makambo ya kitoko

Makambo ya kosepelisa

1

Yatenavis is known from just a single bone: the lower half of a right wing bone (humerus).21

2

It lived about 72 to 66 million years ago, during the Maastrichtian stage of the Late Cretaceous.3

3

Yatenavis is the southernmost enantiornithine bird ever discovered anywhere in the world.21

4

It was one of the smallest enantiornithine birds from the Late Cretaceous of South America, about the size of a sparrow.21

5

Its name comes from the Aoni Kenk word for 'stone' and Latin for 'bird', meaning 'stone bird'.1

6

Yatenavis lived alongside other birds, including a larger enantiornithine and a bird called Kookne yeutensis.1

7

The fossil was found in the Chorrillo Formation, which was formed by a river system in a cold, high-latitude environment.21

Ntango bamonaki yango
Yatenavis was named and described in 2023 by a team of Argentine and Japanese scientists, including Gerardo Álvarez Herrera and Federico Agnolín. The single fossil bone was found during a joint expedition in March 2022 at Estancia La Anita in Patagonia, Argentina.21
Naino bazali kowelana
Scientists are not sure exactly what Yatenavis looked like or how it behaved, because only a single wing bone has been found.21
