The discovery could help redraw the world map during the dinosaur era, researchers add.

That's because the newfound Australian dinosaur shows that animals could travel across the prehistoric supercontinent of Gondwana during the Cretaceous period, about 145 to 65 million years ago.

In an exclusive American Scientist interview, Arthur Kosowsky—a member of the ATC team and a professor in the Department of Physics and Astronomy at the University of Pittsburgh—discusses how he is using ATC to reach back in time billions of years to search for gravitational waves that could verify inflation and reveal unprecedented details about how the cosmos was born.
