摘要：In 2012, Perttula requested permission from to the Caddo Nation of Oklahoma's Repatriation Committee to analyze small samples (ca. 1-2 grams of ceramic paste, or sherds ca. 1-2 square centimeters in size) from the paste of five vessels from Features 31 and 95 at the Washington Square Mound site (41NA49) (Perttula et al. 2010) in East Texas to identify residue traces of the Caddo's use of peyote in the 13th-15th centuries A.D. The Caddo Nation of Oklahoma gave their permission to conduct these ceramic vessel residue studies.
