What is a dinosaur, as the title says, thank you

It depends on what you're talking about, if it's a creature, then a dinosaur is a very large animal that lived in the Cretaceous era, and if someone says something about a dinosaur, then it means that it's the kind of person who looks very sorry for the audience, and the body is ugly.

Dinosaurs are just a noun, in fact, they are synonymous with those reptiles who once dominated the earth, most of the animals on the earth in that period were dinosaurs, they were huge and agile, but they consumed too much space on the earth, had no intelligence, and could not create, so they became extinct.

Dinosaurs are also a creature, and the earth is richer with him, because he is a very smart behemoth, because she is too handsome, and the world does not allow him to live, so the dinosaurs are extinct.

Biological dinosaurs refer to giant reptiles that appeared 100 million years ago. Real-life dinosaurs refer to scary people (Internet terminology especially refers to ugly girls).

The oldest reptile fossils date back to the Paleozoic Pennsylvania (10,000 years ago). Tracing back to its origins, it evolved from amphibians. Amphibian eggs need to be able to develop in water.

Reptiles have evolved egg shells that prevent water from escaping. This major reform allowed reptiles to live out of the water. In the Mesozoic Era, from 10,000 years ago to 10,000 years ago, reptiles became the rulers of the earth, so the Mesozoic Era is also known as the era of reptiles.

Large reptilian dinosaurs appeared in the early Mesozoic Era. Herbivorous Diplodocus and Brontosaurus were the largest terrestrial animals. Tyrannosaurus rex was a carnivorous dinosaur.

There are also ichthyosaurs that live in the sea and pterosaurs that live in the air. Reptiles have flourished on the earth for about 100 million years or so. Among the animals of this era, the most well-known are dinosaurs.

When people think of dinosaurs, they will see a huge and ferocious animal, but in fact, there are also small and tame dinosaurs. Dinosaurs are vertebrate reptiles, which were once found in terrestrial swamps in the Mesozoic Era, with a long neck and tail. The hind limbs are longer than the forelimbs and have tails.

Among them, there are several good carnivorous species, several good herbivores, and their bodies are huge, and they can be considered the largest of the terrestrial animals. Its physique is inferior to that of crocodiles and beaks, and it is slightly similar to birds in the higher species. The study of dinosaurs is all about fossils.

Paleontologists use their fossils to infer their morphology and habits. According to paleontologists, dinosaurs were like living animals: some were big and some were small; Some walk on two legs; Some walk on four legs; Some eat plants, some eat animals; Some **smooth, some** have scales or bony plates.

The common similarities are that all dinosaurs had small brains and laid eggs on land (as is the case with all reptiles). Dinosaurs were Mesozoic reptiles that appeared 245 million years ago and flourished 65 million years ago.

Or a vague general term for dinosaurs and their contemporaries, plesiosaurs, pterosaurs, etc. The sudden disappearance of the dinosaurs at the end of the Cretaceous period 65 million years ago has become a mystery in the history of the evolution of life on Earth, which is still unsolved.

Dinosaurs were animals that dropped in ancient times.

Dinosaur is a general term for a group of reptiles that appeared during the Mesozoic era (Triassic, Jurassic and Cretaceous), with vigorous limbs, long tails and large bodies that are portrayed by most dinosaurs. They mainly inhabit woodlands or open areas on lakeshore plains (or coastal plains).

The dinosaurs suddenly disappeared at the end of the Cretaceous period 65 million years ago, becoming a mystery in the history of the evolution of life on Earth, which is still unsolved. All of the earth's past creatures are recorded in fossils.

In the strata of the Mesozoic era, many dinosaur fossils have been found. A large number of bones can be seen in a variety of shapes. However, in the Cenozoic strata that followed, there were no fossils of non-avian dinosaurs at all, which suggests that non-avian dinosaurs became extinct together during the Mesozoic Era, and that only birds remain today, and most scientists agree that "birds belong to dinosaurs".

Is it the green one, maybe the Brontosaurus?

Socrocodilusaurus (genus name: Suchomimus) means "crocodile mimic", a large dinosaur of the Spinosauridae family with a crocodile-like mouth, which lived in Africa during the Middle Cretaceous period, about 120 million to 110 million years ago. Crocodile dragons belong to theropods.

Much like living crocodiles, they named the fossil after the shape of the fossil's head, and the type species, Tenelle, resembles a crocodile.

Dinosaur name: crocodile-like.

Latin name: Suchomimus Teneresis

Dinosaur body length: 12 meters long, 12 meters high.

Dinosaur weight: 7 tons.

Age of existence: Early Cretaceous.

Location: Niger, Africa.

Dinosaur species: sauropods, theropods.

Dinosaur food: Meat, fish.

Crocodile (genus name: Suchomimus) means "crocodile mimic" and is a large dinosaur of the Spinosauridae family.

Identification tips: thin body, low and long skull, short legs, thin proportions of skull, narrow mouth proportions, very straight teeth, large number of teeth, low sail on the back.

Feeding on fish, the body length is about 10 meters, crocodile is a dinosaur with a longer nose than the clawed dragon, and the front of the mouth is also curved and hooked, and it is also one of the fishing experts in the spinosauridae.

Crocodile-like, looks like a Tyrannosaurus rex or Spinosaurus, but she does not belong to the two dinosaurs, belongs to the crocodile, has a body length of 12 meters and weighs 9 tons.

Yanmei Taoist Mountain House (Meng Haoran).

Prototype: Double-crested dragon, spine-backed dragon, avian dragon.

Scientific name. Dilophosauridae Dilophosauridae Dilophosaurus is an extinct reptile of the sauropods

The body is relatively stout, the skull is tall, the jawbone is well developed, the mouth is large and the mouth is full of teeth like sharp knives, and there are small serrations on the front and rear edges of the teeth, which show that it can tear apart any prey it catches, and then swallow large pieces of meat into its belly. In addition, the skull of the Dilophosaurus had holes in the back of the eyes, which were used to better attach to the muscles that pull the jawbone, so the bite of the Dilophosaurus must have been very powerful. Scientists speculate that Dilophosaurus may have been the most brutal and ferocious carnivore in the early Jurassic ecosystem.

For example, Post's crocodile is a hybrid that looks like a crocodile and a Tyrannosaurus rex, and has a general length, mainly a huge skull.

The Post crocodile is a giant protosaurus native to Texas, Arizona, and New Mexico, named after the Texas town of Post. From the restoration map, Poste crocodile. With a body length of 6 meters and a tall, huge skull, the Post crocodile appeared to be a fearsome predator capable of catching and killing most of the large animals of the time.
