Fig. 1: Geologic context of the Lee Adoyta and Asboli regions.
From: New discoveries of Australopithecus and Homo from Ledi-Geraru, Ethiopia
a, Geologic map of the Lee Adoyta basin. Interbedded tuffs are shown as thin coloured lines. The black line indicates the position of the A–A′ cross-section shown in d. b, Stratigraphic sections at hominin localities showing the stratigraphic level of hominin fossil discoveries (yellow bones), fossiliferous horizons (white bones) and marker beds (coloured tuffs). Fossil and stratigraphic section locations are shown in a,c,d. c, Geologic map of the Asboli region superimposed on a hillshade image. Outcrops of multiple tephra deposits are shown as red lines, and these include the Giddi Sands and Lee Adoyta Tuffs that also occur in the Lee Adoyta region. d, South–north geologic cross-section of the Lee Adoyta basin showing the locations of hominin fossil sites. Vertical scale is doubled relative to the horizontal (2×VE).
