New Fossil Birds Discovered Near China’s Great Wall – One Had a Movable, Sensitive 'Chin'
China's Great Wall is not only a historical landmark but also a treasure trove of fossils. Recently, a team of scientists discovered new fossil birds near the Great Wall, and one of them had a unique feature - a movable, sensitive 'chin.' This discovery sheds light on the evolution of birds and their adaptations to their environment.
The Discovery
The team of scientists from China and the United States discovered two new species of fossil birds in the Hebei Province near the Great Wall. The fossils were found in rocks that date back to the Early Cretaceous period, about 120 million years ago.
One of the species, named Falcatakely forsterae, had a unique feature - a movable, sensitive 'chin.' This feature is similar to that of modern-day birds like chickens and ducks. The 'chin' is actually an extension of the lower jaw bone, which is called the mandible. In Falcatakely forsterae, this extension was long and thin and could move up and down independently.
The Significance
The discovery of Falcatakely forsterae is significant because it provides insight into the evolution of birds. Birds are descendants of dinosaurs, and their evolution involved many adaptations to their environment. The movable 'chin' in Falcatakely forsterae is an adaptation that allowed it to catch prey more efficiently.
Birds use their beaks to catch prey, but some prey can be slippery or hard to grasp. The movable 'chin' in Falcatakely forsterae would have allowed it to grasp prey more securely by using both its beak and its 'chin.' This adaptation may have given Falcatakely forsterae an advantage over other birds that did not have this feature.
Other Discoveries
The discovery of Falcatakely forsterae is not the only significant find in the Hebei Province. The same team of scientists also discovered another new species of fossil bird, named Juehuaornis palmapenis. This species had a unique feature as well - its wings were adapted for gliding.
Juehuaornis palmapenis had long feathers on its wings that were shaped like those of modern-day gliding birds. This adaptation allowed it to glide through the air, which would have been useful for escaping predators or traveling long distances without expending too much energy.
Conclusion
The discovery of new fossil birds near China's Great Wall is an exciting development in the field of paleontology. The fossils provide insight into the evolution of birds and their adaptations to their environment. The movable 'chin' in Falcatakely forsterae and the gliding wings of Juehuaornis palmapenis are just two examples of the many adaptations that birds have developed over millions of years.
