Publisher's Note: Correction to Author contribution

Posted by u_lombardo on 30 Aug 2013 at 11:29 GMT

Because of an error, in the section "Author contribution" the sentence "Performed faunal remains analysis: RH KS" is missing. The correct reading of the "Author contribution" section should be:
Conceived and designed the experiments: UL. Wrote the paper: UL KS JMC JM. Did the field work: UL JMC JM AP HV. Performed steroid and BC analysis: WA EL. Performed faunal remains analysis: RH KS. Performed LoI, XRD and thin sections analysis: UL. Secured funding: HV. Discussed the results and reviewed the text: UL KS JMC JM WA RH EL AP HV.
