The feasibility of laser-ablation based analytical methods for quantitative and qualitative microspatial analysis of different samples has been reported by several authors . In particular, Laser Induced Breakdown Spectroscopy (LIBS) and Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) allow fast multielemental analysis in a broad variety of matrices. Furthermore, the excellent spatial resolution of these methods offers the possibility to study the chemical distribution, namely chemical mapping, of the elements constituents2. Additionally, LA-ICP-MS provides high sensitivity and low detection limits. Here the feasibility of LIBS and LA-ICP-MS for microspatial analyses of a fossil snake vertebra will be discussed. The microchemical analysis is coupled to the synchrotron radiation hard-X ray microtomography measurements The feasibility of laser-ablation based analytical methods for quantitative and qualitative microspatial analysis of different samples has been reported by several authors .
