In a press release, Carney argued against this interpretation, insisting the wing feather was "matte black with a darker tip" and one of his colleagues also brought up the subject in a review paper however, no new evidence was published.

As in the wings of modern birds, the flight feathers of Archaeopteryx were somewhat asymmetrical and the tail feathers were rather broad.

The thumb did not yet bear a separately movable tuft of stiff feathers.

The body plumage of Archaeopteryx is less well documented and has only been properly researched in the well-preserved Berlin specimen.

So it is hypothesized that the pertinent specimens moved along the sea bed in shallow water for some time before burial, the head and upper neck feathers sloughing off, while the more firmly attached tail feathers remained.Using scanning electron microscopy technology and energy-dispersive X-ray analysis, the team was able to detect the structure of melanosomes in the single-feather specimen described in 1861.The resultant structure was then compared to that of 87 modern bird species and was determined with a highest likelihood to be black.The feather studied was most probably a single 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.
