Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| P. M. Butler and D. Sigogneau-Russel 2016 | Relatively large lower molar showing the morganucodontan disposition of b and the pres- ence of a g cusp. Differs from Morganucodon by cusp a relatively lower and less acute with a more convex mesial crest, the deeper incisures between the three main cusps, b as high as c but shorter mesio-distally, and presence of cusp f. In the morganucodontid Gondwanadon, which also has e and f cusps, b is larger than c, and the three cusps are less deeply separated. Differs from megazostrodontids in the proportions of the main cusps, the presence of f (except Dinnetherium), and the occlusal relations, which appear to be of Morganucodon type. |
