酷東西

趣味知識

Heyuannia was the first oviraptorid dinosaur ever found in China. Most other oviraptorids come from Mongolia.2

Its eggs were blue-green in color, like the eggs of American robins. This color may have helped hide the eggs or send signals to other dinosaurs.2

Thousands of eggs have been found at the same site as Heyuannia, and some were probably laid by this dinosaur.2

Heyuannia had very short arms and its first finger was tiny. Its thumb claw was twice as big as the second claw.2

One fossil of Heyuannia may preserve reproductive organs, which is very rare for dinosaurs.2

Scientists think Heyuannia sat on its eggs to keep them warm, but it could not cover all the eggs at once. The outer eggs were cooler than the inner ones.2
