5m Long

Australia 

Middle Cretaceous (110-100 MYA)

Carnivore

Amphibian

'''Koolasuchus was a gigantic amphibian that lived more like a crocodile than that of a newt or frog for they would live in large rivers or lakes to hunt down prey like fish or turtles or even smaller dinosaurs if they can grab a hold of them and drag them into the water. These animals would have hibernated during the cold times of the Australian winter which in those days was closer to antartica than it is now, in underground burrows and filled with dry leaves that wouldn't freeze so easily during the winter when hibernating. This amphibian may have ventured into the large freshwater locations just to find mates or to find large enough food sources so that it can survive through tough hibernation's. The home that they would live in would be very lush thick forests serving as great protection of when they would move out of their hibernation burrows to go to the nearest river or lake.'''

'''These animals may have wound up extinct due to the fact that the winters grew less and less and so summers would have lasted longer though with extended summers trees would die creating larger landscapes. Plus the rivers and lakes would as well dry up creating less habitat for it to live in and because when they are out of water they could go as fast as a tortoise due to their small legs compared with their large bodies given more than enough time for predators to take them down as easy prey.'''
