Researchers have found in a new study that giant carnivorous dinosaurs could also be found in Australia. This is evidenced by the fossil footprints of dinosaurs found in the southern Australian state of Queensland. The footprints date from the last period of the Jurassic and are immortalized in the mud between 165 and 151 million years ago. “These tracks were made by dinosaurs that walked through the swamp forests,” paleontologist Anthony Romilio explains. This landscape was once a big part of today’s southern part of Queensland.”
After a thorough analysis of the footprints, it appears that these belonged to a huge dinosaur. “Most prints are about 50 to 60 centimeters long,” romilio says. “But there are also traces of almost 80 centimeters between them.” According to the researchers, this is clear evidence that the footprints were not left by a bird. “We think the spores were pushed into the earth by a carnivorous dinosaur with a large body,” romilio said. “Probably because of a giant Carnosauria: the group to which the Allosaurus also belongs. Back then, these were some of the largest predatory dinosaurs in the world.”
So these dinosaurs were able to reach enormous lengths. “Some had a hip height of up to three meters and could grow ten meters long.” To put this in perspective, the famous T.rex had a hip height of about 3.25 meters and reached lengths of up to twelve to thirteen meters. However, the newly discovered dino in Australia is a bit older. It turns out that the T.rex only appeared on stage about 90 million years later than the Giants of Queensland.
The discovery of the new species through footprints is quite striking. Normally, researchers look at fossilized bones that are normally housed in museums. But in this case, traces left behind millions of years ago revealed the discovery. Moreover, these fossilized prints have not been found recently. “The tracks have been known for more than half a century,” romilio said. “They were found in underground coal mines just north of Toowoomba in the 1950s and 1960s. Most were not scientifically described and have been dusting in museum drawers for decades.”
The study provides new and important insights into Australia’s natural heritage. Because now it turns out that even on this continent large and dangerous dinosaurs stomped around that left their traces in the ground. A few years ago, a research team also came across a collection of dinosaur tracks. At the time, five different types of traces of predatory dinosaurs, at least six types of traces of herbivorous dinosaurs with long necks, four types of traces of two-legged herbivorous Ornithopoda and six types of traces of dinosaurs with shields were discovered.
