Specimens of Archaeopteryx colouration and patterning of the plumage cannot be drawn with certainty from this study. In 2011, graduate student Ryan Carney and colleagues performed the first colour study on an "Archaeopteryx" specimen with the fossil of this single feather. Using scanning electron microscopy technology and energy-dispersive X-ray analysis, the team was able to detect the structure of melanosomes in the fossil. The resultant structure was then compared to that of 87 modern bird species and was determined with a high percentage of likelihood to be black in colour. While the study does not mean that "Archaeopteryx" was entirely black, it does
Specimens of Archaeopteryx than flight. Pennaceous feathers thus represent an exaptation and were only later adapted for aerodynamic capabilities, a function that was apparently convergent among different groups within Avialae. In February 2014, the existence of a twelfth specimen was announced from an Altmannstein quarry near the Schamhaupten district of Bavaria. This specimen was unearthed by a private collector in 2010.. Based on a new diagnosis for the genus Archaeopteryx, by the German paleontologist Oliver Rauhut c.s., the Berlin, Eichstätt, Solnhofen, Munich, Daiting, Thermopolis, 11th, and 12th specimens can be referred to this genus with high certainty.
