 Scientists have confirmed for the first time that Australia was once home to a theropod dinosaur¹ that was big, fast and terrifying, not unlike the Velociraptor featured in the movie Jurassic Park.

 

It was an 1,100 pound meat-eating predator² with three slashing³ claws on each of its powerful forelimbs, and it's believed to have stalked the land that is now Australia 98 million years ago. Fossilized remnants of its limb bones, ribs⁴, jaws⁵ and fangs⁶ were found along with bones of two newly discovered species of long-neck herbivore dinosaurs⁷. Those dinosaurs each weighed up to 17 and 22 tons. Their remains⁸ have been found in Australia's state of Queensland, the first such find in nearly 30 years. The bones of all three are on display, two at the Australian Age of Dinosaurs Museum of Natural History in Winton and the third at Queensland Museum in Brisbane.

 

"The announcement of one new Australian dinosaur is world news; the announcement of three new Australian dinosaurs is out of this world."

 

The two gigantic 52-foot long plant-eating theropods were until now unknown type of titanosaur, the largest dinosaurs that ever lived. All three lived in the mid-Cretaceous period. The Cretaceous period extended from 145 million years to 65 million years ago. The discovery was analyzed⁹ in a report published in the science journal PLoS ONE, the online site of the Public Library of Science. It’s the first substantial find of large dinosaurs in Australia to be revealed in 28 years.
