Morphology

ankylosaur = ankylos + saur

Formed from Greek combining stems (ankylos- + -saur) that are not productive standalone English words; an average B1 learner cannot derive the meaning from these parts.

Etymology

Ankylosaur comes from two parts: ankyl- meaning 'fused' or 'joined' and -saur meaning 'lizard', the same -saur you see in dinosaur. So an ankylosaur is like a 'fused lizard' with heavy armour plates and a club tail, which explains its meaning as a heavily armoured dinosaur.
