Among them are human skulls. Huge piles of bones in the Umm Jarasan Cave in Saudi Arabia

Weather of Arabia - A large pile of bones was found on an expedition to the Umm Jarasan Cave in Harrat Khaybar in Medina, Saudi Arabia, and the remarkable thing is that among these bones are a number of human skulls.

The discovery was made through an exploratory trip carried out by the Saudi Heritage Authority, in cooperation with the Saudi Geological Survey, King Saud University, and the German Max Planck Institute.

After the study, it was found that these bones belong to 14 different types of animals, along with human bones collected over the last 7,000 years.

Among the animals whose bones were found were "the striped hyena, horses, wild and domestic donkeys, wild and domestic camels, ibex, goats, and cows."

As for the human skulls, it is likely that they were exhumed from nearby prehistoric graves and collected inside the cave.
