Changes in the use of ochre in Middle Stone Age Ethiopia depict a culture in slow transition, progressively replacing exotic iron-rich high-quality rocks with lower quality, poorer in iron, but locally available ones.
Research has shown that a wide variety of ochre types were collected and brought to the site to produce ochre powder of different textures and shades, probably adapted to different symbolic or functional activities.
The new study reveals a change in raw material preferences throughout the site’s occupations: the good quality ochre was more intensively sought at the beginning of the site occupation, while the use of lower quality ochre types gradually increased through time.
