Non-invasive Archaeology of Skeletal Material by CT Scanning and Three-dimensional Reconstruction

The remains of an ancient Sumerian skeleton, approximately 7000 years old, were investigated using the techniques of stereolithography. The very fragile and delicate skeletal material was recovered in a block, thus retaining it in the soil matrix. The excavated block was CT-scanned and the skeletal material was rendered in three dimensions. This formed the basis for a stereolithographic model of the mandible, which was used for physical and dental anthropological studies. Skeletal remains may thus be made available for research without having to remove them from the local matrix, which may be an advantage in an archaeological or palaeoanthropological setting. © 1997 by John Wiley & Sons, Ltd.
