What color were the dinosaurs?
Summary
Scientists have studied the microscopic structures of fossilized dinosaur feathers in order to determine the colors of extinct dinosaurs. They discovered that melanin comes in different shapes, which produce different colors. This has revealed that some dinosaurs were iridescent and others had complex camouflage. Scientists were able to determine that dinosaurs such as Velociraptor had iridescent feathers and that Anchiornis had black and white wings with a red crest. Through this research, scientists have been able to gain insight into the habitats and lifestyles of extinct dinosaurs.
Q&As
What colors were the dinosaurs?
Some dinosaurs were iridescent and others were camouflaged.
How do we know the actual colors of extinct animals?
Scientists can determine the actual colors of extinct animals by looking for melanosomes, which are microscopic blobs of melanin, the pigment that colors hair, skin, feathers and eyes across the animal kingdom.
How did scientists determine the color patterns of dinosaurs like Velociraptor?
Scientists determined the color patterns of dinosaurs like Velociraptor by looking for melanosomes that were either sausage-shaped or meatball-shaped.
What does countershading indicate about a dinosaur's habitat?
Countershading indicates that the animal probably lives in an open environment if the countershading is sharp and high on the body, or a forest environment if the countershading is more gradual and low on the body.
What did the first dinosaur Jakob Vinther studied look like?
The first dinosaur Jakob Vinther studied, Anchiornis, had a gray body, white wing feathers with black splotches at the tips, and a red crown like a woodpecker's.
AI Comments
👍 This article is incredibly interesting and informative. It provides a great overview of the color of dinosaurs and how scientists are able to determine the colors of extinct animals.
👎 This article is too long and could have been condensed into a shorter format. It also relies too heavily on scientific jargon and could have been written in a more accessible way.
AI Discussion
Me: It's about the colors of dinosaurs and how scientists have been able to determine the colors and patterns of dinosaurs from fossilized feathers. It's really interesting!
Friend: Wow, that is really interesting! So what are the implications of the article?
Me: Well, it shows us that dinosaurs were much more colorful than previously thought, with some having iridescent feathers and others having camouflage patterns. It also suggests that some dinosaurs were more vulnerable to predators than we previously thought, despite their size and armor. Finally, it shows us that melanin can survive the fossilization process, allowing us to learn more about the colors and patterns of extinct animals.

Technical terms
- Melanosomes
- Microscopic blobs of melanin, the pigment that colors hair, skin, feathers and eyes across the animal kingdom.
- Iridescence
- A metallic sheen created by ordering melanin in a specific way inside the feather in order to interact with light.
- Countershading
- A kind of natural camouflage in which the parts of an animal that would usually be in shadow have a lighter pigment than the parts that would usually be in sunlight.
