Koolasuchus is the last of a dieing species of large Amphibeans. It lived in Australia during the Early Cretaceous. It lived the swamps, it acted like a crocodile but unlike crocodiles this anphibeans small legs compared to its body. So it will have to drag its body slowly when leaving the water. It moves very slow on land than in the water. But once in the water it is able to take down smaller prey that come close to the water. During Winter it hibernates under a pile of mud.
