American Antiquity, 1968
AbstractA Late Prehistoric period buffalo kill and butchering site in northern Wyoming (Site 48 JO 312) produced a large number of stone tools.

Tools for Thought: Some Comments on the Analysis of Puebloan Chipped Stone Assemblages

KIVA, 1982
ABSTRACTUsing chipped stone assemblages from five Puebloan sites located in central Arizona, an analysis of both tools and waste materials was recently undertaken as part of the Arizona Public Service Cholla Project. Based on this study we suggest that much of the use of chipped stone was opportunistic and that few formal tool types exist. Viewing data
