New Dinosaur May Link S. American, Aussie Dinos
A rare fossil found in Australia suggests dinosaurs were able to trek north across a vast continent, scientists report.
The hundred-million-year-old fossil belonged to a two-legged meat-eater, or theropod, that is closely related to Megaraptor namunhuaiquii, a giant, big-clawed carnivore from Argentina, says a team led by Nathan Smith of the University of Chicago's Field Museum. 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. This in turn suggests that Gondwana's Southern Hemisphere landmasses broke up later than traditionally thought.

VIDEO: The Promise and Peril of Drones
The automation of tasks at work and at home is just around the corner, including driving cars, piloting planes, delivering packages, and transporting weapons. Unmanned aerial vehicles are rapidly evolving to meet both society’s and the military’s needs in automation and better efficiency.
During her time as one of the first female fighter pilots in the US Navy, Dr. Missy Cummings observed that computers could take off and land a plane more precisely than humans. Because of this breakthrough and her fascination with this growing technology, she began human–drone interaction research.
