"This artefact is older than Acheulean cultures, I think that homo erectus 1 million-1,5 million is the maker. I have from Beegden and Boukoul the same images, its comes from the oldest phase, Very interesting piece Ken!!!" Jan van Es, January 21, 2015Palaeoart at Two Million Years Ago? A Review of the Evidence, James B. Harrod
“Zinj” is the name given to a 1.8 million-year-old skull of the Paranthropus boisei species found in 1959 in the Olduvai Gorge of Tanzania. Named after the original classification of the species, Zinjanthropus boisei, Zinj was the first one to be found belonging to this group of hominids. Paranthropus boisei lived in Eastern Africa from about 2.3 to 1.2 million years ago. They had a brain volume of about 500 to 550cc and they would have eaten seeds, plants and roots which were dug up using sticks of bones. Due to the strong jaw that would have also been used for cracking nuts, Zinj is also known as the ‘Nutcracker Man’. - See more
The slight bifurcation of the sculpture's head at the center top of the skull may be a reflection of an early hominid head form as seen in the similar indent in the top of this Paranthropus boisei reconstruction.
