酷東西

趣味知識

Dingavis had a very long beak, and most of that beak was made from the upper jaw bone called the maxilla, not the premaxilla like in modern birds.2

The only known fossil of Dingavis is an almost complete skeleton with skull, and it even has feather remains preserved around the neck.1

About forty gastroliths, which are stones that some animals swallow to help grind food, were found with the Dingavis fossil.1

Dingavis lived during the Aptian age of the Early Cretaceous, about 122 million years ago.1

The fossil of Dingavis was found in the Jiufotang Formation, a rock layer famous for many amazing feathered dinosaur fossils.4 2

發現: The Dingavis fossil was found at Sihedang in Liaoning, China, and was named in 2015 by Jingmai O'Connor, Wang Min, and Hu Han. The specimen is kept at the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing.1
仍有爭議: Scientists are still debating exactly how Dingavis is related to other early birds, and whether its long beak was used for a special kind of feeding.2
