Specimens of Archaeopteryx precipitated the first surge of widespread knowledge of the specimen across Europe. In the subsequent years of the 19th century, the London specimen was subject to a number of analyses by other researchers of historical importance, including Thomas Huxley, Othniel Charles Marsh, Wilhelm Dames, and Bronislav Petronievics. Much of this early study was relevant to controversy surrounding the possible taxonomic divisions of "Archaeopteryx" specimens. The London specimen is of obvious special importance because it was the first "Archaeopteryx" skeleton discovered. By coining the name "Archaeopteryx", meaning "ancient wing", von Meyer had declared the animal to be a bird. Despite the
Archaeopteryx be black throughout, with heavier pigmentation in the distal tip. The feather studied was most probably a dorsal covert, which would have partly covered the primary feathers on the wings. The study does not mean that "Archaeopteryx" was entirely black, but suggests that it had some black colouration which included the coverts. Carney pointed out that this is consistent with what we know of modern flight characteristics, in that black melanosomes have structural properties that strengthen feathers for flight. In a 2013 study published in the "Journal of Analytical Atomic Spectrometry", new analyses of "Archaeopteryx"'s feathers revealed that the animal
