Estudio bibliométrico de género en la paleontología de vertebrados. El caso de la revista argentina Ameghiniana (1957-2011)

The objective of this work is to assess gender distribution differences in authorship of papers in the field of vertebrate paleontology published in the Argentine journal Ameghiniana from 1957 to 2011. The bibliometric method was used to analyze gender distribution and evolution of the signing authors, their productivity,geographical origin, authorship composition (i.e., author and co-author), order of authors, taxon and citation levels. Results show predominance of men in number of signatures, mean annual productivity rates and average citation levels. No significant differences were found between gender for the taxa studied or in the order of the signatures. Significant differences were observed in the geographical origin of the authors. In view of the authorship gender distribution of papers published in Ameghiniana, we conclude that men continue to lead in the discipline of vertebrate palaeontology. The increase of women authors, the levelling of productivity over the last decade and the increase co-authorships including women, however, are clear signs of a shifting trend
