Meet the “Galleonosaurus dorisae”, or Galleonosaurus for brief. It is 125 million years previous and as soon as bopped about Victoria, southeastern Australia on its hind legs throughout the Cretaceous. Within the frequent parlance of stereotypical Australians that do not truly exist, you would possibly name her a “little ripper”.
It’s thought to have been the dimensions of probably the most Australian of animals: the wallaby.
The Galleonosaurus was a small herbivorous creature from the ornithopod household, however it knew the right way to transfer.
“These small dinosaurs would have been agile runners on their highly effective hind legs,” stated Dr Matthew Herne, a vertebrate palaeontologist from the College of New England in Armidale, New South Wales.
Ornithopods have been among the many most profitable herbivores within the Cretaceous interval, beginning out as small bipedal grazers however ultimately bought as large because the Edmontosaurus, which may develop to as much as 50 ft (15 metres) lengthy.
The Galleonosaurus, nonetheless, was a lot smaller, and named for its higher jaw, which resembles a ship (or a galleon). It is the fifth small ornithopod genus named from Victoria in Australia. Herne says this “confirms that on a world scale, the range of those small-bodied dinosaurs had been unusually excessive within the historical rift valley that when prolonged between the spreading continents of Australia and Antarctica.”
The Galleonosaurus was discovered by volunteers at Dinosaur Dreaming, a joint challenge run by Monash College and Museum Victoria. The outcomes have been revealed within the Journal of Paleontology.
