Wintonosaurus is a genus of dinosaur that lived during the Late Cretaceous period, approximately 95 million years ago. It was discovered in Australia, specifically in the Winton Formation of Queensland. This dinosaur is classified as a sauropod, which means it was a large, long-necked herbivore. The fossils of Wintonosaurus include parts of its skeleton, providing insights into its size and structure. It is believed to have been a relatively large dinosaur, reaching lengths of up to 15 meters. Its discovery has helped paleontologists understand more about the diversity of dinosaurs that roamed the ancient landscapes of Australia.
