One good example of ethnoarchaeology is that of Brian Hayden (1987), whose team examined the manufacture of Mesoamerican quern-stones, providing valuable insights into the manufacture of prehistoric quern-stones. Many other studies have focused on the manufacture and use of ceramics, architecture, food, fiber, and other types of material culture. In the best cases, these studies have involved long term ethnographic fieldwork (for example, Herbich 1987, Kramer 1997, Deal 1998, Dietler & Herbich 1998, Hinshaw 2000, Longacre & Skibo 2000, Kohn 2010).
