Tiny tyrannosaurs rewrite evolutionary rules
Looming larger than a double-decker bus and baring teeth that have been likened to serrated bananas, Tyrannosaurus rex has long been considered one of the most fearsome creatures ever to have walked the earth. Other familiar tyrannosaurs, such as Albertosaurus and Tarbosaurus , were likewise terrifying in their size and bite--despite those absurd-looking but characteristic arms. But it turns out that not all tyrannosaurs have these hallmark features.This past fall paleontologists unveiled two tyrannosaurs new to science that are shaking up long-standing ideas about everyone’s favorite mega-predator. The finds are forcing researchers to reevaluate the origin of the tyrannosaur body plan and reconsider what they thought they knew about the diversity of this well-studied group. “Our view of tyrannosaur evolution has changed dramatically,” says doctoral student Stephen L. Brusatte of the American Museum of Natural History in New York City. [More] rss.sciam.com |

The crocodile got loose, the crew and passengers panicked, and the plane crashed, killing 20 people.Oddly enough, the crocodile survived the crash, only to be hacked to death by machete-wielding locals on the ground.
