Figure 3. Mean stat-tracks for hominin tracks at Laetoli.

The trackmaker is generally accepted to have been Australopithecus afarensis. (A) G1 trackway. (B) G3 trackway. (C) L8 trackway. (D) M9 trackway. (E) TP2 trackway. (A–E) are all illustrated at the same scale. (F) Mean stat-track of Laetoli tracks, which could be used as mediotype in a future revision of Praehominipes laetoliensis. (G) Comparison between the Laetoli mediotype (red) and a modern human track (black). Note that the comparison is scale-free. See Table 1 for more information of the specimens.
