Prehistoric human crania from the Early Period Rossi and Saunders sites (Mnt-386/387 and Mnt-391) offer an opportunity to compare these remains with other early sites in California. The data for this analysis were derived from 107 crania from archaeological sites in the Lower Sacramento Valley, San Francisco Bay area, Monterey Bay area and Santa Cruz Island. Analysis of 19 metric variables using ANOVA tests and lateral cranial contour drawings of the craniofacial complex reveal that the Rossi and Saunders site females show a generalized morphological pattern, whereas the males display a craniofacial pattern consistent with that found in the Lower Sacramento Valley.
