The Six Legendary Dinosaurs(part 1)
Speaking of dinosaurs, many people must have the first impression that they are ferocious and huge, especially the real existence of simulated dinosaurs, which gives us the most intuitive impression. Hundreds of millions of years ago, there were a large number of dinosaurs on the earth. Judging from the fossils that have been discovered so far, there are about 700 kinds.
1. The ancestor of the horned dragon in China
Ceratosaurus includes triceratops, protoceratosaurus, Pentagonosaurus, and other species is the most common simulation animatronic dinosaurs. Ceratosaurus lived in the Cretaceous period. Unlike other dinosaurs, ceratosaurus had unequal Numbers of horns on its head, which were as sharp as rhinoceros horns. Because of the presence of these horns, ceratosaurus increased its fighting power, so ceratosaurus was known as the most fierce plant-eating dinosaur. Ceratosaurus fossils are mostly found in North America, but studies have found that the ancestors of ceratosaurus were actually in north China and the Republic of Mongolia.
According to expert analysis, Protoceratops evolved from Parrot-billed dragons, and Parrot-billed dragons evolved from Chaoyangsaurus. Fossils of Chaoyangsaurus have been found in China. Therefore, it can be said that the ancestor of Ceratopsaurus was in China.
In 1970, a Mongolian and Polish joint archaeological team discovered the fossil of Bagaceratops in the desert. Five complete skulls have been discovered so far. These skulls come from different ages of the Bagaceratops, so paleontology has more research on the growth of Bagaceratops. These fossils are currently deposited at the Paleontological Institute in Warsaw, Poland.
Like other ceratosaurs dinosaurs, Bagaceratops are herbivorous animals. During the Cretaceous period, the geographical range of flowering plants was limited, so Bagaceratops might feed on dominant plants at that time, such as ferns, cycads, and conifers. Bagaceratops may use their sharp beak-like mouth to bite leaves or needles.
2. Three generations of sauropods
The most famous sauropod dinosaurs are Lufengosaurus, Shunosaurus, Mamenchisaurus, etc. These dinosaurs were all herbivorous dinosaurs in the Jurassic period, but the "generations" of these dinosaurs were different. Among them, Lufengosaurus lived in the early Jurassic period 200 million years ago and is the oldest sauropod dinosaur. The second is Shunosaurus, which lived in the mid-Jurassic period 170 million years ago. The last is Mamenchisaurus, who lived in the late Jurassic period 140 million years ago. These three types of sauropods are the three types of dinosaurs that lived at the same time during the Jurassic period. From these dinosaurs, we can see the evolution and migration of sauropods, providing a lot of scientific information for the production and study of simulated dinosaurs.
