Diagnosis
ReferenceDiagnosis
C. d. Muizon and D. P. Domning 2002Odobenocetops leptodon differs from O. peruvianus in the morphology of the snout, which is more rounded and wider in dorsal view; in the lack of large premaxillary foramina; in the presence of small depressions for premaxillary sacs in the premaxillae, anterior to the bony nares; in the presence of supplementary rostral bones at the anterodorsal apex of the snout; in the broader, deeper, and longer palate; in the anterior border of the palate, which is more U-shaped, while it is more V-shaped in O. peruvianus; and in the straight (or slightly concave) anterodorsal border of the orbit, which is deeply concave in O. peruvianus.
