Abstract

Here, we report on the results of microCT scanning and Accelerator Mass Spectrometry (AMS) radiocarbon dating of fragments of charred archaeological parenchyma collected from surface deposits at Nombe rockshelter in the highlands of Papua New Guinea. Five fragments are taxonomically identified as sweet potato (Ipomoea batatas). Two subsamples from the largest fragment yield a combined AMS date range of c. 300–148 calBP (with median probabilities of 187 and 195 calBP respectively). Although post-dating European voyaging in the Indo-Pacific, these findings contribute to the corpus of information regarding the antiquity of sweet potato on the island of New Guinea.

巴布亚新几内亚高地Nombe岩洞中烧焦甘薯(Ipomoea batatas)碎片的微ct扫描和直接AMS测年

在这里，我们报告了microCT扫描和加速器质谱(AMS)放射性碳定年的结果，这些烧焦的考古薄壁组织碎片收集于巴布亚新几内亚高地Nombe岩库的地表沉积物中。其中5个片段经分类鉴定为甘薯(Ipomoea batatas)。来自最大片段的两个子样本产生的综合AMS日期范围为约300-148 calBP(中位数概率分别为187和195 calBP)。尽管欧洲人在印度-太平洋的航行时间晚了，但这些发现有助于提供有关新几内亚岛上红薯古代的信息。

期刊介绍： Archaeology in Oceania is published online and in print versions three times a year: April, July, October. It accepts articles and research reports in prehistoric and historical archaeology, modern material culture and human biology of ancient and modern human populations. Its primary geographic focus is Australia, the islands of the Pacific Ocean and lands of the western Pacific rim. All articles and research reports accepted as being within the remit of the journal and of appropriate standard will be reviewed by two scholars; authors will be informed of these comments though not necessarily of the reviewer’s names.
