2022 $1 Australian Dinosaurs Diamantinasaurus PNC

Diamantinasaurus matildae was a titanosaurian sauropod (meaning lizard-footed). It lived during the Mid-Cretaceous Period, around 100-95 million years ago, in what is now southern central Queensland. This huge, four-legged, long-necked, plant-eating dinosaur is estimated to have measured 16 to 20 metres in length and about two-and-a-half to three metres high at the hip. The first fossilised bones were found in 2005 near Winton, Queensland.
