A petite, dexterous dinosaur with incredibly strong hind legs wandered the prehistoric rift valley in between Australia and Antarctica during the Cretaceous time frame.
As of late, archaeologists found fossils from this species – estimated to be the size of a wallaby – while uncovering 125-million-year-old rocks in Victoria, Australia. They discovered five fossilized upper jaws that appeared like the upside-down frames of ships known as galleons.
Galleonosaurus dorisae was the name the scientists gave the unique species, after both the galleon and scientist-paleontologist Doris Seegets-Villiers, who earned her doctorate while working in the region. Survey of the bones demonstrated that the freshly discovered dinosaur species was an ornithopod, a group of plant-eating dinosaurs that had feet that resembled that of birds and strolled on their hind legs.
The bones were covered in volcanic residues that were probably carried in by streams that flowed from an active eastern volcanic range amid the Cretaceous time frame. “The residues washed by waterways into the valley made a forested stream floodplain whereupon dinosaurs, for example, Galleonosaurus and numerous different kinds of dinosaurs and different creatures prospered,” lead study author Matthew Herne, a postdoctoral individual at the University of New England disclosed to the Live Science.
Simply a year ago, the same team discovered a new ornithopod species from these volcanic residues: Diluvicursor pickeringi. Their examination proposes that G. dorisae is an extremely close relative of D. pickeringi, however, older by at least 12 million years.
They likewise discovered that this freshly discovered species was more firmly related to ornithopods from Patagonia than those from North America and China.
The survey proposes, “Terrestrial bridges in between Australia and South America, through Antarctica, more likely have been available to dinosaur species now and again amid the Cretaceous that brought about nearer hereditary connections between the dinosaurs on these landmasses than between these dinosaurs and those in other spots,” he composed.
The G. dorisae fossils were found 10 years or so prior by volunteers associated with Project Dinosaur Dreaming, who were unearthing near the towns of Inverloch and Wonthaggi, as per the statement. However, it wasn’t until long ago that the researchers considered and portrayed the species.
The discoveries were published in the Journal of Paleontology on Monday.
