Analysing a Neanderthal jaw. Researchers Christoph Zollikofer (centre, with 3-D glasses) and Marcia Ponce de Leon manipulate a fossil jawbone on computer after it has been CT (Computed Tomography) scanned. A resin cast of the jaw is being held; a skull cast is also seen. The jaw is of a Neanderthal child aged 3-4 found at Devil's Tower, Gibraltar, in 1926. This research at the Anthropologisches Institut, University of Zurich, Switzerland, enables fragments of the skull to be viewed from different angles, pieced together, and measured. The computer can also reconstruct missing fragments to build a whole skull.
