Evaluation of a tooth-wear age index for brushtail possums, Trichosurus vulpecula

The authors tested a set of criteria established by Winter (1980) for assessing the age of live brushtail possums, based on wear on the upper first left molar. A series of 69 skulls of known-age animals of all ages up to 13 years was used to evaluate Winter’s age index. Overall, the tooth-wear index gave a reasonable estimate of true age to within 1.0-1.5 years.
