MicroCT scanning and direct AMS dating of charred sweet potato (Ipomoea batatas) fragments from Nombe rockshelter in the highlands of Papua New Guinea
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.
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.
