Abstract: Skeletochronology has become the most widely used method of ageing amphibians. However, bone remodelling, double lines and rapprochement of peripheral lines all hamper exact skeletochronological age determination. In a long-term field study, the age of long-lived Alpine newts (Ichthyosaura alpestris) from a high-altitude population was estimated from cross-sections of phalanges at the time of tagging with PIT tags and again 10–16 years later. The skeletochronologically assessed age at recapture underestimated the time since first capture by 2–19 years, and the observed deviance increased with increasing age estimates at first capture.
