The Richat Structure, a prominent circular feature in the Sahara desert of Mauritania near Ouadane, has attracted attention since the earliest space missions because it forms a conspicuous bull's-eye in the otherwise rather featureless expanse of the desert. Described by some as looking like an outsized ammonite in the desert, the structure, which has a diameter of almost 50 kilometres (30 miles), has become a landmark for space shuttle crews. Initially interpreted as a meteorite impact structure because of its high degree of circularity, it is now thought to be a symmetrical uplift (circular anticline or dome) that has been laid bare by erosion. Paleozoic quartzites form the resistant beds outline the structure.

Could it have some sort of extraterrestrial origin? Does anyone have more information about this enigmatic structure?

There are actually three craters that form a line across the desert. Check 'em out.
Follow the line of craters

Don't know if there is anything under it and the two other craters support the meteorite explanation for the Richat Structure.

Sure, there could be. But perhaps we should exhaust prosaic explanations first before seeking the extraordinary.
