They are, moreover, of very nearly even height throughout the series, and in their configuration present a remarkable and gradual transition from the first incisor to the last molar, easily traced in both jaws, and more even and regular than in any other known heterodont mammal.

However, Campagno (1977) has recently attempted to show that hybodonts belong to a more derived position within the euselachians, specifically being allied with the galeoid oryctoloboids and lamnoids. If this is the case, the absence of the orbital process in heterodonts might be considered a highly derived condition and the overall close similarity of the palates of the two groups a convergence due perhaps to a common pattern of fore-and-aft jaw movements.
