This video was created by Dr. Sabrina Sholts of the Human Evolution Research Center at the University of California in Berkeley using 3D digital scans of a Clovis stone projectile point from the collections of the Department of Anthropology, National Museum of Natural History, Smithsonian Institution. Scans of Clovis stone points from the Smithsonian were the subject of the scientific paper "Flake scar patterns of Clovis points analyzed with a new digital morphometrics approach: Evidence for direct transmissions of technological knowledge across early North America," in an upcoming issue of the Journal of Archaeological Science, May 2012.
