ABSTRACT
Collecting area in exposures of Middle Pliocene age, between 3.4 and 2.3 Ma, in the west-central Afar region of Ethiopia. The name derives from a large wadi named Kada Hadar by the local Afar people. Approximately 100 km2 of badland terrain underlain by the richly fossiliferous strata, defined as the Hadar Formation, have been explored and mapped since investigations of the site began in the early 1970s. The Hadar area has yielded a well-preserved and diverse mammalian fauna, including abundant remains of early hominins.
