Diamantinasaurus and Wintonotitan are the first new sauropods to be named in Australia in over 75 years, the most recent being Austrosaurus in 1933.

Sauropods (meaning lizard-footed) are large, four-legged, herbivorous dinosaurs and diamantinasaurus is the best preserved sauropod skeleton so far found in Australia.

This plant-eating, four-legged sauropod is a new type of titanosaur. Titanosaurs were the largest animals ever to walk the earth.

Matilda was a solid and robust animal, probably akin to a gigantic hippopotamus and is estimated to be approximately 15 to 16 metres long, 2.5 metres high at the hip and weighed approximately 15 to 20 tonnes.

Estimated to have lived 100-98 million years ago in the Mid-Cretaceous (Latest Albian) period.

The Australian Age of Dinosaurs Museum of Natural History in Winton is custodian of the Matilda fossils.
