Archaeornithura is the oldest known ornithuromorph, the group that includes all living birds.2 1

It lived 130.7 million years ago, which is about 5 to 6 million years older than any other known ornithuromorph.1

This bird had a well-developed alula, a small feathered finger on the front edge of its wing that helps with maneuverability in flight.2

Archaeornithura had fan-shaped tail feathers and a U-shaped furcula (wishbone), features seen in modern birds.2

Only two fossils of Archaeornithura have been found, both from the Huajiying Formation in China.2 1

Its discovery pushed back the first appearance of ornithuromorph birds by about 6 million years.1

Nhunumu: Archaeornithura was named in 2015 by a team led by Wang Min and Zhou Zhonghe. The fossils were bought from a fossil dealer and came from the Huajiying Formation in Hebei, China.2 1
Wɔda so gye ho akyinnye: Scientists are still debating exactly how Archaeornithura is related to other early birds and whether it was a wading bird like its relatives.1
