Cathayornis had a long, toothy snout and perching feet, like many enantiornithean birds.1

It had large claws on its first two fingers that helped support its wings.1

Only one definite fossil of Cathayornis yandica has been found, catalog number IVPP V9769.1

Cathayornis lived about 120 million years ago, during the Aptian age of the Early Cretaceous.1

Some scientists once thought Cathayornis was the same as Sinornis, but later studies showed they are different.1

Several other species were once called Cathayornis, but most have been reclassified or are now considered doubtful.1

Ku tas léeb yu dul dëgg
