Differentiating bamboo from stone tool cut marks in the zooarchaeological record, with a discussion on the use of bamboo knives

The archaeological record of Southeast Asia is marked by a relative lack of Acheulian assemblages compared with the rest of the Old World. Suggestions that prehistoric human populations in this area relied instead on a non-lithic technology based on bamboo have not been supported by archaeological evidence. To provide a diagnostic means of assessing prehistoric use of bamboo, cut marks were experimentally produced on bone using chert tools and bamboo knives. A scanning electron microscope (SEM) examination revealed morphological differences in cut marks produced by the two materials that allow identification of bamboo knife cut marks on faunal materials. Such evidence, if found in Pleistocene through early Holocene archaeological sites in Southeast Asia, would indicate early human reliance on bamboo technology.
