STORYLINE:
The skeleton of what could be a new dinosaur species - a giant, Patagonian plant-eater - has been uncovered in Argentina.
At more than 32 metres (105 feet) long, it is among the largest ever found, scientists said on Monday.
Scientists from Argentina and Brazil said the Patagonian dinosaur appeared to represent a previously unknown species, 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.
Jorge Calvo, director of paleontology centre of National University of Comahue, Argentina, was lead author of a study on the dinosaur published in the peer-reviewed Annals of the Brazilian Academy of Sciences.
"The neck alone must have been 17 metres (56 feet) long," he said. "The tail vertebra measure 65 centimetres (28 inches). Looking at all the other vertebrae, we figured the tail probably measured 15 metres (49 feet). So, we estimate that the animal must have been 32 to 34 metres (105 to 112 feet) long."
Calvo's team began the excavation on the banks of Lake Barreales in the Argentine Patagonia in 2000.
Over seven years scientists have recovered the creature's neck, back region, hips and the first vertebra of its tail.
The project has included the participation of scientists from Argentina, Brazil and Italy.
The creature's tail vertebrae measures 65 centimetres (26 inches).
Calvo added that, besides its prodigious length, the dinosaur was also extremely tall.
He estimated that it stood over 13 metres (43 feet) tall.
The excavated spinal column alone weighed about 8 metric tons (9 tons).
Scientists said the giant herbivore would have walked the Earth some 88 (m) million years ago during the late Cretaceous period.
The site where Futalognkosaurus was found has been a bonanza for palaeontologists, yielding more than 1,000 specimens, including 240 fossil plants, 300 teeth and the remains of several other dinosaurs.
Alexander Kellner, a palaeontologist from Rio de Janeiro's National Museum and the editor of Brazilian Academy of Science's "Anais," called the area "truly unique".
"There is no other place in the world where there is such a large and diverse quantity of fossils in such small area," Kellner said.
Patagonia also was home to the other two largest dinosaur skeletons found to date - Argentinosaurus, at around 35 metres (115 feet) long, and Puertasaurus reuili, between 35 and 40 metres (115 feet to 131 feet) long.
Comparison between the three herbivores, however, is difficult because scientists have only found few vertebrae of Puertasaurus and, while the skeleton of Futalognkosaurus is fairly complete, scientists have not uncovered any bones from its limbs.
The findings were published in the most recent issue of the Annals of the Brazilian Academy of Sciences, peer-reviewed journal.
