Bonaparte & Coria, 1993
Argentinosaurus meaning "Argentina lizard", was named by paleontologists Coria & José Bonaparte in 1993. It is known from fossilized back vertebrae, tibia, ribs and sacrum. It may be the largest dinosaur, but its remains are so imcomplete that palaeontologists prefer to use Saltasaurus for their calculations.
