Archaeopteryx Archaeopteryx Archaeopteryx (), meaning "old wing" (sometimes referred to by its German name ("original bird" or "first bird")), is a genus of bird-like dinosaurs that is transitional between non-avian feathered dinosaurs and modern birds. The name derives from the ancient Greek ("archaīos") meaning "ancient", and ("ptéryx"), meaning "feather" or "wing". Between the late nineteenth century and the early twenty-first century, "Archaeopteryx" had been generally accepted by palaeontologists and popular reference books as the oldest known bird (member of the group Avialae). Older potential avialans have since been identified, including "Anchiornis", "Xiaotingia", and "Aurornis". "Archaeopteryx" lived in the Late Jurassic around
Archaeopteryx in similar feathers"). In German, this ambiguity is resolved by the term "Schwinge" which does not necessarily mean a wing used for flying. "Urschwinge" was the favoured translation of "Archaeopteryx" among German scholars in the late nineteenth century. In English, "ancient pinion" offers a rough approximation. Since then twelve specimens have been recovered: The Berlin Specimen (HMN 1880/81) was discovered in 1874 or 1875 on the Blumenberg near Eichstätt, Germany, by farmer Jakob Niemeyer. He sold this precious fossil for the money to buy a cow in 1876, to innkeeper Johann Dörr, who again sold it to Ernst Otto Häberlein,
