In their technical comment Salesa et al. (2011) raise several issues, including an important topic affecting most, or perhaps all, paleoecological studies-the difficulty of determining a reasonable way to deal with taxonomy. Specifically, Salesa et al. draw our attention to a taxonomic revision of Iberian Anchitherium (Sanchez et al. 1998), that we failed to follow in our study (Eronen et al. 2010), and express concerns that a different handling of Anchitherium taxonomy would have affected our results and conclusions.
