An article published in the journal “Science Advances” reports a study on Stupendemys geographicus, a giant turtle that lived in today’s South America between 5 and 10 million years ago, in the Miocene period. A team of researchers led by Dr. Marcelo Sánchez of the University of Zurich studied a number of well-preserved carapaces of this animal that provided much more information than the fossils previously available, such as the fact that the males had horns. It was one of the largest turtles ever lived with a carapace that could be up to almost 3 meters long, lived in the areas around fresh water and was probably prey to the gigantic alligators of the genus Purussaurus.
