Anisopleurodontis - a shark-like fish from the Permian period, related to the famous Helicoprion. Found in the same fossil formation as Prionosuchus, it lived in rivers, lakes or maybe even swamps in Brazil ~270 million years ago, being the second-largest predator there. 1/3
@gabipaleo.bsky.socialPrionosuchus - a massive crocodile-like amphibian from the Permian period (~270 million years ago), lived in what is now Brazil. Reaching up to 9 meters, it was possibly the largest, or at least the longest, amphibian ever known, dominating Permian swamps, rivers, and lakes. 1/3
