Ages Assigned Known-Age Texas White-Tailed Deer: Tooth Wear Versus Cementum Analysis
Cook RL and Hart RV. 1979. Ages Assigned Known-Age Texas White-Tailed Deer: Tooth Wear Versus Cementum Analysis. Pages 195-201. In Proceedings of the Annual Conference Southeastern Association of Fish and Wildlife Agencies
Incisors and jawbones were collected from known-age Texas white-tailed deer (Odocoileus virginianus texanus) which had been captured, ear-tagged, and released as fawns and harvested during public hunts in subsequent years. Incisors from 25 known-age whitetails were aged by Matson's Commercial Microtechnique Labratory using the cementum analysis technique. The jawbones from these same 25 deer were aged uring the tooth replacement and wear technique by wildlife biologists/wildlife technicians of the Texas Parks and Wildlife Department. Matson correctly aged 4 (16%) of the 25 known-age incisors. Ninteen (90.5%) of the incorrect ages assigned by Matson were younger than the known age. Biologists/technicians correctly aged 242 (66.7%) of 363 possible assigned ages using the tooth replacement and war technique. Ninety-two (76%) of the incorrect ages assigned by the biologists/technicians were older than the known age.
