Mapusaurus roseae

New Scientist Breaking News - Giant dino-predators may have hunted in packs

Giant predatory dinosaurs may have hunted in packs to bring down the biggest plant-eating prey.

The evidence comes from the first detailed analysis of the remains of giant predatory dinosaurs uncovered in Patagonia over a span of five years, starting in 1997. The 100-million-year-old bones come from a previously unknown species closely related to Giganotosaurus, a huge and slightly older creature also unearthed in Argentina (see “The dino-daddy of all meat eaters”).

The discoverer, Rodolfo Coria of Museo Carmen Funes in Neuquen, Argentina, has named the new species Mapusaurus roseae.

Cool.
