The discovery of three late Middle Pleistocene hominid crania, Homo sapiens idaltu, at Herto in the Middle Awash research area in Ethiopia in 1997 shed considerable light on this little-known period in Africa. These fossils consist of two adults' and a child's crania. All are morphologically intermediate between geologically earlier African fossils and anatomically modern later Pleistocene humans. The three Herto Homo sapiens idaltu crania show cutmarks indicating defleshing using sharp-edged stone tools. The post-mortem modifications and manipulation of the crania, demonstrated best on the child and broken adult crania, suggest that Homo sapiens idaltu performed ritual mortuary practices of which the dimension, context and meaning might only be revealed by further discoveries.
