The double-headed dragon’s head shape is very strange among dinosaurs. The roosters in our lives are famous for flower crowns. Double-crown means that there are two such crowns. Male peacocks during the courtship of double-crowned dragons attracted the attention of females. It will show off its own tail. We call this the peacock. In the ancient Jurassic era, dinosaurs did similar things to attract the attention of the opposite sex. This kind of dinosaur is a dilophosaurus. This is another A name.
Around the summer of 1944, paleontologists discovered the first specimen of Dilophosaurus. Due to the limited knowledge of paleontology at that time, he named it Wei’s spotted dragon. Until 1970, he discovered another species of this species. With specimen. This time, the specimen had a pair of bone-crowned heads. This made Will realize that this was a new dinosaur species, so he named it Dilophosaurus based on the characteristics of the specimen.
The dilophosaurus has good eyesight, a high nose, and a crescent-shaped pair of huge ancient crowns on the skull. Bright colors and patterns on it can attract the opposite sex. However, these bone crowns are very fragile and cannot be used in combat. The anterior orbital window on the dilophosaurus skull is larger than the orbital, the jaw is very developed, and the mandible is relatively long. At the same time, the teeth of the upper jaw are longer than the teeth of the lower jaw, and the teeth with mouth are like sharp knives.
Dilophosaurus teeth also have small serrations on the front and back edges, which makes it easy to shred any captured prey and swallow large pieces of meat into the belly. In addition, there are holes in the skull behind the eyes. These holes are used to better attach to the muscles that affect the jawbone. The biting force is visible.
The dilophosaurus, which is about 2.5 meters tall when standing, is slightly weaker than other carnivorous dinosaurs in the later period, but its hind legs are strong and powerful for running, and its forelimbs have long claws, which are suitable for tearing. These substances make it Become the most brutal and ferocious carnivorous dinosaur in the Early Jurassic ecosystem. What the recipe space contains is a question that paleontologists have been arguing about. Dilophosaurus with developed hind limbs can quickly chase herbivorous dinosaurs, such as sprinting for small, slightly defensive bird-footed dinosaurs, or Larger and heavier sauropod dinosaurs. After chasing the prey, it will use the long teeth to bite and simultaneously swing the claws on the fingers of the toes to grasp the food, then open the mouth of the blood basin and tear the prey severely. Not only that, Dilophosaurus can also use its flexible front jaw to pick up small lizards from dense fern bushes and stone slits to remember the muscle filling.
However, when food is scarce, due to the fact that Dilophosaurus has a unique skin that cannot be torn, and a hooked beak, some paleontologists think that Dilophosaurus may eat animal carcasses like ****. And you can use the crown-like spine to open the skin on the chest to prevent them from closing in order to better enjoy the internal organs of the prey. The difference is that it only has the bodies of large protosaurians. The dilophosaurus fossil unearthed in Yunnan, China seems to support this point. Two complete dinosaur skeletons are twisted together. One of them is a Protosaurus and the other is a dilophosaurus. The former is above the tailbone.
Paleontologists have speculated based on this buried state of the fossils that the two dinosaurs may have died for two reasons; one is that they have both died and died in a life-and-death struggle. The other is that the original sauropod dinosaur may have been dead for many days, and the meat on the carcass has deteriorated, and this dilophosaurus may have been hungry for too long, so it did n’t care too much, and it started to bloom. He died of poisoning. Dilophosaurus is one of the members of the dinosaur fauna of the Ring of Tethys Sea, so their species found throughout the world are very similar. Their fossils have been found even in Antarctica, indicating that Antarctica, which is now ice-snowy, may have been A warm heaven.
