Studies in functional and analytical graniology. 2. The functional classification of Mammalian Skulls

Abstract

The stresses exerted in the alveolar process are transmitted onto other parts of the skull by means of arches or resisted lacally. The arches are: (a) long, (b) short, and (c) flat. Accordingly, the functional taxonomy of the mammalian skull is based on the conception of the breviarcuate skull (short arch), the longoarcuate skull (long arch), and the planoarcuate skull (flat arch). The structural evolution of these types from the primitive skull is illustrated and described.
