Abstract

We have considered the additional data that Domínguez-Villar (this issue) has provided, as well as his criticisms of the interpretations of Martín-Chivelet et al. (2011). We argue that with or without the additional data, our original interpretations are the most likely interpretations, on the basis of Ockham's Razor. Those of Domínguez-Villar violate Ockham's Razor, and in the final analysis do not offer an alternative explanation for the Martín-Chivelet et al. (2011) and Domínguez-Villar (this issue) data. In particular, all of the 230Th ages (reported by both Martín-Chivelet et al. (2011) and Domínguez-Villar (this issue)) are in stratigraphic order, within quoted errors, so that our original chronology is robust, with no reason to invoke diagenetic processes. Given this chronology, the empirical relationship between δ13C and temperature also hold. Finally, our original mechanism for the cause of this relationship (prior calcite precipitation) has been invoked in a number of other studies to explain carbon isotopic variations and remains a perfectly plausible explanation for the observations at the studied caves.
