Revised dating of the Kanjera hominids

Cranial and femoral fragments of five hominids were recovered in 1932 from exposures of Middle Pleistocene lake-beds at Kanjera on the S. shore of the Kavirondo Gulf, Kenya. L. S. B. Leakey considered that the hominids were contemporaneous with the fauna of the lake-beds, and this view seemed to be supported by results of applying the fluorine method of relative dating. Comparison of the hominids and fauna by means of radiometric assay indicates that the hominids are considerably younger.
