This was possible due to the presence of melanin-containing melanosomes, which were preserved in the fossilized feathers. The fossilized remains were from a Jurassic troodontid, Anchiornis huxleyi, an ancestor of Archaeopteryx and modern birds. The presence of colored feather patterns in a bird prior to the evolution of true flight, suggests that feather coloration may have evolved for reproductive or communication purposes.
