Plesiosaurus singular

Morphology

Plesiosaurus = plesiosaur (semi-transparent) = plesio + saur + us

The Latinized suffix '-us' is a formal genus ending and does not change the basic meaning, but it is not semantically productive for most learners.

Etymology

Plesiosaurus comes from the Greek parts plesio- meaning 'near' and -saurus meaning 'lizard'. So Plesiosaurus is the name for a long-necked sea 'lizard' — an extinct marine reptile with paddle-like limbs.
