*** Huge Patagonian dinosaurs hunted in packs

A huge find of bones in the Patagonian desert shows the largest of
the flesh-eating dinosaurs was even more fearsome than was supposed -
the eight-ton monsters hunted in packs. Four or perhaps five of the
Cretaceous-era lords of the Patagonian plains died together 90
million years ago. A fast-flowing river swept them onto what is now a
sandy rise in the scrubby desert of Argentina's southern province of
Neuquen, where their bones fossilized in shallow earth. The bones
were dumped by a river flowing west to the Pacific since the Andes
mountains did not exist 90 million years ago. Rivers in Argentina now
flow east to the Atlantic. See
