When scientists examined its feathers under a high-powered microscope

Of course, it's more complex than this.The melanosomes are packed together inside cells, and other factors, like how the melanosomes are arranged within the feather, also matter.Let's return to the microraptor fossil.When scientists examined its feather imprints under a powerful microscope,they found nanostructures that look like melanosomes.X-ray analysis of the melanosomes further supported that theory.
They contained minerals that would result from the decay of melanin.
