| Abstract: | Here we respond to the comment by Nowell and Horstwood (2009) written in response to our 2008 paper where we presented the first results of the application of laser ablation strontium isotope analysis to a fossil hominin. Although we are pleased that the paper has attracted so much interest, including from researchers outside the field such as Nowell and Horstwood, we completely disagree with the two main arguments of their comment. Namely, we reject the notion that they can recalibrate our data using different methods and (non matrix-matched) standards determined in a different laboratory, and that is simply irresponsible to advocate the further development of this method for rare and important hominin samples through drilling rather than the almost non-destructive method of laser ablation that we presented in our paper. |
