"This fossil is truly so one-of-a-kind that I was awestruck from the moment I first saw it to the moment I finished assembling all the skull bones and the brain, which lets us fully appreciate the anatomy of this early bird," said Navalón. "Modern birds ...

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

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.

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.

A unique fossil discovery in Brazil provides new insights into bird brain evolution, while a study highlights drastic population declines in African elephants over the past 50 years. The skull of a bird species,

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
