How Do Paleontologist Know What Color Dinosaurs Were?
By analyzing the fossilized melanosomes (pigment cells) in the fossil with scanning electron microscope techniques, the researchers compared their arrangements to those of modern birds. In Microraptor, these cells were shaped in a manner consistent with black, glossy coloration in modern birds.[14]
Are Dinosaur Colors Accurate?
Taking a pigment discovery further, scientists accurately color entire body, study says. For the first time, scientists have decoded the full-body color patterns of a dinosaur, a new study in the journal Science says.[15]
