Carbon dating rhino horn

Published: 11.05.2018

Nuclear fallout from Cold War nuclear tests could help to identify poached ivory. Correct age determination with radiocarbon dating is based on calibration curves which provide the variations of atmospheric 14C content in the past. Why Bother Being Nice?

As a consequence, the atmospheric 14C content increased enormously reaching a maximum at around For tissues formed before , the technique is much more uncertain, perhaps getting a death date wrong by more than 17 years.

Uno's team, including biologists and geologists from the U. Poached Ivory TRACE, an international collaboration of campaigners, enforcement agencies and forensic scientists set up in , believes the technique can be used successfully in future against illegal wildlife trading like that in tiger body parts, rhino horn and scrimshaw. Back to the scene:

We have to legalise trade in rhino horn: John Hume at TEDxJohannesburg

By Mic Smith Following the recent auctions of rhino horn items in Melbourne and Sydney, the Australian Department of Environment has said it works closely with auction houses on upcoming sales of rhino horn.

The spike of carbon after the ivory is analysed is quite unique if it was posts. We need to change and adapt to CC to save the reef. More temples than houses.
