E jele: NamaDinonyana tsa peleKretase ya Pele

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

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

Mosenyi wa ditshomo

Tshomo: Hongshanornis was completely toothless like modern birds.

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

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
E sa ntse e phehwa kgang
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
