Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. D. Carrillo et al. 2018 | The dental formula is i 2/3, c 1/0, p 4/4, m 3/3. Mandibular symphysis reaches the level of m1–m2. Comparable in size to Pericotoxodon, larger than Nesodon and Xotodon, and smaller than Toxodon and Mixotoxodon. Upper molars have simple enamel lingual fold. Well-defined protoloph lingual column present only in M3. It differs from Gyrinodon in the sigmoid shape of the zygomatic arch in lateral view, the broad metaloph, and the absence of a ventral extension of the dentary. It differs from Mixotoxodon in having a short diastema posterior to i3, lingual enamel band of m1 restricted between the anterior fold and the hypoconulid, a less developed lower molar anterior fold, and less procumbent lower incisors. It differs from Trigodonops in the absence of a labial groove in p3 and p4. It differs from Piauhytherium in having a long nasal and the presence of an upper canine. It differs from Pericotoxodon in the position of the infraorbital foramen, widely separated from the zygomatic arch, the absence of I3, the upper molars with a simple enamel fold, and the absence of a ventral extension of the horizontal ramus of the mandible. It differs from Andinotoxodon in the presence of p1, absence of lingual enamel in the lower premolars, and in having a labiolingually narrower entolophid. It differs from Hoffstetterius in the presence of the upper canine and P1, and the absence of a mandibular ventral extension. It differs from Paratrigodon and Trigodon in the presence of P1 and lingual enamel in P3 and P4. It differs from Calchaquitherium in the rounded angle of the posteroventral border of the vertical ramus of the mandible, the incisors being at the same level as the cheek teeth, and the absence of a median symphyseal labial keel. |
