We recently published a correction (BMJ 2011;342:d539, doi:10.1136/bmj.d539) to this article by Philippe Charlier and colleagues (BMJ 2010;341:c6805, doi:10.1136/bmj.c6805) as we had been alerted by one of the authors that her name had been submitted to us with the wrong spelling and missing her middle initial. Her name is Paula F Campos (not Paola Campos, as was published in the article). There are several authors of this article with the initials PC or PFC, and this makes the published Contributors section ambiguous in this respect. Unfortunately, in the recent correction, we tried to clarify the role of Paula F Campos and got it wrong. Here are the contributions of the authors whose initials are (or were) either PC or PFC: Philippe Charlier conceived and headed the project and did the anthropological and paleopathological analyses and the microscopic and endoscopic examinations. Pierre F Chaillot did cranial measurements from computed tomography reconstructions. Paula F Campos did ancient DNA extractions and analyses. Philippe Charlier wrote most of the manuscript.
