Detailed stratigraphic analysis of the Omo I and Omo II fossil localities confirms both the relational and sequential context reported by Butzer in 1969. The two fossils derive from approximately the same level within upper Member I of the Kibish Formation. Additional features of the local stratigraphic sequences indicate a complex history of depositional events, minor erosional surfaces, and weak soil formation throughout upper Member I.
对奥莫I和奥莫II化石地点进行的详细地层分析证实了布策于1969年报告的相关和先后顺序背景。这两块化石来自基比什组上段I的大致同一层位。当地地层序列的其他特征表明，在上段I中存在沉积事件、轻微侵蚀面和微弱土壤形成的复杂历史。
