Utuntu dushimishije

1

Chupkaornis is the oldest known hesperornithiform bird from Asia, living about 89 to 83 million years ago.2

2

Its name comes from the Ainu word 'chupka' meaning 'eastern', because it was found in East Asia, unlike its relative Hesperornis which means 'western bird'.1

3

Chupkaornis could not fly. Its wings were tiny, and it used its strong legs and feet to push itself through the water.2

4

The only known fossil of Chupkaornis includes nine bones: neck vertebrae, back vertebrae, part of the thigh bone, and part of the shin bone.1

5

It was discovered in 1996 by two amateur fossil collectors, Masatoshi and Yasuji Kera, and was named after them.1

6

Chupkaornis had special joints in its backbone that allowed it to bend its neck and body while diving.2
