President Biden is not the king

US President elect Biden strongly condemned trump at an event held in Wilmington, Delaware, on the 7th local time, NPR reported. On the 6th, a group of trump supporters stormed the U.S. Capitol.
Biden said Wednesday (6th) was one of the darkest days in American history, adding that “no president is the king, and there is no house of Lords in Congress. The judiciary does not serve the will of the president, nor will it protect him or her. “Our president is not above the law. Justice serves the people and does not protect power. The goddess of justice is blind. What we saw yesterday is obviously another violation of the basic principles of this country. “

Discover new dinosaur species

On November 26, Beijing time, today, a team of Chinese and foreign scientists announced in Beijing that they had discovered a new species of megagnathosaurus in Fengning, Hebei Province, which is of great significance for us to understand the evolution of dinosaurs. This research is led by Xing Lida, associate professor of China University of Geosciences (Beijing), Niu Kecheng, executive director of Yingliang stone natural history museum, tetsuto Miyashita, University of Chicago, USA, famous paleontologist, Philip J, University of Alberta, Canada Currie) and other scholars. The research paper was published in the Cretaceous study by Elsevier publishing group.
We know that members of the dinosaur family are not all big men. Meijaya is a very small one. If you add a long tail to a chicken without feathers, add teeth to its mouth, and change the front end of its wings to a small finger claw, it will become a beautiful jaw dragon. Because its body structure is so much like a bird, people thought it was a beautiful jaw dragon when they first found the skeleton fossil of Archaeopteryx.
The distribution of merosaurs, a collection of small theropod dinosaurs, including the historical merosaurs and ornithosaurs, is scattered. Most of the identified members of this branch are found in the upper Jurassic of the Solnhofen islands in Germany and the Yixian Formation of the lower Cretaceous in western Liaoning Province in China. The most typical representative of the former is meijaya dragon, which was found in 1859. It belongs to the primitive small animal foot, but it is the size of a hen, and the long one behind it accounts for half of its body length. They are thin and narrow jawbones and necks. In addition to Europe, a large number of megalophones have also been found in the Jehol Biota in western Liaoning, China. The most famous one is the Chinese Dragon Bird, which was discovered in 1996. It is the first dinosaur with hair on its body. Its discovery strongly proves the hypothesis that birds evolved from dinosaurs.
Xing Lida’s team described a new species, xunmengling yingliangis, which is located in huajiying formation of North China, which is between the two major fossil producing strata. The genus name “swift and violent” expresses that this small dinosaur moves rapidly and has a ferocious disposition. The species name “Yingliang” pays tribute to the Yingliang stone natural history museum, which collects specimens.
Velociraptor, some friends may be familiar with the name Velociraptor, dinosaur movie “Jurassic Park” does not have this “Velociraptor”? Yes, but in fact, the dinosaur in the movie should be called lingdiaolong. Its Latin scientific name is Velociraptor, which means “agile bandit / Raptor”. In Chinese, “smart” means “agile”. So the Chinese name “lingdiaolong” is very suitable for it, which has been widely recognized by the scientific and scientific circles. If it is called “Raptor”, it only translates the meaning of “Agility” and misses the point of “robber / Raptor”. So, since the name Velociraptor has not been used, it can be used to name new dinosaurs.
The difference between Yingliang Velociraptor and other merosaurs is a unique bone form, the phalange IV-4 is longer than iv-3, and a unique combination of posterior cranial bone features, including extra long legs. In phylogenetic analysis, Velociraptors are nested between the groups of Rehe and solenhofen, which is an important supplement to the known branching range and group diversity. In stratigraphy, Velociraptor Yingliang is the earliest and the smallest species in Asia.
Yingliang Velociraptor is a small carnivorous dinosaur living in the early Cretaceous. Its fossils are not complete and its head is missing. However, it can be inferred from similar dinosaurs that its total length is about 60 cm, with a long and flexible neck and a light skull on it. Its teeth in its mouth are small but very sharp, with curved edges. It is a lethal weapon for animals smaller than it 。 Moreover, thanks to its big eyes, Yingliang Velociraptor has a keen eye, which enhances its hunting ability. In addition, Yingliang Velociraptor has strong and long hind legs, which enables it to suddenly accelerate to catch small animals in running, with amazing speed. Even flying insects or running lizards are at risk when the Yingliang Raptor catches prey. With its long neck, it can catch them and crush them with its teeth.
There are still some questions about the habitat preference and diversity model of the dinosaurs, but yingliangxunlong provides us with two more extensive possibilities or bases: (1) based on the diversity of the anti bird assemblage proposed before, huajiying formation may have preserved the oldest fauna in the early Cretaceous Jehol biota, which is related to the late Jurassic Daohugou biota and the late Jurassic Daohugou biota The biological assemblages of Yixian group are different. (2) Velociraptor Yingliang can be a useful calibration point for reconstructing biogeographical and stratigraphic models, and can also be used to estimate the allometric growth trend of the megalophus.
