摘要: The KNM-ER 2598 occipital is among the oldest fossils attributed to Homo erectus but questions have been raised about whether it may derive from a younger horizon. Here we report on efforts relocate locality and investigate its paleontological geological context. Although located in different East Turkana collection area (Area 13) than initially reported, stratigraphically positioned below KBS Tuff outcrops show no evidence of deflation unit, supporting an age >1.855 Ma. Newly recovered faunal material consists primarily C4 grazers, further confirmed by enamel isotope data. A hominin proximal 3rd metatarsal partial ilium were discovered <50 m reconstructed location where was originally found these cannot be associated directly with occipital. postcrania are consistent fossil represent earliest attributable erectus.
