BRACELETS IN THE SAHARA
In the center of the Sahara I found some structures that look like bracelets. Since I assume that these are also old graves, I called them "bracelet graves". Although they have a central rotunda with two arms extending from them, they don't seem to fit in with the large family of antennae graves. I haven't seen these strange shapes anywhere else on the internet either. What are they? How old or young are they? does anyone know more?

Even the renowned specialist for prehistoric Sahara monuments Yves Gauthier could not tell me anything about these structures. He himself has a few dozen of them in his database, but he doesn't know more than that they exist, he told me when I asked. So far, he is not aware of any scientific publication about it or whether a name is already in use for it somewhere.
