[1] The members of the Valley of Oaxaca Settlement Pattern Project and their colleagues have now walked over the largest contiguous archaeological survey region in the world, more than 8000 sq km.
Overall, Feinman has conducted research in the Valley of Oaxaca, Mexico for over 40 years, most recently in the lands of the communities Tlacolula, Mitla, Matatlán, and Ejutla.
The team has documented a large segment of the ancient Qi Great Wall, which was built during the Warring States period, and ultimately was breached by Qin armies just prior to the first unification of China.
In addition to drawing on results from survey and excavation, Feinman, in conjunction with Linda Nicholas, Mark Golitko and colleagues from Mexico and the United States, has begun an effort to greatly increase the quantity of sourced obsidian from documented prehispanic contexts in the Valley of Oaxaca.
He also served as curator for a number of temporary exhibitions, including Chocolate, The Aztec World, China's First Emperor and His Terracotta Warriors, Death: Life's Greatest Mystery, and Mexican Nativity Scenes.
With T. Douglas Price, Feinman is the author of the amply illustrated world prehistory text, Images of the Past, which presently is in its 9th edition.
