As per a new research, it is stated that giant flying pterosaurs roamed all over the world in the Late Cretaceous Period, 60 million years ago.
As per Live Science, the researchers, who published this study in the ZooKeys journal stated that the ancient dinosaurs had wingspans of 39 feet. Also, the pterosaur dragons don’t have teeth. Dr. Alexander Averianov of the Zoological Institute of the Russian Academy of Sciences the author of the study said that “This shift in dominance from toothed to toothless pterodactyloids apparently reflects some fundamental changes in Cretaceous ecosystems, which we still poorly understand,”
The Pterosaurs belong to the same family of dinosaurs like pterodactyl and they are so large that momentum has to be built up on the ground before they take flight. Also, as per the analysis of previous fossil, it was showed that the Pterosaur was the first vertebrate to fly, somewhere around 220 million years ago.
Currently, Azhdarchidae is like a nightmare for paleontologists. Most taxa are known from few fragmentary bones, which don’t overlap between the name taxa. Some skeletons are preserved poorly and some material has remained undescribed since last 40 years.
In general, the evolutionary history of the pterosaurs is incomplete because their fossils were rare and bones were delicate, reports Live Science. Before the research was published, the analysis of the Azhdarchidae fossil was done on the basis on incomplete skeletons or fragments of bones.
A rare pterosaur was discovered by scientists who fossil was unearthed in Brazil with a bony ridge on head and which resembled butterfly wing. A unique thing about the discovery was that 47 identifiable individuals were found at the site. Most of them were juveniles, however, it was believed by the researchers that the bone fragments may have belonged to 100s more than just identifiable ones.
