Archaeopteryx, sometimes referred to by its German name Urvogel (“original bird” or “first bird”), is a genus of early bird that is transitional between feathered dinosaurs and modern birds. The name derives from the ancient Greek ἀρχαῖος (archaīos) meaning “ancient”, and πτέρυξ (ptéryx), meaning “feather” or “wing”. Since the late 19th century, it has been generally accepted by palaeontologists, and celebrated in lay reference works, as being the oldest known bird.
