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.
"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. He was lead author of a study on the dinosaur published in the peer-reviewed Annals of the Brazilian Academy of Sciences. Other Top Headlines Photos
Calvo said the neck alone must have been 56 feet long, and by studying the vertebrae, they figured the tail probably measured 49 feet. The dinosaur reached over 43 feet tall, and the excavated spinal column weighed about 9 tons when excavated. One neck vertebra alone measured more than 3 feet high.
