Austrosaurus

Austrosaurus (meaning "Southern lizard") is a genus of sauropod dinosaur from the Allaru Formation and Winton Formation, from the early Cretaceous (110-105 million years ago) of Central-Western Queensland in Australia. Originally it was thought that sauropods spent time near or in water to relieve weight from their legs.[1] However, this theory is now rejected and it is believed that Austrosaurus like all sauropods lived on dry land. Fossil finds suggest a height of approximately 3.9 metres at the hip and 4.1 metres at the shoulder, which would have given it an almost level back. According to Gregory S. Paul, it was 20 meters long and weighed about 16, 000 kg.[2]
