New Mid-Cretaceous (latest Albian) dinosaurs fromWinton, Queensland, Australia.

<h4>Background</h4>Australia's dinosaurian fossil record is exceptionally poor compared to that of other similar-sized continents. Most taxa are known from fragmentary isolated remains with uncertain taxonomic and phylogenetic placement. A better understanding of the Australian dino...
