Numbers of the latter group have nearly halved as our population doubled in size over the past 35 years. Ecologists, zoologists and other scientists believe that, without urgent steps to stem the losses, we are facing global...

NEW YORK - The United States returned to Mongolia more than 18 dinosaur skeletons and fossils stolen from the Gobi desert and smuggled abroad, saying they were enough to stock a museum. The haul includes skeletons of two Tyrannosaurus bataars, a cousin of the fearsome Tyrannosaurus rex, and two Oviraptors, known at least apocryphally for eating other dinosaur eggs.

Some were illegally smuggled into the US using false customs papers and others were voluntarily forfeited by a British collector to the United States for return to...

The dino was tall, measured 11.5 feet long, weighed 500 pounds and had very sharp claws. RELATED: Dinosaur Feathers Found in Amber "It was a giant raptor, but with a chicken-like head and presumably feathers," co-author Emma Schachner of the University of Utah, said in a press release. "The animal stood about 10 feet tall, so it would be scary as well as absurd to encounter." Lead author Matt Lamanna of the Carnegie Museum of Natural History...
