吃：肉肉食恐龍白堊紀早期

Overoraptor was a small, fast meat-eating dinosaur that lived in what is now Argentina. It had strong arms and a special claw on its second toe that it used to catch prey. Scientists think it was very bird-like and may help us understand how birds evolved.1

酷東西

趣味知識

Overoraptor's bones have a pattern of light and dark spots, which is why it was named 'piebald thief'.1

It had a special 'raptorial' claw on its second toe, like a Velociraptor, which it used to slash at prey.1

Overoraptor had very bird-like arms, with a strong ulna and a saddle-shaped joint in its wrist that helped it move its hands like a bird folding its wings.1

It lived about 100 to 90 million years ago, during the Late Cretaceous period.2

Overoraptor was a gracile dinosaur, meaning it had a slender, lightweight body built for speed.1

Its fossils were found together with crocodile and turtle bones, suggesting it lived near water.1
