This is an ABSTRACT ONLY. The definitive version is published in Spectrochimica Acta Part B: Atomic Spectroscopy, vol. 73, pp 48- 54Laser Induced Breakdown Spectroscopy (LIBS) was used to study the spectra from fossils and surrounding rock recovered from the Cradle of Mankind site at Malapa, South Africa. The objective was to find a suitable spectral line(s), specific to fossils, which could be used as a control signal to limit damage to fossils during high speed laser removal of the encasing rock. The calcified clastic matrix (rock) encasing the fossils was found to emit a variety of complex LIBS spectra. Nevertheless, it was found possible to distinguish fossils in a single LIBS pulse, and without significant damage to the fossil, using spectral lines of neutral phosphorus.enLaser Induced Breakdown SpectroscopyLIBSFossilsCradle of MankindLaser fossil preparationLaser spectroscopyLaser processingArticleRoberts, D., Du Plessis, A., Steyn, J., Botha, L., Pityana, S.
