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,
Specimens of Archaeopteryx a fish. Fragments of the braincase and upper jaw were later identified and published by other researchers. While Owen's 1863 monograph on the specimen is historically considered to be the first real description of "Archaeopteryx", Henry Woodward, assistant of the Geological Department of the British Museum, had published a shorter article on the specimen in December 1862. Here he provided a detailed description as well as the first published illustration of the specimen, sketched from the original. Rather than an attempt to steal Owen's glory, Woodward gave him due credit in this article as its official describer. Woodward's article nevertheless
