Galleonosaurus is a genus of basal ornithopod dinosaur from Australia, from the region of the Wonthaggi Formation of the Gippsland region of Victoria. The type and only species is G. dorisae, described by Herne et al. in 2019.

Discovery and naming


The name Galleonosaurus dorisae refers to the shape of the upper jaw, resembling the upturned hull of a sailing ship called a galleon, and also honours the work of Dr. Doris Seegets-Villiers, who produced her Ph.D. thesis on the palaeontology of the locality where the fossils were discovered.

Galleonosaurus was a noticably small-bodied herbivorous dinosaur within the large family called ornithopods. These small dinosaurs would have been agile runners on their powerful hind legs. 

Life restoration

Galleonosaurus is the fifth species of noticably smaller ornithopod named from Victoria, which according to Dr. Herne, "confirms that on a global scale, the diversity of these small-bodied dinosaurs had been unusually high in the ancient rift valley that once extended between the spreading continents of Australia and Antarctica." Small ornithopods do appear to have thrived on the vast forested floodplain within the ancient rift valley.  

Galleonosaurus was probably a potential prey item to animals such as the Australovenator, Australian Spinosaurid, Koolasuchus and Ozraptor.
