Hoogland, John L. and Hutter, Janice M. 1987. Using Molar Attrition to Age Live Prairie Dogs. Journal of Wildlife Management 51. pp 393-394.

Abstract

Molar attrition was examined in 153 live black-tailed prairie dogs (Cynomys ludovicianus) of known ages determined from a history of permanently marked juveniles. Based on tooth wear, molars were assigned to 3 age classes: 0.5, 1.5, and ³2.5 years. Molar attrition predicted the coorect age class for 86% (131 ÷ 153) of individuals.
