More than 20 types of dinosaur tracks have been discovered in Australia, in an area described by researchers as the country’s own Jurassic Park.

Palaeontologists from the University of Queensland and James Cook University consider the tracks in 140-million-year-old rocks of the Kimberley region, Western Australia, to represent the world’s most diverse dinosaur track assemblage.

“This discovery documents non-avian dinosaurs in the western half of the continent and provides the only evidence of Australia’s dinosaur fauna from the first half of the Early Cretaceous,” said Steve Salisbury, lead author of a paper published in the Memoir of the Society of Vertebrate Paleontology. He added:

“It also provides the only confirmed evidence of stegosaurs in Australia. Some of the largest dinosaur footprints ever recorded were also found.”
