But what interests paleontologists in this little ancestral beast is his larynxalmost identical to that of contemporary birds. Which makes scientists say that pUlaosaurus (named as the Pulao, a dragon of Chinese mythology) had to make the same sounds more than our current volatiles.
The preservation of bones linked to vocal organs on dinosaur fossils is very rare, as they are fine and fragile. “”Even when a dinosaur skeleton is preserved, these isolated bones are not always preserved with other elements of the skull“Explain to the New York Times Dr. Xing Xu, paleontologist at the Chinese Academy of Sciences in Beijing and co -author of the article.”These are very fine, very fragile and difficult to preserve bones.“
Pulaosaurus is not very large, barely sixty centimeters. Seeing his reconstruction, you really have little trouble imagining it to push bird cries. But for his titanic congenerss, like T-Rex, Tricératops and other Diplodocus, it’s more complicated. You could say that given their size, these giants were likely to get out of the much more serious and disturbing sounds of their throat.
Well, think again. An older discovery made on a Pinacosaurus, a member of the family of ankylosaurs, on the battleship and the tail in the shape of a mass, suggests that even some large species could make sounds close to piaving. In 2023, other Chinese paleontologists found the same kind of fossilized bones in an individual of this species.
Does that mean that all the dinosaurs were cacking like hens or nipped like sparrows? No. But it means on the other hand that nature, in the jurrassic or in the Cretaceous, also had to Resonate close songs that we can hear in our forests today. These discoveries still confirm a little more the link between prehistoric saurians and their distant descendants, current birds.
