Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| F. G. Marx et al. 2019 | Shares with Tranatocetus argillarius its large overall size, slender ascending processes of the maxillae that are situated centrally on a triangular platform formed by the frontals, a narrow but continuous exposure of the nasals between the ascending processes of the maxillae, the lack of an external occipital crest, a bulbous exoccipital, an elongate anterior process of the periotic lacking a lateral tuberosity, a large paroccipital concavity, a large mandibular fossa housing a flattened platform in its posterodorsal corner, a deep subcondylar furrow, and a mandibular condyle that does not markedly rise above the level of the mandibular neck. Differs from T. argillarius in having a more anterolaterally directed base of the supraorbital process of the frontal, a more robust zygomatic process of the squamosal, relatively larger occipital condyles projecting posteriorly beyond the posterior apex of the nuchal crest, a vomerine crest extending posteriorly far beyond the level of the subtemporal crest, and a sharper, dorsally convex ventral border of the mandibular foramen. |
