4. A small chironomid dinosaur Luan was first discovered in Henan.
This is a small Chironomidae dinosaur found in China, and it is also the first time to find a small Chironomidae dinosaur outside the northwest desert. Previously discovered small Chironomidae dinosaurs (such as Raptors) are all distributed in the Gobi Desert in northwest China. However, compared with the raptors in the northwest Gobi, Luanchuan pink dragon is larger and more like a lizard (only with a little more feathers), so it is closer to the appearance of pink dragon.
Before the beginning of the Yanhuang period, there were all kinds of dinosaurs living here: among the herbivorous dinosaurs, there were sauropods (upper left) and Ankylosaurus (lower left); Among carnivorous dinosaurs, besides Tyrannosaurus Luanchuan, Tyrannosaurus Rex, a huge and fierce dinosaur, also lived here. It can be seen that excitement is not unique to humans.
5. 1 hazka raptor-a dinosaur or a duck?
Hazkarodon is a strange-looking dinosaur, not only in Chironomidae, but also in other grotesque dinosaurs: its mouth is not only long and flat, but also its neck is slender, and its neck is not covered with nerve spines like other dinosaurs, only the second to fifth cervical vertebrae have lower nerve spines (what happened to saliva); The external nostril is behind the main body of maxilla, at the point connecting the anterior branch of maxilla. The descending branch of the posterior orbital bone is rod-shaped This image is described as a wild duck with teeth.
More importantly, Hazka Teratosaurus is 60 cm long, which is similar to mallard. Even it has a life habit similar to waterfowl, which makes it look more like a duck.
5.2 Big Black Dragon-a strange and primitive mysterious dinosaur
The big black dragon is a small Chironomidae dinosaur found in Mongolia. Although it was discovered late in geology, it is a primitive Chironomidae dinosaur. Its generic name comes from Sanskrit and is named after Daiwada, one of the eight protectors of Tibetan Buddhism. Compared with Hazka, it is bigger, and it has the characteristics of hand-velociraptor and near-bird dinosaur.
Compared with other related birds (Chiroptera, odontosaurus, ornithoptera), the detailed characteristics of ulna, femur, ilium and coccyx are different. The midmetatarsal bone of Dracaena dracunculaceae in Xing 'an is uneven, which is the same as that of Archaeopteryx and more evolved Chironomidae, but different from that of the original Papilionidae and some Chironomidae, indicating that the midmetatarsal bone is uneven as a primitive feature. The big black dragon has a typical red dragon's second toe claw.
6. Half bird-the distant ancestor of Gondwana birds
As the name suggests, Hemiptera is a Chironomidae dinosaur, which was distributed in South America in the late Cretaceous. Its pelvic area is very similar to that of early bird archaeopteryx. The forelimbs and shoulder straps of half birds have evolved into structures suitable for flapping-wing flight. However, due to its large size, the wings of the half bird can't drive the body off the ground.
Whether the half-bird evolved from a flying ancestor or the threatening ornithosaur evolved from a Kiosaur independent of the archaeopteryx, (to explain, birds can fly or not) all indicate that birds in this era have evolutionary radiation. In 2005, there was evidence that half birds evolved from bird dragons.
