Specimens of Archaeopteryx the results of his investigation was a talk at the Royal Society in London in November, and was published as an abstract in the Proceedings of the Royal Society the following year. Here he considered the single feather described by von Meyer in 1861 and assigned the new skeleton the same genus. Owen speculated possible short- and long-tailed forms of "Archaeopteryx" and on these grounds assigned the London specimen the species name "macrura", meaning "long-tailed". Owen, who published a monograph on the specimen in 1863, generally considered the animal to be a bird despite describing its structure and proportions as

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
