Gold, copper, shell, and lapis goods were found in many of the stone-marked infant/child graves.
This involved the movement of finished goods and raw materials, including chank shell, lapis lazuli, turquoise and ceramics.
This was the main source of lapis lazuli in the ancient world, with lapis from here occurring in such famous archaeological discoveries as the Royal Treasure of Ur and the Tomb of Tutankhamun.
