酷東西

趣味知識

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.6 1

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

發現: Galleonosaurus was named in 2019 by paleontologist Matthew Herne and colleagues, based on fossils collected from the Flat Rocks site in Victoria, Australia. The species name dorisae honors Doris, a volunteer who helped with fossil hunting.1
仍有爭議: Scientists are not sure exactly how big Galleonosaurus was, because only jaw bones have been found so far.1
