ABSTRACT
Shape Within the small sample of vessel-rim lots in Assemblage 4, as well as the supplemental material from other fairly good contexts, the uniformity of vessel shape is striking. Excluding one rim suspected to be an intrusive Saladoid specimen, all of the upper walls that can be identified to contour are convex (Figure 5.20). The stance of the convex upper wall most commonly is inward sloping (from mid-wall to orifice). In some cases it is vertical (upright) at the rim (unrestricted), and one case is possibly outward sloping. Among all the sherd-units of the assemblage, more than half have convex contours. A minor number have a straight contour, which may include flatbased sherds. Many are too small or uneven reliably to show wall contour, but none exhibits a concave contour. No exterior angles in vessel wall contour (corner points of contour) could be clearly identified. These characteristics contrast sharply with the Saladoid assemblages.
