survey in the 1970's of the Gona sediments discovered them to contain late Pliocene
archaeological sites. Initially estimated to be ca. 2.5myo, it was not until the
research of Dr. Sileshi Semaw and colleagues provided reliable dates (2.52-2.60mya) for
these materials, thus verifying the Kada Gona D'ar valley as having the earliest evidence
of stone tool manufacture and use.
The international, multidisciplinary Gona Paleoanthropological project began field research in earnest in 1999. To date, well over 100 paleontological and archaeological sites have been found ranging in age from latest Miocene to the middle Pleistocene. This period spans the earliest stages of the human lineage from Ardipithecus ramidus through late Homo erectus. This period also recorded the major technological innovations especially the adoption of stone tools as well as the transition to and evolution of the Acheulian stone tool tradition. Overall, these archaeologically and faunally rich deposits have much to tell us about the biological and behavioral evolution of our ancestors during the past 5 million years.
