Anchiornis
Anchiornis was a tiny, feathered dinosaur that lived in what is now China. It was about the size of a crow and had long feathers on its legs, making it look like a four-winged creature. Scientists think it could glide or flap its wings to move between trees.21

עובדות כיפיות
Anchiornis is one of the smallest non-avian dinosaurs ever found, weighing only about 110 grams (4 ounces).1
It had long feathers on its feet, which gave it four wings. This helped it balance and steer while gliding.2
Anchiornis lived around 160 million years ago, during the Jurassic Period. That is older than Archaeopteryx, the first known bird.32
Its name means 'near bird' because it is very close to the ancestors of modern birds.1
The wrist bones of Anchiornis were already adapted for folding its wings, a feature seen in later birds.1
