In the years of 160 million years,hotly discussed information the earth was occupied by dinosaurs.These reptiles were the overlords of the entire world at the time, and they were omnipotent.Bawang dragons, spiny dragons and other beast -footed dinosaurs ruled the mainland. Pterosaur occupied airspace. In the ocean, there was a more fierce creature — Canglong (Note: Pterosaur and Canglong are not dinosaurs).
In 2006, Akihiro Misaki, the paleontologist of the History History History Museum of Northern Kyushu City, found an paleontological remains in Tamagawa, Kogosama, Katsuyama, Japan.It is exciting that the integrity of this remains is quite high, and it is the most complete fossil discovered by the entire Northwest Pacific Ocean, which seems to be more precious.The paleontologist took 5 years to completely excavate the bone fossils.
This excavated fossil belongs to a Canglong.Canglong is a kind of ancient giant beast living in the dinosaur era, and dinosaur is a relative.According to the current research, the longest Canglong can grow to 17 meters, 4 meters longer than the longest Tyrannosaurus dragon.At that time, various creatures in the ocean were as small as shellfish, turtles, as large as sharks, snake -necked dragons, and even similar. They did not let go. In the 20 million years, they were well -deserved marine hegemon.
However, the Canglong fossils discovered this time are not so huge, about 6 meters in length, which is almost the same as a truck.Just after excavation, Japanese paleontologists nicknamed it: Wakushan "Blue Dragon", which is a monster in local folklore.Recently, paleontologists have finally determined the name -MegapTerygius Wakayamaensis.
On this fossil, we can see that the top of its back spine is slightly raised, which is a bit similar to dolphins or porpoons.We know that there are dorsal fins on the back of the dolphin, which can provide additional stability when swimming.Paramiamists have speculated that there may be this structure on the body of Heshan Blue Dragon.
The most distinctive thing is that the two -dragon -like feet in Ge Shan, especially the two in the back, are particularly longer compared with the same kind living in other regions.Its unique appearance made Takuya Konishi, a antique biologist at the University of Cynnons, who thought of Canglong, was also confused.
He mentioned: "From fish, penguins to turtles, we have not found any modern animals to have such a body. There is no kind of animal that has such four huge feet, and the dorsal fins play a role in swimming."
The paleontologist team from Japan has the characteristics of modern whales to control the direction of the movement, and it is speculated that the fins of Geyama Blue Dragon are probably the same function. As for its tail, it is likely to provide thrust.We can see from the middle of Figure 5 that the tail of the snake -necked dragon is slender. In contrast, the tail area of the Gogshan Blue Dragon is larger, and it can provide stronger thrust.Researchers speculate that this is the key to allowing Canglong to crush the snake -necked dragon in terms of combat effectiveness.
