In the article Large-scale faults and craters that destroyed the ancient civilization in the Sahara, examples of maps were shown where the Sahara, the entire north of Africa, more recently, is a territory with a different arrangement of rivers and, possibly, a climate. I don’t think this is the fantasy of the cartographers of the time. Something happened, that huge expanses turned into sandy deserts:

Interesting information on the same topic:
Under the sands of Mauritania, scientists have discovered a large ramified river system that once flowed through Western Sahara. The river bed was found using radar images obtained from the Japanese ALOS (Advanced Land Observing Satellite) satellite. In the photographs, scientists noticed ancient canals under the sands of the Sahara.
With the help of equipment, it is possible to find this ancient system of rivers under the sands.
My hypothesis of what happened: huge volumes of water emerged from the bowels of the Earth. With sand, clay and other masses that quickly petrified. Volcanoes erupted in the same way, degassing funnels formed. It is possible that the combustion of silanes added a decent amount of sand and water. The wave of the flood could not throw sand from the ocean. Sahara is located 500 m above sea level.

Here are the likely exits of water in the past:
Science is silent about these numerous craters. They're bigger than the Arizona Crater, though. In the center of some there are still lakes.
Here is a map that says that there is a lot of water in the Sahara, but it is in the underground seas and artesian aquifers. M. Gaddafi drilled wells and pumped water through huge concrete pipes, artificial rivers:
In the lower left corner of the picture there is a diagram of the underground seas of the entire north of Africa. Underground, almost everywhere in the Sahara there is water.
Productivity of aquifers excluding underground seas. In some places, these underground waters come to the surface and form reservoirs, oases in the middle of the sands:
An oasis in the Libyan desert - just above the underground seas. This one, apparently, is located along a fault through which water under pressure comes out to the surface.
This reservoir of the oasis follows the contour of the mud-water volcano. But the water also keeps coming out. If this were not the case, the water in this climate evaporated in a few days.

I don’t know how for everyone, but for myself, comparing all these facts (in the article they are far from the only ones), an increasingly clear picture of what happened is emerging. The reason for these events, which changed the face of the north of the African continent, remains a mystery.
