Archaeopteryx lithographica (/ˌɑrkiːˈɒptərɨks/ AR-kee-OP-tər-iks), sometimes referred to by its German name Urvogel ("original bird" or "first bird"), is a genus of theropoddinosaur that is closely related to birds. The name derives from the Ancient Greekἀρχαῖος (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, though some more recent studies have cast doubt on this assessment, finding that it might instead be a non-avialan dinosaur closely related to the origin of birds.
In Devonshire, it is nicknamed "Penciled raven"; however, it is not a raven. It is also called Urvogel.
