A workforce of researchers analyzed dinosaur footprint fossils and concluded they belonged to large-bodied carnivorous dinosaurs that have been as much as three meters excessive on the hips and about 10 meters lengthy, in response to a press launch from the College of Queensland.
“To place that into perspective, T. rex received to about 3.25 metres on the hips and attained lengths of 12 to 13 metres lengthy, but it surely did not seem till 90 million years after our Queensland giants,” stated lead researcher Anthony Romilio, a paleontologist on the college.
“The Queensland tracks have been most likely made by big carnosaurs — the group that features the Allosaurus. On the time, these have been most likely among the largest predatory dinosaurs on the planet.”
The footprints, which date from the late Jurassic interval, between 165 and 151 million years in the past, have been principally between 50 and 60 centimeters in size, stated Romilio, with some reaching nearly 80 centimeters.
“These tracks have been made by dinosaurs strolling by way of the swamp-forests that after occupied a lot of the panorama of what’s now southern Queensland,” he stated.
Romilio factors out that paleontologists beforehand knew in regards to the Tyrannosaurus rex in North America, the Giganotosaurus in South America and the Spinosaurus in Africa, however now there’s proof Australia had massive carnivorous dinosaurs.
Whereas that is the primary time the fossils have been scientifically described, they have been found greater than half a century in the past, stated Romilio.
“They have been found within the ceilings of underground coal mines from Rosewood close to Ipswich, and Oakey simply north of Toowoomba, again within the 1950s and 1960s,” he stated, explaining that they’d sat in museum drawers for many years.
The complete analysis paper was printed within the journal Historic Biology.
In 2017 researchers discovered the world’s greatest dinosaur footprint in northwestern Australia.
Measuring almost 5 ft 9 inches (1.75 meters), the monitor belonged to a sauropod, a long-necked herbivore.
The file was beforehand held by a 1.15 meter-long (almost Three ft 9 inches) footprint present in Bolivia in July 2016, which was the largest ever from a carnivorous dinosaur.
