Fig. 1 in Remarks On Correlations And Implications Of The Mandibular Structure And Diet In Some Seals (Mammalia, Phocidae)

Fig. 1. Right mandible of Recent Gray seal (Halichoerus grypus, NMNH 51488) in labial view with measured condyloid angle based on the inclination of the condyloid process to the alveolar line. The condyloid angle can be identified by the joining of a horizontal axis parallel to the base of the mandible, starting from the lower alveolar edge of the canine (as indicated by line a), vertical axis from the posterior edge of m1 to the base of the mandible (line b) and an oblique axis from the intersection of lines a and b to the tip of the condyloid process (line c).
