Abstract
An examination of a section of the horn sheath of Japanese serow (C. crispus) showed that the number of growth layer in the keratinized zone correlated with age. Patterns of cementum annulation were also valid criteria for accurately estimating age. These methods were confirmed by using 18 known-age samples. The reliability of horn ring counts was checked by annulations in both horns and teeth and were found to be a useful means of estimating age.This publication has 1 reference indexed in Scilit:
