Age and legality of ivory revealed by carbon-14 dating can fight poachers
Radiocarbon dating - Wikipedia
Scientists are using DNA analysis of ivory samples confiscated from the U. Two teams of scientists will use radiocarbon dating to determine when each elephant was killed and DNA analyses to locate where it came from in Africa. Determining the location and year an elephant that produced a tusk was killed establishes if the ivory being sold is legal, helps assess the current extent of poaching, and assists law enforcement in targeting the poachers responsible. Story by Sue Palminteri. The sale of ivory across international boundaries has been banned since , when the African elephant was listed among species prohibited for commercial trade, but the precious commodity still manages to find its way to buyers in Asia, Europe, and North America.
Radiocarbon dating used to convict two people for possessing illegal ivory
The sale of ivory across international boundaries has been banned since , when the African elephant was listed among species prohibited for commercial trade, but the precious commodity still manages to find its way to buyers in Asia, Europe, and North America. The United States buys more retail ivory than any country except China. Until , it allowed the import and domestic trade of antiques and ivory from elephants killed before the listing.
