7 months ago12,000-Year-Old Life-Sized Camel Etchings Reveal a Lost World in the Desert
Newly discovered prehistoric artwork suggests how a pioneering sect of desert nomads, unknown to history until now, carved out an existence about 12,000 years ago in the harsh environment of northern Arabia. At four remote sites near Saudi Arabia's Nefud Desert, researchers are puzzling over 130 life-sized animal images emblazoned on rocky outcrops. Wild camels dominate the carvings: 90 of them run alongside other ancient beasts that once roamed the arid landscape.
