This is a dinosaur you haven't seen before, the "Aratadosaurus" found in Brazil, which weighs less than adults
According to the People's Daily, archaeologists from Brazil's National Museum of Natural History and a number of universities have jointly released the latest archaeological findings, in the Alarippi Basin of ceará state in northeastern Brazil, archaeologists found a dinosaur fossil, surprisingly, this dinosaur is a completely new species, archaeologists currently name it "Ala tarrosaurus".
What does Alatalong look like?
Through chronological analysis, the fossils of Alatalong come from the early Cretaceous Period, and scientists believe that Alatalong appeared on Earth about 110-150 million years ago. Their size is not very large among dinosaurs, the body length is about 3 meters, the weight is 70 pounds, but in fact, how big the Arataurus is, archaeologists are still studying, because the fossils of Alataurus found so far, in fact, it is still in its infancy and has not yet fully developed.
In the Alarippi Basin where Alataron was discovered, it is a rich fossil treasure area in the eyes of archaeologists, with a large number of fossils from the age of dinosaurs, and many animals living at the same time as dinosaurs. Before the discovery of Aratosaurus, archaeologists have found fish, birds, amphibians and other animal fossils here, and there are many pterosaur fossils, archaeologists agree that this place was once one of the most important living areas for dinosaurs.
It is worth mentioning that in 2006, archaeologists also discovered a completely new dinosaur breed in Brazil, its name is "MaxacarliSolus Topai", which is a dinosaur from the late Cretaceous period, appeared on the earth about 80 million years ago, and is also one of the largest herbivores in the history of the earth.
"Mascia calis solos Topai" belongs to the range of thunderosaurs, its body length is more than 13 meters, its weight is a staggering 9 tons, it is also one of the largest dinosaurs found in brazil. Comparing the Alatarosaurus found this time, a significant difference in body size can be seen. So, which kind of dinosaur category does Aratadosaurus belong to?
Archaeologists call Ala tarrone's relatives in China
In 2001, in the Colorful Bay area of Xinjiang, Archaeologists discovered a new dinosaur species, its name is "Xinjiang Left Dragon", it belongs to the virtual bone dragon class, belongs to the theropod suborder, the dinosaur family is very well-known dinosaur species - Tyrannosaurus rex, belongs to the same category.
Archaeologists say that Xinjiang Zuolong comes from the Jurassic period, it appeared on the earth 160 million years ago, its body in the dinosaur team also belongs to the small body, the adult body length is about 4 meters, the weight is about 400 pounds. The Alatalong found in Brazil this time has a size, length and weight comparable to that of Xinjiang Zuolong, and archaeologists believe that there is a certain relationship between them.
This means that they may have all had the same ancestor in the early days of dinosaurs, but later evolved and split into different species. In the case of Xinjiang Zuolong, archaeologists believe that The Xinjiang Zuolong and the Tugulu dragon discovered in the Junggar Basin of Xinjiang in 1973 were once the same ancestor, and the Tugulu dragon appeared later than the Xinjiang Zuolong, which, like the Alatalong, came from the early Cretaceous Period.
However, there is also a problem here, that is, whether it is Xinjiang Zuolong or Tugululong, the places they found are in the Xinjiang region of China, if Alatalong and they were once the same ancestor, then why is Alatalong located in Brazil in South America?
Is Alataron a vegetarian or a carnivore?
As we mentioned above, the "big" dinosaur "Maxacarly Solus Topai", discovered in Brazil in 2006, was surprisingly tall but vegan, so was the same with Alatarosaurus? Archaeologists believe that Alataurus should belong to the same kind of virtual bone dragon as Therapidosaurus in Xinjiang, in short, theropod dinosaurs.
In the current study, the osteozoic dinosaurs are basically carnivores, they belong to the "advanced version" of the carnivorous dinosaurs in the evolutionary history of dinosaurs, they are smaller and more flexible, at the same time, they have longer forelimbs, and they have more advantages in predation.
Archaeologists say that Alatarosaurus should have fed on small mammals or insects, and they should have had primitive feathers on their bodies, which is also a common phenomenon in the evolution of osteotopheosaurus dinosaurs and one of their group characteristics. Next, archaeologists are ready to continue studying the relationship between Arataron and Xinjiang's Left Dragon, to trace the roots to see if they came from the same ancestor and, if so, how they traveled from Asia to South America.
