Hundreds of stone tools used by homo erectus a million years ago discovered in abandoned Sahara mine
World’s first mancave? Hundreds of prehistoric stone tools discovered in abandoned goldmine in Sahara may be ONE MILLION years old
- A gold rush in Sudan has led to numerous open-pit mines in the Eastern Desert
- Miners found hand-axes, almond-shaped cleavers and other tools
- Workmanship on the tools dates them to 700,000 to a million years old
- Because stone flakes were also found, its believed the site was a tool workshop
- The site is the oldest confirmed example of tool-making in the Eastern Sahara
Hundreds of stone tools that were crafted by homo erectus and discovered in a gold mine in the Sahara desert are believed to be up to a million years old.
The trove of hominid artifacts were uncovered by miners in northeastern Sudan.
They include almond-shaped cleavers and hand axes with a transverse cutting edge.
Archaeologists theorize the site was a workshop of sorts, because stone flakes formed during their production were also preserved.
It’s believed to be the oldest confirmed example of tool manufacturing in the Eastern Sahara with a well-confirmed chronology.

The prehistoric ‘tool shed’ was uncovered in an abandoned gold mine about 45 miles east of the city of Atbara in the Eastern Desert Atbara River (EDAR) area.
A gold rush in the eastern Sahara has led to numerous open-pit mines being excavated, giving archaeologists a rare opportunity to examine exposed layers of sediment.
Miners found tools called splits, which have a transverse cutting edge that resemble a fist, and almond-shaped cleavers with beveled edges on both sides.
Because stone flakes known as debitage were discovered along with the finished tools, archaeologists believe the site was a workshop for manufacturing stone tools.

Optically stimulated luminescence (OSL), which uses the last time quartz sediment was exposed to light, dates layers of earth and sand just above the tools to about 390,000 years ago, according to the researcher’s findings, published in the journal Plos One.
‘This means that the layers below are certainly older,’ said lead author Mirosław Masojć, a researcher with the University of Wrocław’s Institute of Archaeology.
‘Based on the style of workmanship of the tools, I believe that they may be over 700,000 years old — perhaps even a million years old – similar to their counterparts in South Africa.’

That would make the mine the oldest known example of tool manufacturing in the Eastern Sahara with a well-confirmed chronology.
‘Ancient tools are found in deserts, but never before have they come from layers that we can safely determine their age,’ Masojć said.
The cleavers found in the mine are typical of findings in Ethiopia and Kenya that date back a million years, Masojć said.

Impact pits in the mine suggest the site was also used for working wood, bone and other materials.
Palaeolithic artifacts used by both Homo erectus and Homo sapiens have been found in some 200 sites in the region.
The most recent are about 60,000 years old, while the oldest date to 500,000 years ago.

‘Now we have confirmation that there are monuments in this area that are perhaps even twice as old,’ Masojć said.
It’s possible deeper parts of the mine contain even older tools, but the unstable political situation in the region has made access difficult.
Homo erectus first emerged in the context of climate change and receding forests in equatorial Africa some two million years ago.
It was the first hominid species to exhibit humanlike proportions and gait, with a flat face, prominent nose, and sparse body hair.
