Koolasuchus was a amphibian that lived during the Aptian stage of the early Cretaceous. The amphibian was huge! It inhabited Southern Australia. During that time Australia was near where Antarctica is. It was discovered in 1997. This colossal amphibian swam in cold water where crocodiles never went. The crocodilians did not like the cold water.
It moved slow on land, due to its tiny arms and legs. It grew to around 4 - 5 meters. That's twice the size of a Japanese Giant Salamander! The part of its name "Cool" describes that it swam in cold water.
Like other Chigutisaurids, It had a wide rounded head with tabular horns projecting from the back part of the skull. Its skull was 65 cm long! This species survived because it could adapt to the cold water. It's eyes are on top of it's skull.
That's all for this prehistoric amphibian!
