The Color of Dinosaurs

Scientists have figured out how to tell what color some dinosaurs were just by looking at their fossils.

Here’s how they did it:

Dr. Prum and his colleagues took advantage of the fact that feathers contain pigment-loaded sacs called melanosomes. In 2009, they demonstrated that melanosomes survived for millions of years in fossil bird feathers. The shape and arrangement of melanosomes help produce the color of feathers, so the scientists were able to get clues about the color of fossil feathers from their melanosomes alone.

Human ingenuity never ceases to amaze.
