Argentinosaurus was a titanosaurid sauropod dinosaur. It was an enormous, long-necked, long-tailed, quadrupedal, plant-eater from Argentina, South America during the Cretaceous period.
Argentinosaurus meaning "Argentina lizard", was named by paleontologists Coria & José Bonaparte in 1993. It is known from fossilized back vertebrae, tibia, ribs and sacrum, found in Neuquén Province. It may be the largest dinosaur,[1] but its remains are so incomplete that palaeontologists prefer to use Saltasaurus for their calculations. An accurate estimate was got for the much more complete sub-adult Dreadnoughtus.[2][3]
