In the course of excavations in Antarctica, the researchers were able to find out what was like the singing of the first birds and dinosaurs. This is stated in an article published in the journal Nature.
Franz Goller (Franz Goller) from the University of Utah in salt lake city, along with colleagues discovered the remains of a direct relative of modern birds is Vegavis iaai, which lived during the Mesozoic the Arctic circle. The remains perfectly preserved, allowing scientists to examine not only the bones and feathers, and imprints of soft tissues. With the help of the scanner Goller was able to study the structure of the Syrinx — the vocal organ of birds, located at the base of the trachea.
A comparison of this body of ancient and modern birds has allowed to establish that it practically repeats the structure of the Syrinx geese, ducks and other birds without singing skills. Based on this Goller claims that Vegavis iaai at least could quack and buzz.
While the dinosaurs that were the closest contemporaries of birds, no such body exists. Accordingly, they could only emit guttural sounds, not opening his mouth. The authors conclude that the ability to issue complex sounds, like sounds, could be one of the key factors in the development of birds and the evolutionary advantage compared to other types of archosaurs.
In July 2016, scientists have learned that dinosaurs are not roaring, opened his mouth, and cooed, and was sent with my mouth closed, like the modern birds. Many dinosaurs also fanned neck and made karlikaya sounds to attract females and repel competitors. The closest analogue among modern birds can be ostriches.
