What color does flying dinosaur eggs live 66 million years ago?

A new study published in the journal Peerj, USA helped answer some questions of many people that dinosaurs spawn in what color?

Accordingly, the scientists found an egg nest in green (blue and blue combination) belonging to Heyuannia huagi dinosaurs - living between 145.5 and 65.5 million years - in China. This is a dinosaur with a small body, short, no fangs, living mainly in China and Mongolia.

Colored eggs appeared earlier in the dinosaur family.(Illustration).

Blue eggs are found in many modern birds and people have long believed that only the animals of the new bird family have green eggs. This new finding shows that colored eggs appeared earlier in the dinosaur family and it may appear along with the habit of nesting and laying open eggs on the nest, instead of buried in the ground, of animals.

"Future studies may show the potential link between green eggs and collective nesting habits, " the researchers said.

There are 2 types of pigment that help regulate the color of the egg: biliverdin regulates green, protoporphyrin regulates reddish brown, often appearing in the form of spots or other shapes. However, according to scientists' research, the amount of biliverdin pigments in dinosaur eggs is much higher, indicating that the eggs are only blue without reddish brown.
