a, Map of Ethiopia showing the location of the Woranso-Mille site. GPTS, geomagnetic polarity time scale. b, Satellite image showing the location of the BRT area (white rectangle) relative to other nearby mid-Pliocene localities. KSD, Korsi Dora (3.6 Myr); LDD, Leado Dido’a (3.4 Myr); NFR, Nefuraytu (3.3 Myr). The black lines indicate observed fault lines. x-axis, latitude; y-axis, longitude. c, A closeup view of the BRT area showing the distribution of fossil hominins on the landscape. The squares represent the holotype and paratype specimens of A. deyiremeda. The circles represent previously and newly discovered specimens including BRT-VP-2/73 and BRT-VP-2/135 shown by the white arrows. The white line is the boundary between BRT-VP-1 and BRT-VP-2, and the black lines are the faults shown in panel b. d, Composite stratigraphical section of the BRT and WYT localities. The coloured vertical bars show the vertical extent of each locality in the section. The maximum age of the hominins from these localities is 3.55 ± 0.05 Myr based on a new 40Ar/39Ar age from K-feldspar dating of grains in a detrital sandstone (see Supplementary Information, Supplementary Fig. 1 and Supplementary Data 1 for details). The entire stratigraphical sequence exhibits normal paleomagnetic polarity, suggesting that the hominins are 3.596–3.330 Myr (chron C2An.3n). Panels b,c were modified from Google Earth (Data SIO, NOAA. U/S/ Navy, NGA, GEBCO; Image IBCAO; Image Landsat/Copernicus).
