Abstract
Intrapopulational variation was studied for 141 Adjidaumo and 33 Paradjidaumo specimens of the rodent family Eomyidae from an Early Oligocene site at the Flagstaff Rim locality, Natrona County, Wyoming. Variability of crown patterns and molar lengths and widths for each genus was examined . Results of the study revealed that mandibular and maxillary molars one and two were least variable; premolar four and molar three varied the most . Coefficients of variation for the mandibular and maxillary teeth combined ranged from 4.8 to 10 . 4 for Adjidaumo and 2.7 to 11 . 9 for Paradjidaumo. There was high degree of variation in the crown patterns of mandibular and maxillary teeth of both genera . Specimens of Adjidaumo were identified as A. minimus and specimens of Paradjidaumo were identified as P. alberti .
