A survey of Ethiopia's Middle Awash Valley in 1981 yielded new and significant archaeological, palaeontological, geological and geochronological results. Included in the new discoveries are hominid fossils from the Pliocene which show primitive cranial anatomy and a femur adapted to bipedality. Archaeological records document human technological change spanning the past 1.5 Myr. 
Ecological and temporal placement of early Pliocene hominids at Aramis, Ethiopia
TLDR
Radioisotopic dating, geochem-ical analysis of interbedded volcanic ashes and biochronological considerations place the hominid-bearing deposits in the Middle Awash research area of Ethiopia's Afar depression at around 4.4 million years of age.
African Homo erectus: old radiometric ages and young Oldowan assemblages in the Middle Awash Valley, Ethiopia.
TLDR
Fossils and artifacts recovered from the middle Awash Valley of Ethiopia's Afar depression sample the Middle Pleistocene transition from Homo erectus to Homo sapiens, supporting the hypothesis that Middle Pleistsocene Oldowan assemblages represent a behavioral facies of the Acheulean industrial complex.
The Early Stone Age lithic assemblages of Gadeb (Ethiopia) and the Developed Oldowan/early Acheulean in East Africa.
The Early Stone Age sites of Gadeb (Ethiopian South-East Plateau) were excavated under the direction of Desmond Clark in the 1970s. Dated to between 1.45 and 0.7 Ma, Gadeb proved that humans had
Geochronology, stratigraphy and geochemistry of Cindery Tuff in Pliocene hominid-bearing sediments of the Middle Awash, Ethiopia
TLDR
Cindery Tuff is a subalkaline, rhyolitic air-fall deposit that was probably produced by a mixed-magma eruption, and its age is estimated to be 3.8–4.0 Myr, which implies that associated hominid skull fragments are at least 3.9 Myr old.

Summary Along the western margin of the Afar depression there is a fluvio-lacustrine sequence, well known for its hominid fossils, which consists of a 150–300 m thick layer of coarse to fine detrital
Early hominid from Baringo, Kenya
Palaeontological evidence and comparative molecular studies of modern hominoids suggest that major evolutionary changes occurred in the African Hominoidea between 14 Myr and 4 Myr1–3. Unfortunately,
Mio-Pliocene mammals from the Middle Awash, Ethiopia
Abstract The Middle Awash paleontological study area, located in the Afar Rift of Ethiopia, has yielded fossils spanning the last six million years. The geology and geochronology of the Mio-Pliocene
Integrative geochronology calibrates the Middle and Late Stone Ages of Ethiopia’s Afar Rift
TLDR
How chronological control can be obtained in tectonically active and stratigraphically complex settings to precisely calibrate crucial evidence of technological, environmental, and evolutionary changes during the African Middle and Late Pleistocene is demonstrated.
The Belohdelie frontal: new evidence of early hominid cranial morphology from the Afar of Ethiopia
TLDR
Results of this study support the phylogenetic hypothesis put forward by many workers that A. afarensis gave rise to the “robust” Australopithecus and A.africanus clades.
Cenozoic Climatic Changes in Deserts: A Synthesis
Deserts are excellent geological, geomorphic, and archaeological museums. The very aridity to which they owe their existence has made them remarkable repositories of past depositional and erosional

TLDR

Hominid occupation of the East-Central Highlands of Ethiopia in the Plio–Pleistocene
Stone artefacts and fossil evidence suggest that hominids did not reach the high plateau of Ethiopia until ∼1.5 Myr ago. Contact between hominids of the plateau and the Rift Valley seems likely.
