The Predynastic and Early Dynastic cemetery of el-Amra contained over a 1,000 burials. The site’s distinct material culture led to material being described as Amratian (=Naqada I). Material remains like stone vessels indicate trade with the north of Egypt and either Sinai or Nubia on account of copper, obsidian and gold.
