Toyah sites in Texas indicate a marked increase in bison exploitation between A.D. 1300 and 1650, and yield significantly more end-scrapers and other hide-processing tools than earlier sites. Hide-processing assemblages from the Pampopa-Talon Crossings Site (41BX528) and several others in south-central Texas differ from most Toyah sites in that middle and late hide-processing stages are unusually well-represented. Selection of places on the landscape for intensive hide-processing activities is examined in the context of ecological, ethnohistorical, geographical, and lithic-analysis studies. The project area setting along major travel corridors suggests that trade may have been an important factor for the presence of these distinctive hide-processing assemblages
