Cruralispennia was a tiny, feathered bird that lived about 131 million years ago in what is now China. It had strange, wiry feathers on its legs that no other bird had before or since!1

Cruralispennia had a plough-shaped pygostyle, a fused tail bone that was thought to only exist in more advanced birds. This shows that different bird groups evolved similar features separately.1

Its leg feathers were unlike any seen before: the base was like a stiff wire, and the tip was fluffy and split into many tiny strands.1

Even though Cruralispennia lived very early in bird history, its shoulder bone (coracoid) was already very slender, a shape usually found in later Cretaceous birds.1

The name Cruralispennia means 'leg feather' in Latin, because of the unusual feathers on its shin bone (tibiotarsus).1

This bird had 14 teeth in its lower jaw, which is why its full species name is multidonta, meaning 'many teeth'.1

Cruralispennia lived alongside other early birds like Protopteryx and Eoconfuciusornis in the same ancient lake environment.1

Ekifaananyi kya Cruralispennia ekyakolebwa AI, nga kiraga engeri gye yayinza okuba ng'afaanana, ekyakolebwa kompyuta okusinziira ku ebyo bannassaayansi bye bamanyi. Kuteebereza: ekisolo ekyennyini kiyinza okuba nga kyali kifaanana bulala, era tewali amanyi langi zaakyo ez'amazima.

Ebibuuzo ebisinga okubuuzibwa ku Cruralispennia

?How big was Cruralispennia?

Cruralispennia was a tiny bird, about the size of a modern sparrow. Its leg feathers were only 12 to 16 mm long.2 3

?Where did Cruralispennia live?

It lived in what is now China, around a lake in the Sichakou Basin about 131 million years ago.2

?What did Cruralispennia eat?

Scientists think Cruralispennia likely ate insects or small prey, because it had sharp, curved claws and many teeth in its lower jaw.2 3
