Archaeology
Over sixteen megalithic standing stones were discovered by Edward Keall, director of the Royal Ontario Museum's Canadian Archaeological Mission near the village of al-Mutaynah in the Tihamah area. The stones were made of granite and weighted up to 20 tonnes (20,000 kg). Three of the upright sotones measured around 8 feet (2.4 m) tall with one fallen being over 20 metres (66 ft) in length. Copper tools suggested to date to the same era as the construction of the stones were dated to around 2400 to 1800 BCE. An even more archaic lithic industry was found along with pottery sherds that were dated between 1200 to 800 BCE.
