Figure 19 in Description of a new long-snouted beaked whale from the Late Miocene of Denmark: evolution of suction feeding and sexual dimorphism in the Ziphiidae (Cetacea: Odontoceti)

Figure 19. Boxplot of the ratio AL/TL between the length from the posterior end of the alveolar groove to the posterior end of the mandible (AL) and the total length of the mandible (TL). The circled data correspond to the two long-snouted fossil ziphiids Messapicetus gregarius and Ninoziphius platyrostris, the most similar in size to Dagonodum mojnum gen. nov., sp. nov.
