Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| Garcia Moreno 1986 | Megacricetodon larger than M. minor and smaller than M. crusafonti. The anterolophid is simple in 50% of the molars, it is divided into two cusps in 25 % of the cases, and is slightly split in 25 % of the cases.
The anterocone is split in 70 % of the specimens, being slightly split in the rest of the cases. The mesolophid is frequently absent, but a short mesolophid may be present. There is often a short mesoloph, but in some cases it may be long or it may be absent. In the M2, the internal valley is frequently directed forwards, and rarely it may be transverse. The posterolophid is always long. In the M1, there is often a short posteroloph, but long and absent posterolophs may appear with significative frequency. In the M2 the posteroloph is long. |
