This ancient amphibian was about 1.5 meters long and belongs to the Benthosuchidae family (a small group of giant crocodile-like amphibians that lived during the Triassic period. They lived mainly in rivers and lakes. They grew up to 2.5 meters long and have no direct relatives alive today). Photo: @Federal University of Pampa.
