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

Ishusho ya Archaeornithura yakozwe na AI — Ishusho yakozwe na AI yerekana uko Archaeornithura ishobora kuba yari isa, yakozwe na mudasobwa hashingiwe ku byo abahanga bazi. Ni ugukeka gusa: inyamaswa nyayo ishobora kuba yari isa ukundi, kandi nta muntu uzi amabara yayo nyayo.
