means A member of a vast group of reptiles that dominated land ecosystems for over 165 million years until most went extinct, surviving today only as birds — and figuratively, anything hopelessly outdated.

from Coined in 1842 by the English anatomist Richard Owen from Greek 'deinos' (terrible, awesome) and 'sauros' (lizard) — literally 'terrible lizard.' Owen, studying the giant fossil bones turning up across England, wanted a name worthy of these monsters. The irony the science later revealed: dinosaurs weren't lizards at all, and many were closer to birds than to anything reptilian we'd recognize. The figurative 'hopelessly out-of-date' sense is a 20th-century twist, born from the popular image of dinosaurs as lumbering creatures who couldn't adapt and died out.
