This is due primarily to the high degree of shape variation that occurs across the Perdiz type.

 <p>This effort shifts the scope of these undertakings to focus upon a smaller scale, providing a means of applying the tools of geometric morphometrics to the oft-fragmentary and incomplete elements of material culture regularly encountered in the archaeological record. The first of these studies is focusing upon variability in decorative motifs via Caddo ceramic incisions (<a href="https://aksel-blaise.github.io/incision/">https://aksel-blaise.github.io/incision/</a>), and a shift to analyses of standard vessel components would provide an additional means of developing and testing our conceptual arguments related to the Caddo cultural landscape.</p>
