Eocathayornis was a small, early bird that lived during the Age of Dinosaurs. It could flap its wings powerfully and fly like a modern bird, but it still had teeth and claws on its wings.2

Eocathayornis had a reduced claw on its third wing finger, but the other two wing claws were still present.2

Its radius bone was about three-fourths as wide as its ulna, which helped make its wing strong for flapping.2

The sternum (breastbone) had a keel and a pair of long, backward-pointing processes, adaptations for flight.2

Eocathayornis was about the same size as Cathayornis, another early bird from the same fossil site.2

It lived around 120 million years ago, during the Early Cretaceous period.1

The only known fossil is a skull and upper body preserved as impressions in rock, split into two slabs.1
