The work of the Central Zagros Archaeological Project in 2008 was focused on the transition from hunter-gatherer to farmer-herder in a key region, the Zagros zone including central west Iran. The 20 papers in this Report contribute to studies of early sedentism, animal domestication and agriculture, and cover a variety of topics including caves and rock shelters; objects of bone, stone and clay; human burials; and plant macrofossil evidence.
