Diagnosis
ReferenceDiagnosis
J. H. Geisler et al. 2017Coronodon has the following mysticete synapomorphies: supra- occipital level with temporal fossa (character 25: state 1), broad basioccipital crests (39: 2), all cusps of posterior teeth subequal (99: 1), upturned antorbital process of maxilla (100: 1), and splayed basal cusps on posterior teeth (206: 1) (Figures 1, 2, S1, and S2; Data S1). Like some archaeocetes [8], its rostrum is twisted counterclockwise in anterior view (Figure 3). Corono- don havensteini is unique in having anterior lower molars labially overlapping posterior lower molars (Figure 2).
