Every Artifact is classified by MaterialType, which drives analysis, curation, and NAGPRA screening. CERAMIC covers pottery and fired clay. LITHIC covers stone tools and debitage. BONE_FAUNAL is animal bone, while BONE_HUMAN is human skeletal remains and triggers special handling. SHELL covers worked or food-refuse shell. METAL, GLASS, and TEXTILE name those manufactured materials. BOTANICAL covers preserved plant remains such as seeds or charcoal. OTHER is used for anything that does not fit the defined categories. The BONE_HUMAN value in particular flags potential NAGPRA-sensitive material.
