|---|---|---|
| T. Kimura and L. G. Barnes 2016 | A genus of Allodelphinidae having depression on dorsal surface of posterior part of rostrum, wide dorsal opening of mesorostral canal anterior to nares, premaxillae extending posteriorly to position of nasal bones, premaxillae curving medially to constrict posterior ends of nasals, cranial vertex symmetrical, nuchal crest not greatly elevated or thickened, zygomatic process of squamosal relatively large and arc-shaped, and temporal fossa relatively small and tapered anteriorly; differing from Allodelphis by having depression on basal part of rostrum anterior to nares, nasal bones smaller and greatly compressed transversely between posterior ends of premaxillae, and smaller temporal fossa; differing further from Ninjadelphis, new genus, by having shallower depression anterior to nares, small anteroposteriorly aligned maxillary crest dorsal to orbit, posterior ends of nasal bones more constricted transversely, postorbital process of frontal shorter, temporal fossa smaller and more tapered anteriorly, shorter and more curved zygomatic process of squamosal, dorsal exposures of frontals at cranial vertex smaller, mesethmoid septum between posterior parts of nares shorter, posterior maxillary foramen positioned more anteriorly, occipital condyles more protruding posteriorly; and differing further from Zarhinocetus by lacking tuberosity on each maxilla anterior to antorbital notch, and by having wider dorsal opening of mesorostral canal on posterior part of rostrum, shallower basin on dorsal surface of rostrum anterior to nares, posterior ends of premaxillae extending posteriorly and ending lateral to nasal bones rather than being retracted anteriorly and terminating lateral to dorsal nares, nasal bones larger, exposures of frontals on cranial vertex smaller, cranial vertex symmetrical rather than displaced to left side, nuchal crest narrower and lower, and zygomatic process of squamosal short and very curved in lateral view rather than elongate and rectangular. |
