Morphology

Argentinosaurus = Argentina (semi-transparent) = Argentina + saurus

The name is motivated by Argentina plus the taxonomic suffix -saurus ('lizard'), but the scientific formation is specialized and not fully predictable for most learners.

Etymology

Argentinosaurus comes from Argentina and the Greek part -saurus, which means 'lizard' and also appears in dinosaur. So Argentinosaurus means 'Argentina lizard', a simple name to remember that it is a very large dinosaur found in Argentina.
