LOS ANGELES, Calif. - PBS says “Antiques Roadshow” is dropping appraisals of ivory tusks. The tusks won’t be shown in new episodes or in segments drawn from previously aired shows, PBS said Wednesday.

Traffickers often disguise elephant tusks to look like mammoth ivory, which can be traded legally. Woolly mammoths went extinct in the last glacial period around 10,000 years ago.
