Today’s sketchbook:

KNM-ER 406 and KNM-ER 3733, oblique view

More little sketches. This is a famous pair. Richard Leakey and Alan Walker used KNM-ER 3733 (Homo erectus) and KNM-ER 406 (Australopithecus boisei) to illustrate the coexistence of at least two hominid species around Lake Turkana in the Early Pleistocene.
