Several dinosaur theropod bones were found in the Eumeralla geological formation near Victoria, Australia, whose layers date back to the early Cretaceous period. According to a communiqué from Swinburn University of Technology and Victoria’s museums, there is also a 20 cm long claw of the upper leg among the remains.
Theropods are a group of dinosaurs that includes the famous Tyrannosaurus predators and Velociraptor are considered to be the direct relatives of modern birds. Remains dating back 107 million years ago were discovered between 2011 and 2017 by a group of volunteers who worked at a site known as “Eric the Red West” on the Athvea coast. Thanks to the remains found at this site, a collector of a diluvior, a dinosaur ornithologically similar to that of the dinosaur classified in 2018, has already been classified in the past.
The new remains were found in relatively isolated areas and should not belong to any of the skeletons. The same remains were eventually transported over time by the ancient, once deep, fast flowing rivers that were in the fracture of the valley, now called the Bass Strait, which formed when Tasmania and Australia split 110 million years ago.
Paleontologists believe that the bones found here belong to a group of terpods called megaraptorides, which are very similar to the Australian vintonensis terpods that lived several million years later, during the Late Cretaceous period (about 95 million years ago), the remains of which were found thousands of miles north.
This suggests that megaraptoric terpods were present in large parts of Australia and that they had previously paid or migrated to the continent.
According to Stephen Poropath, a Swinburn researcher who conducted research that led to the discovery of these remains, the similarities between the same remains and the Australian covenant are “surprising”: “If we had found these tenopod bones in Queensland, we would probably call them Australian vintonnis. But they’re from Victoria, which begs the question: can there be something like a dinosaur for more than ten million years, through Eastern Australia? Maybe.”
The study was published in the Journal of Paleontology of Vertebrates.
