Hongshanornis was a small, beaked bird that lived near lakes and marshes in Early Cretaceous China. It had long legs for wading in shallow water and a slender beak for catching fish or bugs. This bird is one of the earliest known beaked ornithurine birds, a group that includes modern birds.1

Ebyewuunyisa

1

Hongshanornis had a beak in both its upper and lower jaws, making it the earliest known beaked ornithurine bird.1

2

This bird had a predentary bone in its lower jaw, a feature once thought unique to ornithischian dinosaurs.1

3

Hongshanornis lived about 125 to 120 million years ago, during the Early Cretaceous period.2

4

Its long legs and short, less curved claws show it was a wading bird, not a tree-dweller.1

5

One fossil of Hongshanornis preserved gizzard stones (gastroliths), which helped it grind up food.3

6

Hongshanornis was originally thought to be toothless, but later studies found it had small teeth in both jaws.3

Omumenyi w'enfumo

Enfumo: Hongshanornis was completely toothless like modern birds.

Amazima: Scientists now know it had small teeth in both upper and lower jaws, though it also had a beak.3

Okuzuulibwa
Hongshanornis was named by Zhou and Zhang in 2005. The first fossil, a nearly complete skeleton with feathers, was found in the Yixian Formation at Shifo, Ningcheng, Inner Mongolia, China.12
Kikyakubaganyizibwako ebirowoozo
Scientists still debate whether Hongshanornis was more closely related to modern birds than toothed ornithurines, or if teeth were lost several times in early bird evolution.1
