Abstract:Abstract Recently, the Urmia salamander, Neurergus crocatus Cope, 1862 was classified as a vulnerable species. The age structure of a breeding population portion of N. crocatus from Turkey was studied by using skeletochronology performed on the phalanges. According to the analysis of the age structure based on counting lines of arrested growth (LAGs), ages ranged from 5 to 14 years (mean?=?9.4 ± 2.3 years) for males and from 8 to 17 years (mean?=?11.6 ± 2.2 years) for females in N. crocatus. The mean snout?vent length was 69.2 ± 3.6 mm in males and 76.2 ± 3.8 in females. The sexual dimorphism index was 0.10. The difference between the sexes in age and size was statistically significant.Abstract Recently, the Urmia salamander, Neurergus crocatus Cope, 1862 was classified as a vulnerable species.
