Proboscidean remains have been documented in New England for well over a century, yet few radiocarbon dates exist for these animals in the region. Here, we report the first AMS radiocarbon date and stable carbon:nitrogen isotope analysis for the Mount Holly mammoth, Mount Holly, Vermont. Among proboscidean finds in New England the date of 10 860±30 (12 882–12 792 cal. BP) from the Mount Holly mammoth is the most recent radiocarbon date for a mammoth or mastodon in New England and the most precisely dated specimen possibly post-dating the accepted age of the initial human settlement of the region during the onset of the Younger Dryas. Stable nitrogen isotope values are low for mammoths both regionally and globally, but consistent with a pattern of falling δ¹⁵N values for mammoths following the Last Glacial Maximum with particularly low values during the Younger Dryas.

美国佛蒙特州霍利山猛犸象的首个 AMS 放射性碳日期和稳定 C:N 同位素分析

一个多世纪以来，新英格兰已经记录了长鼻目动物的遗骸，但该地区这些动物的放射性碳日期很少。在这里，我们报告了佛蒙特州霍利山猛犸象的第一个 AMS 放射性碳日期和稳定碳：氮同位素分析。在新英格兰的长鼻类发现中，来自霍利山猛犸象的 10 860±30 (12 882–12 792 cal. BP) 日期是新英格兰猛犸象或乳齿象的最新放射性碳日期，并且可能是最精确的年代- 在新仙女木出现期间确定该地区最初人类定居点的公认年龄。猛犸象的稳定氮同位素值在区域和全球范围内都很低，但与 δ ¹⁵下降的模式一致猛犸象在末次盛冰期之后的 N 值，在新仙女木时期特别低。
