In this study, the age structure of an Asaccus barani sample from Sanliurfa (southeastern Anatolia, Turkey) was determined by skeletochronology for the first time. A total of 17 preserved adults (7 males, 10 females) were evaluated, and the maximum observed lifespan was recorded as 6 years in males and 5 years in females. The first line of arrested growth was partially eroded by endosteal resorption in 29% of individuals and completely eroded in 18%. The mean age was 3.85 +/- 0.50 years in males and 3.80 +/- 0.32 years in females; the mean snout-vent length (SVL) was 46.99 +/- 2.64 mm (range: 37.78-54.13) in males and 46.89 +/- 1.51 mm (range: 40.33-53.19) in females. There was no significant difference between sexes in terms of age and SVL. However, there was a positive correlation between age and SVL in both males and females.
