RIO DE JANEIRO, Brazil - The skeleton of what is believed to be a new dinosaur species - a 105-foot plant-eater that is among the largest dinosaurs ever found - has been uncovered in Argentina, scientists said Monday.

Scientists from Argentina and Brazil said the Patagonian dinosaur appears to represent a previously unknown species of Titanosaur because of the unique structure of its neck.

They named it Futalognkosaurus dukei after the Mapuche Indian words for 'giant' and 'chief,' and for Duke Energy Argentina, which helped fund the skeleton's excavation.

'This is one of the biggest in the world and one of the most complete of these giants that exist,' said Jorge Calvo, director of the paleontology center at the National University of Comahue, Argentina.

Calvo was lead author of a study on the dinosaur published in the peer-reviewed Annals of the Brazilian Academy of Sciences.

Scientists said the giant herbivore walked the Earth some 88 million years ago, during the late Cretaceous period.

'I'm pretty certain it's a new species,' agreed Peter Mackovicky, associate curator for dinosaurs at Chicago's Field Museum, who was not involved with the discovery. 'I've seen some of the remains of Futalognkosaurus and it is truly gigantic.'
