Hand-carved from solid sandstone over 2,000 years ago, this massive underground network consists of 24 colossal caverns featuring soaring ceilings, uniform chisel marks etched at precise 60-degree angles, and remarkable structural integrity. Despite the excavation of over a million cubic meters of rock, no historical records of their construction exist, no ancient tools have ever been recovered, and there is no trace of where the displaced stone went—leaving scientists and archaeologists endlessly debating their true purpose

It is a limestone block carving originally painted with red ochre. The figure holds a crescent-shaped horn, often interpreted as a symbol of fertility or a lunar calendar due to the thirteen notches etched into it. At the Museum of Aquitaine in Bordeaux, France.

Its walls contain hundreds of engravings, including mammoths, bison, horses, rhinoceroses, birds, and rare stylized human figures. The cave is especially unusual because it also contains human remains from the same Gravettian period, making it both a decorated cave and a place connected to prehistoric burial practices. Often called the “Venus of Cussac,” this figure shows how a few carved lines could preserve a human presence across millennia.

The figures depict humans with bent limbs, leading researchers to believe they are portrayed swimming, suggesting the Sahara was once a green, wet landscape. In 2007, Eman Ghoneim discovered an ancient mega-lake buried beneath the sand of the Great Sahara in North Darfur, Sudan

The cow horn, which has been radiocarbon dated to between 1461 and 1630, was found covered with a leather lid and wrapped in leaves and grass. A team led by University of Johannesburg archaeologist Justin Bradfield analyzed residues from the container. They concluded that the residues contained high concentrations of the chemical compounds mono-methyl inositol and lupeol, both of which are used to control blood sugar and cholesterol levels, lower fevers and soothe inflammation, and treat infection. The team determined that three local plants could have been the source of the chemicals. Bradfield says the container is the earliest evidence from southern Africa of people combining two or more plants for the purposes of medicinal treatment. “We know that for tens of thousands of years people have understood the medicinal and toxicological properties of plants,” he says. “But until now we haven’t had tangible evidence that they were combining extracts from several plants to create a medicinal recipe.”
