Database E.3 Individual Records of Cranial Non-metric Variation in Adolescents and Adults

This database is part of Appendix E, from Ban Chiang, a Prehistoric Village Site in Northeast Thailand, Volume 1: The Human Skeletal Remains (tDAR ID #: 376592). Database E.3 contains non-metric observations (Cranial Non-metric Variation in Adolescents and Adults) by individual burial excavated from the BC and BCES locales at Ban Chiang, Thailand.
