About the Journal

Ameghiniana is a bimonthly peer-reviewed journal that publishes original contributions to all disciplines related to Paleontology, with a special focus on the paleontology of Gondwana and the biotic history of the Southern Hemisphere. Published yearly since 1957, it has become one of the main paleontological publications from Latin America. Ameghiniana has recently broadened its editorial team, reorganized its production process, and increased its frequency to a bimonthly frequency, resulting in a significant decrease in the turnaround time.
