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.

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

A 'one of a kind' fossil discovery could transform our understanding of how the unique brains and intelligence of modern birds evolved, one of the most enduring mysteries of vertebrate 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,

Researchers hope the "exquisitely preserved" fossil will cast new light on an enduring mystery in paleontology.

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,
