Remarks--The ectoloph of this tooth is strongly pigmented on the faces of the shearing blades below the postparacrista, premetacrista, and postmetacrista, but the pigment stops before reaching the base of the paracone and metacone.

DISCUSSION The material represents a didelphid because the metacone is larger than the paracone, stylar cusps A, B, C and D are present, although variable, the stylar shelf is wide, and the centrocrista is V-shaped.
Using these criteria, four age groups were identified, which were suspected to represent annual cohorts characterized as follows: 1) young adults--slight to moderate wear on paracone and metacone of P4, M1, and M2, but protocone only slightly worn, P3 with virtually no (or only slight) wear; 2) adults--distinct wear on cones of P4 and all molars but individual cones clearly separated from each other except on M3 (wear had obliterated divisions between some cones and styles), P3 moderately worn; 3) adults--cones no longer distinct on molars, some cone integrity remains on P4, top occlusal surface of P3 nearly flattened; 4) old adults--P3 appearing as a flattened peg, P4-M3 heavily worn, cones distinct (if present) only on labial margin of teeth.
