The results of this radiocarbon analysis permit the conclusion that split-twig figurines and atlatl darts were in use essentially contemporaneously at Newberry Cave. The numerous Elko series and Gypsum type projectile points in the collection were undoubtedly used with the atlatl dart shafts. It seems probable that the apparent magico-religious artifacts and unique zoomorphic pictographs present on the walls of the cave also date from this period of use. It is suggested that this magico-religious and hunting assemblage comprises a single cultural component, and resulted from the activities of a prehistoric hunters' society, who attempted to aid their pursuit of bighorn sheep through the use of magic.
