Description: Comparison of teeth between Janjucetus hunderi, Lobodon carcinophaga, and Canis lupus dingo. Tooth sharpness in marine mammals varies among species. Comparison of the postcanine teeth of (a) an extant terrestrial carnivoran, the dingo Canis lupus (NMV C25871, mirrored), with that of (b) an extant seal known to employ tooth-based suction filter feeding (crabeater seal, Lobodon carcinophaga, NMV C7392), and (c) the extinct toothed mysticete †Janjucetus (NMV P252376; see electronic supplementary material for diagnosis). Note the sharp cutting edges in the dingo and †Janjucetus. Three-dimensional surface models not to scale.
