摘要：

Laser removal of rock from around a fossil using 3D data was demonstrated was the first time. This proof of concept combines the power of two technologies: X-ray micro-computed tomography scanning and programmable scanning laser ablation. This simple demonstration holds promise for the semi-automated and entirely safe laser removal of bulk material from around precious fossils. (C) 2013 Elsevier Ltd. All rights reserved.
