/ˈtɛrəˌsɔr/

Origin: Formed within English, by compounding; modelled on a Latin lexical item. Etymons: ptero- comb. form, -saur comb. form.

Etymology: < ptero- comb. form + -saur comb. form, after scientific Latin Pterosaurus, genus name ( L. J. F. J. Fitzinger Systema reptilium (1843) 15). Compare French ptérosaure (1875). Compare slightly earlier pterosaurian n.

Palaeontology.

Any of numerous extinct flying reptiles of the Mesozoic order Pterosauria, which had the fourth digit of each forelimb prolonged to a great length to support a wing membrane for active flight. Cf. pterodactyl n.
