This paper details the initial steps in the development of a virtual database for archaeological parenchyma, including the protocol for scanning and reconstruction. The protocol enables high-resolution 3D virtual reconstruction for classification and comparison. The aim is to ensure replicability of analysis and standardization of the database.
The investigation of archaeological parenchyma derived from underground storage organs (USOs) is under-represented in archaeobotany globally. Although some regional reference collections have been assembled and applied to archaeobotanical materials, these are not generally accessible to researchers. Here, the initial steps in the development of a virtual database for archaeological parenchyma are detailed. Foremost, a protocol for the microCT scanning and virtual reconstruction of modern reference material and also of archaeological parenchyma is detailed. The protocol enables a 3D virtual representation of scanned materials to be recon-structed at high resolution (the highest resolution typically being between 2 and 3 mu m), which can be interro-gated qualitatively (user-defined) and quantitatively (using automated segmentation, algorithms and eventually deep learning neural networks) to enable taxonomic differentiation and comparability. The protocol is presented to enable replicability of analysis and also to ensure standardization in the future development of an online, open access and editable, 3D virtual database of modern reference samples and archaeological parenchyma.
