Gov. Christie just sign into law a complete ban of any type of ivory products in NJ. The new state law bans "import, sale, purchase, barter, or possession with intent to sell" ivory from any species, including fossil ivory from mastodons and mammoths extinct for 10,000 years, and has no exceptions whatsoever. The ban will go into effect in six months, during which time anyone who owns antiques, musical instruments, guns, knives, canes, chess sets, art or anything else that contains even the smallest amount of ivory can liquidate it.
