Galleonosaurus is known from five upper jaw bones (maxillae), and the holotype is the most complete dinosaur upper jaw ever found in Victoria, Australia.1
Scientists used micro-CT scans to see the inside of its jaw, revealing a complex network of nerves and blood vessels.1
It lived between about 125 and 110 million years ago, during the Barremian to Albian ages of the Early Cretaceous.6
Galleonosaurus belonged to a group of dinosaurs called Elasmaria, which were only found on the southern supercontinent Gondwana.61
Its fossils were found in rocks that were once part of a large river system with floodplains, where Galleonosaurus likely roamed.1
The name Galleonosaurus means 'galleon lizard', inspired by the shape of its upper jaw bone that resembles a sailing ship.1
