Tusk Weight-Age Curve
Definition
A species- and sex-specific regression of tusk mass against age, derived from known-age wild elephant records. Allows investigators to estimate the age at death of an elephant from its tusk's mass and length.

Common questions
Why is a species- and sex-specific curve necessary rather than one general formula?+
Tusk growth rate and final mass differ between elephant species and between males and females of the same species, so applying a mismatched curve would produce a biased age estimate for wildlife forensic casework.
What forensic question does tusk age estimation typically support?+
It helps investigators assess the maturity of an animal killed for ivory, which can bear on wildlife protection charges, poaching pattern analysis, or corroborating a trafficker's claims about the source of seized tusks.
