An analysis of 12 fossilized dinosaur eggshells from Europe, Asia, North America and South America detected the same two pigments present in colorful birds eggs in a dinosaur group called eumaniraptorans, which includes well-known meat eaters like Velociraptor and the small feathered dinosaur ancestors of birds.

"Our study fundamentally changes our understanding of egg color evolution, and adds color to dinosaur nests in the real 'Jurassic World'." For example, the sickle-clawed predator Deinonychus had a blue egg with brown blotches and the bird-like Oviraptor, known for its toothless beak, had eggs that were dark blue. read more
