The “one-of-a-kind” fossil of Navaornis hestiae helps fill a giant gap in scientists’ understanding of how bird brains evolved.

A rare 80-million-year-old fossil bird skull is helping scientists decode how modern bird intelligence evolved.

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.

Interestingly, this fossil fills a 70-million-year-long gap in our knowledge between the early bird-like dinosaurs (Archaeopteryx) and modern birds.

A research team used state-of-the-art micro-CT scanning technology to reconstruct the bird’s skull and brain in remarkable detail.

The brains of today's birds facilitate a level of cognitive prowess and behavioral complexity rivaled only by mammals. But how the avian brain evolved over many millions of years from an ancestral dinosaurian form has long puzzled scientists.

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
