Morphology

Jurassic = Jura (opaque) = Jura + ic

Formed from the place name 'Jura' plus the adjectival suffix '-ic', but the term denotes a specialized geological time interval and is not inferable from the place name by average learners.

Etymology

Jurassic comes from the name of the Jura mountains between France and Switzerland, where geologists studied rocks full of dinosaur fossils. So Jurassic now names the long time when dinosaurs lived.
