What are the natural enemies of dinosaurs, please 3Q

Chinese and American archaeologists reported in the British journal Nature that they had found fossils of a large mammal that lived in the Mesozoic era during an archaeological excavation inside China. They studied it and speculated that the newly discovered animal probably fed on dinosaurs of the same era. Hu Yaoming, Wang Yuanqing, Li Chuankui of the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences, and archaeologists from the New York Museum of Natural History in the United States said in the report that the mammal fossil they found in Liaoning Province dates back to 100 million years ago and is well preserved.

The animal is more than a meter long and weighs an estimated amount of between kilograms. Judging by its skeletal structure, it is sturdy and capable of pounceing on prey, but is not good at long-distance running. Archaeologists named the newly discovered animal the giant reptile.

In the report, archaeologists noted that the discovery of the fossil shattered previous understanding of Mesozoic mammals. Previously, scientists thought that due to the dominance of the Mesozoic dinosaurs, mammals at that time should have been very small. It was only after the extinction of the dinosaurs 10,000 years ago that large mammals appeared.

One of the more interesting discoveries in this archaeological study is that archaeologists have found a strong reptile fossil at the same time as the giant reptile fossil. And in the stomach of this strong reptile fossil, there are the bones of some pstucid of the psittacosaurus. The psittacosaurus cubs found were only to centimeters long, while the strong reptiles that prey on it were twice as long.

Archaeologists theorized that the strong reptiles were likely to have taken the Psittacosaurus as their "early". If strong reptiles were able to prey on dinosaurs, it is likely that the newly discovered giant reptiles were also preying on dinosaurs.

The natural predator of dinosaurs was natural disasters.

In the age of dinosaurs, the natural enemies of dinosaurs were dinosaurs.

Dinosaurs are also divided into herbivorous dinosaurs and carnivorous dinosaurs, for example, like Tyrannosaurus rex is a very best carnivore, according to modern archaeological analysis, Tyrannosaurus rex legs are powerful and good at running, sharp teeth can bite bones is the top of the food chain dinosaurs at that time, Tyrannosaurus rex is a herbivorous dinosaur for food. The three major natural enemies of Tyrannosaurus rex were Spinosaurus, Saterssaurus, and Aeolian Pterodactyl. Tyrannosaurus rex survived at the end of the Cretaceous period, with a body length of 11-15 meters, a weight of 9-15 tons, and a strong body with a strong head and hind limbs.

Dinosaurs, referring to the Triceratops, the most recent common ancestor of modern Luchang birds and Diplodocus and all their descendants. To facilitate research, dinosaurs can be divided into avian and non-avian dinosaurs. Among them, non-avian dinosaurs lived only in the Mesozoic era (Triassic, Jurassic and Cretaceous) and were all extinct 65 million years ago.

The habits of dinosaurs

1. Herbivorous.

Dinosaurs were limited by their height, so some small herbivorous dinosaurs would stand on their hind legs in order to eat the leaves of plants at high heights. Carnivorous dinosaurs fed on herbivorous dinosaurs and other animals. The different foraging patterns of various dinosaurs are also reflected in their teeth.

2. Struggle. Sharp teeth and claws are carnivorous and poor old dinosaurs. Tyrannosaurus dinosaurs often went it alone because they sought out lone herbivorous dinosaurs.

Some dinosaurs would move in groups, locking on to their prey and swarming and slicing open the prey's abdomen with the second finger of their claws. Inflated.

Herbivorous dinosaurs generally had some special "equipment" to deal with the attacks of carnivorous dinosaurs, which sometimes consisted of tough leather armor, bone clubs, or bone spikes, and sometimes powerful tails. Such as mallet dragon and so on. Large herbivorous dinosaurs would act in groups, and when threatened, they would collectively hold their ground and fight back.

Far in space, two huge asteroids collided unwillingly, and the larger fragments of Batistina collided head-on with Earth, resulting in the complete extinction of the dinosaurs. Experts say that 100 million years ago, dinosaurs suffered a less complete extinction event, is it a little distressing for dinosaurs?
