Its cerebellum, a brain structure that in living birds helps coordinate motor control during flight, was smaller than in today's avian species and more like Archaeopteryx's. But its brain was connected to the spinal cord in a fashion similar to modern ...

Paleontologists have unearthed a well-preserved skull fossil that could advance our understanding of avian intelligence.

Navaornis fills a ~70-million-year gap in our knowledge of the evolution of the unique bird brain. Navaornis hestiae (centre) documents a previously unknown intermediate stage in the evolution of the central nervous system between the earliest birds (e.

Birds descended from the dinosaurs, but researchers have known relatively little about how the bird's brain took shape over millions of years. A new fossil sheds light on that mystery.

Palaeontologists have pieced together the brain structure of a bird that lived 80 million years ago named Navaornis hestiae, thanks to a remarkably well-preserved fossil
