Diagnosis

|---|---|---|
| B. J. Shockey and F. Anaya-Daza 2004 | aller than Pyrotherium romeroi; linear di- mensions of the cheek teeth being but two-thirds those of P. romeroi (Fig. 2; Appendix). Premolars differ from those of P. romeroi by presence of a well-defined cuspule in valley sepa- rating anterior and posterior lophs. It appears in valley on me- dial side of P3-P4 and frequently, though less distinctively, on M1 and laterally on p4-ml. Anterior transverse lophs of P3- P4 curve in the posterior direction on the labial side of the teeth. |
