on 木葛

-This is essentially the foundation of a hut. It is unimaginable to see an actual house structure right there next to what is now nothing.

Hassan’s discovery is striking evidence of human habitation.

-The house structure consists of this: circular foundation with upright standing rocks which are taken from the local bedrock. It would have made a semi-circular structure with probably skins and branches and people would have used that as a shelter.

Hassan believes these huts could have housed a small community of around 50 people. Now he needs to know exactly when they lived here.

-Ostrich eggshell beads.

These little ostrich egg beads are clearly human handiwork.

-They used the eggshells to make ornamental beads. Cut into a circle so that a strain can pass through. So they strain this into bracelets / or necklaces.

The eggshells the beads were made from are also here and provide the next clue.

-The eggshells suggest, of course that there were ostriches, and that’s quite remarkable for this environment to have animals like that.

This was no nomadic tribe but a settled farming community rearing animals for food.

Hassan carbon dated the ostrich eggshell beads. The result: just 7,000 years ago, the deadliest desert on earth was home to both human and animal life. It’s dramatic evidence of the last burst of green in the desert. A dip in the desert floor provides a clear sign that rain from the monsoon fell here.

-What we have here is the evidence of a deep lake with mud deposited.

This mud indicates a body of water that could have supported a settlement of people.

-When the lake is deep as we can see from these layers here, there would / be a lot of vegetations, a lot of animals and people would have a very good time.

At sites all across the Sahara, scientists have excavated similar evidence of life, the remains of elephants and gazelles, hippos and crocodiles. Remarkable cave paintings even show people swimming. Elsewhere, human bones have been found carefully buried in what were lake side graveyards. Analysis of these bones reveals they date from between 10,000 and 6,000 years ago.
