80 million-year-old dinosaur-era fossil bird offers insight into brain evolution
Interestingly, this fossil fills a 70-million-year-long gap in our knowledge between the early bird-like dinosaurs (Archaeopteryx) and modern birds.
Small fossil has big implications for bird brain evolution
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.
Fossil Discovery Sheds Light on Bird Brain Evolution
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,
'One-of-a-kind' skull fossil from Brazil reveals bird brain evolution
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.
'One-of-a-Kind' Fossil From Age of Dinosaurs Reveals New Early Bird Species
Researchers hope the "exquisitely preserved" fossil will cast new light on an enduring mystery in paleontology.
‘One of a kind’ fossil from the age of dinosaurs reveals roots of bird intelligence
The fossil bird, which has been named Navaornis hestiae, lived approximately 80 million years ago in what is now Brazil, before the mass extinction event that killed all non-avian dinosaurs. It was discovered by palaeontologist William Nava, for whom the species is now named after.
Exquisite bird fossil provides clues to the evolution of avian brains
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
Prehistoric ‘bird brain’ fossil reveals evolution of avian intelligence
A bird brain from the age of dinosaurs reveals the roots of avian intelligence, according to a new study. The "one of a kind" fossil discovery could transform our understanding of how the unique brains and intelligence of modern birds evolved,
