Morphology

argentinosaur = Argentina (semi-transparent) = Argentina + saur

The link to 'Argentina' is clear, but the combining form 'saur' (meaning 'lizard') is a specialized Greek element that some learners may not recognize.

Etymology

Argentinosaur comes from Argentina and the Greek root sauros meaning 'lizard'. So it literally means 'Argentina lizard' and helps you remember it was a huge plant-eating dinosaur found in Argentina.
