IDENTIFICATION OF HAFTING MATERIAL AND RADIOCARBON DATING FOR TWO AVONLEA PROJECTILE POINTS, WORTHAM SHELTER, WYOMING (2011)
DOCUMENT Full-Text Linda Scott Cummings. Chad Yost.

Two Avonlea projectile points from Wortham Shelter that still had existing hafting material were submitted for protein residue analysis and AMS radiocarbon dating. Both of these projectile points and their hafting had been coated with shellac or a similar substance, which necessitated cleaning the artifacts prior to analysis. Protein residue analysis was undertaken to identify the proteins in the hafting material, and, thus, the animal that the sinew was taken from.
