According to a press release from the University of Queensland, a team of researchers analyzed dinosaur footprint fossils and concluded they belonged to carnivorous dinosaurs with large bodies up to three meters tall at the hips and about 10 meters long. “To put it in perspective, the tyrannosaur rex reached 3.25 meters on the hips and reached lengths of 12-13 meters but it did not appear until 90 million years after our Queensland giants,” the lead researcher said. Anthony Romilio, collegiate paleontologist.
“The footprints from Queensland were probably made by giant carnosaurs, the group which includes allosaurs. Those were likely some of the planet ‘s largest predatory dinosaurs at the time, “he added. The footprints, which date back to the late Jurassic period, between 165 and 151 million years ago, were mostly between 50 and 60 centimeters in length, Romilio said, and some reached almost 80 centimeters.
“These footprints were made by dinosaurs wandering through the swampy forests that once dominated most of the southern Queensland landscape today,” he explained. Romilio notes that paleontologists in North America had previously known about tyrannosaurus rex, giganotosaurus in South America, and spinosaurus in Africa, but now there is evidence that Australia has large carnivorous dinosaurs.
