Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. W. Crompton 1964 | Mammal with a well developed condyle on the dentary. A groove in the dentary containing accessory jaw bones is present. The primary articulation between the articular and quadrate was presumably still present. Angle of the dentary extremely small. Boss
for the support of the coronoid bone absent. Slender coronoid process. Dental formula: 1 ? C ? PC ? 4(5) 1 6(7) Posterior lower postcanines similar to those of Morganucodon watsoni except that the cingulum cusps are less well developed. Upper posterior postcanines, unlike those of Morganucodon, consist of five cusps aligned antero-posteriorly. Anterior and posterior accessory cusps of the same size. |
