Navaornis was a starling-sized bird that lived about 80 million years ago in what is now Brazil. It had a toothless, large-eyed skull that looked almost like a modern bird, but it belonged to an ancient group called enantiornithines. Its beautifully preserved skull let scientists see inside its brain for the first time in such an old bird.1 2

Makambo ya kosepelisa

Navaornis had a toothless skull with large eyes, just like many birds today, but its brain still had some ancient features like a small cerebellum and a weakly expanded telencephalon.1

Its skull is the best-preserved Mesozoic bird skull ever found, preserved in three dimensions without being flattened.1

Navaornis lived around 85 to 75 million years ago, during the Late Cretaceous period.1 2

The fossil site where Navaornis was found is very small, only about 6 square meters, but it has yielded hundreds of enantiornithine bird bones.1

Navaornis belongs to a group called Enantiornithes, which were the most diverse birds of the Mesozoic and lived on every continent except Antarctica.1 2

Its inner ear (bony labyrinth) was shaped like that of many modern birds but was much larger.1

Ntango bamonaki yango: The fossil site was discovered in 2004 by William Nava, and the holotype skull was found in 2016. The species was named Navaornis hestiae by Chiappe and colleagues in 2024.1 3
Naino bazali kowelana: Scientists are still debating exactly how Navaornis is related to other enantiornithines, because its toothless skull and modern-looking head make it hard to place in the family tree.1
