VOICED : Fosil de ave da pistas sobre comunicacion entre especies

Argentinian scientists have unveiled a 70-million-year-old fossil of a Mesozoic bird found in Antarctica, notable for its unique morphological feature, the 'cirinje' in its trachea, which allowed it to produce sounds similar to modern ducks. This discovery sheds light on how dinosaurs, including birds, evolved their communication methods and how sound production influenced brain development. The fossil, named Begabiciay, was discovered in 1992 and studied for over two decades. The scientists emphasize the importance of maintaining science funding despite economic challenges.
