artefacts in total

Methods
Life forms: carnivores,primates,rodents,ungulates,birds

Sampling methods: quarry

Sample size: 421 specimens

Years: 1966 - 1975, 1992 - 1995, 2001

Sampling comments: there are multiple sublocalities excavated in different years, including the Open Air Museum excavated in 2001, but a faunal list is only given for the entire site and all excavations
Altamura et al. (2018) refer the "Homo erectus" material to Homo heidelbergensis
