A team of researchers analyzed the dinosaur fingerprint fossils and concluded that they belonged to large-carnivorous dinosaurs that were three meters high at the hips and about 10 meters high, according to a press release from the University of Queensland.
“To take this into account, Trek Rex reached about 3.25 meters at the hips and achieved lengths ranging from 12 to 13 meters, but it didn’t appear until 90 million years after the Queensland giants,” said lead researcher Anthony Romelio. The paleontologist at the university.
“Queensland paths may have been made by giant carnosaurs – the group that includes allosaurus. At that time, these were perhaps some of the largest predatory dinosaurs on the planet.”
Romelio said that footprints, dating from the late Jurassic period, between 165 and 151 million years ago, were mostly between 50 and 60 cm, some of which amounted to approximately 80 cm.
“These paths have made dinosaurs walk in the swamp forests that once occupied a large portion of the landscape of what is now southern Queensland,” he said.
Romelio notes that paleontologists previously knew about Tyrannosaurus rex in North America, Giganotosaurus in South America and Spinosaurus in Africa, but there is now evidence that Australia has large carnivorous dinosaurs.
While this is the first time that fossils have been scientifically described, they were discovered more than half a century ago, Romelio said.
“They were discovered in the underground coal mine roofs of Rosewood near Ipswich and OKI just north of Toowoomba in the 1950s and 1960s,” he said, explaining that they had been sitting in the museum’s stairs for decades.
The full research paper was published in the Journal of Historical Biology.
In 2017, researchers found the world’s largest dinosaur fingerprint in northwest Australia.
The track, which is about 5 feet 9 inches (1.75 meters) long, belongs to Sauropaud, a long-necked grass.
The record was previously recorded with a fingerprint of 1.15 meters (about 3 feet and 9 inches) found in Bolivia in July 2016, which was the largest ever of a carnivorous dinosaur.
