The determination of the age of elephant ivory is a crucial aspect in the fight against illegal ivory trade which is still a relevant problem having triggered the decline of elephant populations due to poaching in different areas of the globe. Indeed, the absolute dating of the ivory allows, in forensics practice, to establish whether a determined sample or object was obtained and imported illegally, violating the international trade ban. In this frame the use radiocarbon dating has surely a great potential and is widely used. In this paper we review the potential of the method in this field, highlighting its advantages and drawbacks. In particular we show, through the discussion of real cases, how it is possible to improve the achievable chronological resolution by refining the obtained ages trough the proper use of available information and considerations.
象牙年代的测定是打击非法象牙贸易斗争中的一个关键方面，非法象牙贸易仍是一个相关问题，它已导致全球不同地区的大象种群因偷猎而数量下降。事实上，在法医学实践中，象牙的绝对年代测定能够确定某个特定样本或物品是否是非法获取和进口的，是否违反了国际贸易禁令。在此框架下，放射性碳年代测定法无疑具有巨大潜力且被广泛应用。在本文中，我们回顾了该方法在这一领域的潜力，突出其优点和缺点。特别是，我们通过实际案例的讨论表明，通过合理利用现有信息和考量因素来细化所获得的年代，从而提高可实现的年代分辨率是可行的。
