<jats:p>Trace element analysis is a widely used procedure for determining the original source of archaeological materials. Although many articles have discussed analytical procedures and archaeological applications of the results, comparatively little attention has been given to the intermediate step of determining the appropriate procedure for assigning an artifact to a source once the trace element composition of both is known. This paper discusses several different procedures for assigning artifacts to sources and compares these procedures on the basis of their accuracy and the types of identification errors they make. Special attention is paid to discriminant analysis, which appears to be the best procedure for identifying sources of chert artifacts.</jats:p>

<jats:p>The Chumash tomol, a sophisticated planked canoe, came into use in the Santa Barbara Channel region of Southern California about 1,500 years ago. It is often assumed that planked watercraft were first developed in the region at about that date. This paper argues, on theoretical grounds, that planked canoes were developed much earlier in Southern California, perhaps as early as 8,500 years ago.</jats:p>

<jats:p>The neutral model of stone procurement developed by Brantingham (2003, 2006) provides a formal means to investigate the formation of lithic discard patterning under changing forager mobility conditions. This study modifies Brantingham's (2006) Lévy walk model to examine the influence of discard probability on the spatial distribution of raw material abundance. The model outcome shows that forager movement and tool discard probability have similar effects on the simulated patterns of raw material transport, so it is difficult—if not impossible—to differentiate the respective influence of the two factors from distance to source distributions alone. This finding of equifinality complicates the task of interpretating hominin mobility from archaeological distance to source data, particularly in settings such as the Middle-Upper Paleolithic transition, which is marked by an important reorganization in hominin lithic technology that may have affected stone tool discard probability.</jats:p>
