UNESCO registered the area of Awash Valley as a world heritage site mainly because of its immense paleo-anthropological and archaeological resources. In this regard, the Middle Awash, Hadar, Gona, Dikika, Busidima and Melka Kunture are worth mentioning.
The Awash Valley contains the oldest hominid remains that date back at least to 5million years. It also provides evidence of the genus Homo sapiens and Lithic (stone tool) technology. The major fossil remains of the area are described in the table below.
