Extended Data Fig. 6: Modelling of all 22 sites to establish the timing of the Extinction Window.

The master Bayesian plot composed of the modelled age ranges for all 22 caves. The names of the caves have been included on the left ā colour coded to signify the G. blacki-bearing caves (green) and the non-G. blacki-bearing caves (brown). Following each cave name its ___location is signified in brackets with either CZ ā Chongzuo area or BB ā Bubing Basin. See Fig. 1 for the locations of these areas. The master model has been presented at 2 Ļ error margin with the age range of each cave representing the upper and lower boundary of the fossil-bearing layer. The extinction window of G. blacki lies in the boundary between Shuangtan and Gongjisgan Caves (red horizontal line) and has been modelled between 295ā215,000āyrs ago (255ā+āā 40 ka) (red vertical line).
