Morphology

pre-Jurassic = Jurassic (transparent) = pre + Jurassic

The prefix 'pre-' straightforwardly means 'before', so a learner who knows 'Jurassic' can readily infer 'before the Jurassic period'.

Etymology

Pre-Jurassic combines pre- meaning 'before', as in preheat, and Jurassic, the name for the age of many dinosaurs that comes from the Jura mountains, so it means the time 'before' the Jurassic period.
