Cemental Deposition, Rooth Succession, and Horn Development as Criteria of Age in Dall Sheep
Hemming JE. 1969. Cemental Deposition, Rooth Succession, and Horn Development as Criteria of Age in Dall Sheep. The Journal of Wildlife Management. 33(3):552-558
Patterns of cementum, tooth succession, and external and internal horn annuli were studied in 129 specimens of Dall sheep (Ovis dalli). Fluoromicroscopy of annually produced cemental layers may be used to estimate age of all sheep older than 1 year. During the first 4 years of life age can be determined from the sequence of incisor replacement. Counts of annual horn increments provide a means of estimating age, but may be difficult to distinguish in older animals, particularly females.
