Several paleoenvironmental analyses of East African hominid lo- calities were presented. Hideo Nakaya (Kagawa University, Japan), Gen Suwa (University of Tokyo, Japan), and Berhane Asfaw (Rift Valley Re- serve, Ethiopia) presented data on the large mammalian fauna from Konso, Ethiopia, where specimens of Homo erectus and Australopithecus boisei have been found.1 The Konso strati- graphic formation was divided into six successive faunal zones, of which Zones 4 and 5 (1.45 to 1.35 Ma) were hominid-bearing. Analysis showed a transition from open grassland to mixed grassland and woodland, as in- dicated by decreasing proportions of alcephalines and increasing numbers of bovids, tragelaphines, and equids. The fauna of Konso is more similar to the Olduvai Bed II assemblage than to the geographically closer Turkana ba- sin, which possibly can be explained by the similarities in altitude between Figure 1.
