Une découverte de fossile pourrait transformer notre compréhension de l’évolution du cerveau des oiseaux
Picture MUST credit: Stephanie Abramowicz A 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. Researchers have identified a remarkably well-preserved fossil bird, roughly the size of a starling. from the Mesozoic Era . This period lasted from 252 million to 66 million years ago when an asteroid strikes is believed to have prompted the extinction of the dinosaurs. The complete skull has been preserved almost intact:, a rarity for any fossil bird, but particularly for one so ancient, making this one of the most significant finds of its kind. The three-dimensional preservation allowed the researchers, led by the UK’s University of Cambridge and the Los Angeles County Natural History Museum in the USA, to digitally reconstruct the brain of the bird, which they have named Navaornis hestiae. Navaornis lived approximately 80 million years ago in what is now Brazil. The researchers say their discovery could be a sort of ‘Rosetta Stone’ for determining the evolutionary origins of the modern avian brain. The fossil fills a 70-million-year gap in our understanding of how the brains of birds evolved: between the 150-million-year-old Archaeopteryx, the earliest known bird-like dinosaur, and birds living today.
