Archaeopteryx was principally arboreal on the basis of the curvature of the claws which has since been questioned. The absence of trees does not preclude "Archaeopteryx" from an arboreal lifestyle, as several species of bird live exclusively in low shrubs. Various aspects of the morphology of "Archaeopteryx" point to either an arboreal or ground existence, including the length of its legs and the elongation in its feet; some authorities consider it likely to have been a generalist capable of feeding in both shrubs and open ground, as well as along the shores of the lagoon. It most likely hunted small prey,

"Urschwinge" was the favored translation of "Archaeopteryx" among German scholars in the late 19th century. In English, "ancient pinion" offers a rough approximation. Hermann von Meyer learned of the discovery of what would later be known as the London Specimen before he published his analysis of the single "Archaeopteryx" feather. In September 1861 he wrote to the "Neues Jahrbuch" about being informed of the discovery by Friedrich Ernst
