Cuvier, Georges Léopold Chrétien Frédéric Dagobert, Baron(zhôrzh lāôpôld` krātyăN` frādārēk` dägôbĕr` bärôN` küvyā`), 1769–1832, French naturalist, b. Montbéliard, studied at the academy of Stuttgart. From 1795 he taught in the Jardin des Plantes. He became permanent secretary (1803) of the Academy of Sciences and later was made chancellor of the Univ. of Paris. A pioneer in the science of comparative anatomy, he originated a system of zoological classification that comprised four phyla based on differences in structure of the skeleton and organs, and recognized that extinction of animal species had occurred in geologic history. His reconstruction of the soft parts of fossils deduced from their skeletal remains greatly advanced the science of paleontology. The flying reptile pterodactyl (see pterosaurpterosaur
[Gr., = winged lizard], extinct flying reptile (commonly called pterodactyl [Gr., = wing finger]) of the order Pterosauria, common in the late Triassic and Cretaceous periods, from approximately 228 to 65 million years ago.
