趣味知識

Enantiornis is one of the earliest known birds, living from about 94 to 66 million years ago.4

It had a special shoulder joint that worked differently from modern birds, which is why it is called an 'opposite bird'.1

Fossils of Enantiornis have been found in both South America and Central Asia, showing it lived in warm, wet environments.4

This bird was about the size of a crow, with a wingspan of roughly half a meter.2

Enantiornis had teeth in its beak, which helped it catch and eat prey.1

It lived on the ground and could fly, but probably spent a lot of time walking or running.4
