For the first time, an ancient bird fossil was discovered in the Middle Ages

On October 19, Argentine scientists discovered the 70 million-year-old fossil Antarctic of a Middle-aged bird that still has a tracheal structure that can generate sound signals to help the species communicate. together.

Expert Fernando Novas of the Argentine National Council for Scientific and Technical Research (Conicet) judged that this is the first time researchers have discovered the ancient bird fossil of the Dai Trung Sinh era and especially the specimen. keep tracheal tube structure.

Through research programs, scientists have concluded that the trachea has allowed birds to produce a sound signal that communicates at the end of the Dinosaur era.

Fossil birds are found in Vega Island, Antarctica. This is the Vegavis iaai bird , a new species of the Anseriforme family discovered in Antarctica, in the Cretaceous period, about 65 to 70 million years ago. This platypus has a small shape, about 50cm in length and weighs 1.5kg.

American researcher Julia Clarke, of the University of Texas, was the first to discover that fossil birds still retain the trachea tube when she performs it on a 3D scanner.

This discovery allows people to understand how dinosaurs, including birds that convey how to communicate with each other, and how the body is capable of producing sounds and noises to brain development.

Besides, this new discovery also opens the door to studying aspects of dinosaur behavioral evolution for tens of millions of years.

Earlier, Argentine researchers found fossils of a giant prehistoric bird with the largest wingspan ever recorded living about 50 million years ago in Antarctica.

This giant bird is a species of pelagornithid , a giant extinct seabird family, with hard bone-like teeth.

This bird can grow to gigantic sizes about 50 million years ago, when ocean temperatures are warm and food is abundant.
