Nearly 25 years after an international ban was placed on ivory, African elephants are being slaughtered at a rate that could bring about their extinction this century. By allowing the trade of ivory acquired before 1989 to continue, the ban put the burden on law enforcement to distinguish between legal ivory and poached. Now, a new method for dating elephant tusks, described in the latest issue of the Proceedings of the National Academy of Sciences (PNAS), could make it easier to enforce the ivory ban and save the African elephant from extermination say researchers. The method might also be applied to endangered rhinoceroses and other wildlife.
