The descendants of dinosaurs are birds and some reptiles. Dinosaurs can be divided into birds and non-birds. Among them, non-avian dinosaurs lived only in the Triassic, Jurassic and Cretaceous periods of the Mesozoic Era, and all of them became extinct 65 million years ago.
The vigorous limbs, long tail, and huge body are portrayals of some non-avian dinosaurs. They mainly inhabit woodlands or open areas in lakeshore plains (or coastal plains).
Although dinosaur fossils have been on Earth for tens of millions of years, it was not until the 19th century that people knew that such a strange animal had ever existed on Earth. The first dinosaur fossil was discovered by a British physician named Gideon Mantel, who coined the term "dinosaur" by British paleontologist Richard Owen.
In 1842, the British paleontologist Sir Owen coined a name for them in Latin, which consisted of two roots. The former root means "horror" and the latter root means "lizard".
The ancestors of the dinosaurs.
After a long period of archaeological and fossil research, it was found that alveolar teeth were not only the ancestors of dinosaurs, but also the ancestors of most reptiles. The biggest difference between dinosaurs and other reptiles is the way they stand and walk. Dinosaurs can stand completely upright.
Dinosaurs mainly inhabited woodlands or open areas in lakeshore plains (or coastal plains).

The descendants of dinosaurs are birds and some reptiles, and dinosaurs can be divided into birds 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 muscular limbs, long tails, and massive bodies are some of the non-avian dinosaurs.
They mainly inhabit woodlands or open areas on lakeshore plains (or coastal plains).

After the disappearance of the dinosaurs, these three animals took the place of supremacy, and the last one may have offspring.

The scientific community generally believes that it was a bird, and the ancestor of the bird was Archaeopteryx, which was an intermediate transitional form between dinosaurs and birds, but only a small number of dinosaurs evolved into birds.
It is believed that the dinosaurs in some dinosaur-themed movies are imitated based on the appearance of birds.
Of course, reptiles such as lizards and crocodiles, as close relatives of dinosaurs, do not rule out inheriting a little dinosaur genes.

Dinosaurs are a large category, most of which died in the 6,500s, but a small number survived to the present.
According to the latest theory, dinosaurs did not end forever, but the evolutionary order was: Raptor-Microraptor-Millennial Chinese Birdcage-Chinese Ancient Thief Bird-Archaeopteryx-Bird.
So it can be said that the dinosaurs are not endless! You can check it out! You can also find that the evolution of birds began in China, and you can't underestimate the birds in the future! He's a descendant of dinosaurs!

The descendants of the dinosaurs are the present-day birds and some reptiles. 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), mainly inhabiting woodlands or open areas on the lakeshore plains (or coastal plains), and all of them became extinct 65 million years ago.
According to the definition given by the Chinese Paleontological Terminology Examination and Approval Committee, dinosaur refers to all the descendants of the nearest common ancestor of triceratops and modern birds, which have become extinct except for birds.
In 1841, when British scientist Richard Owen studied several fossils that looked like lizard bones, he thought they were left by some kind of prehistoric animal and named them dinosaurs.
The biggest difference between dinosaurs and other reptiles is the way they stand and the way they walk, dinosaurs have a completely upright posture and their limbs are built directly below their bodies.
-
There are only birds, and birds are direct descendants of dinosaurs, and crocodiles and lizards are at most distant relatives, because the ancestors of crocodiles and dinosaurs are species that live together, and there is no descendant relationship.
-
It's very simple, the descendants of dinosaurs are extremely terrifying, referred to as horror, the terrible thing is that dinosaurs no longer exist, and horror happens all around us all the time, such as ** mudslides, hostage-taking, plane crashes, etc., is that people can't overcome the sky, can't avoid it.
-
Dinosaurs are reptiles. The offspring that emerged after that were mammals. Such as: apes.
-
The dinosaurs are extinct, there are no descendants, only fossils.
-
It's dinosaurs, but they're all extinct!
-
It is currently believed that the descendants of dinosaurs were birds.
Birds evolved from a branch of dinosaurs, the chiraptors. Since the discovery of Archaeopteryx fossils in Europe, the idea that birds are descendants of dinosaurs has become popular. The successive discoveries of feathered dinosaurs in the Rehe biota in Liaoning Province have made it a fact that birds evolved from dinosaurs.
-
The common ancestor of dinosaurs and crocodiles is the dinosaur crocodile, after the separation of dinosaurs and crocodiles, the dinosaurs went extinct, but some dinosaurs evolved into birds. The crocodile survived and maintained its original basic form. And the lizard seems to have evolved from crocodiles, and then became snakes.
So snakes didn't evolve from dinosaurs. The descendants of dinosaurs are birds.
It is also possible that some aquatic dinosaurs survived and maintained their basic dragon form.
Turtles, on the other hand, evolved from the cup dragons.
Crocodiles are not descendants of dinosaurs (crocodiles appeared in the Mesozoic era from the Triassic to the Cretaceous, and were contemporaneous animals with dinosaurs, and the similarity may only be due to the influence of the bad environment of the times, so they are not considered descendants of dinosaurs in terms of origin), such as horned crocodiles are herbivorous creatures that lived in the late Triassic, and ground crocodiles are carnivorous creatures that lived in the middle of the Jurassic, all of which lived in the same era as dinosaurs.
There are many species of dinosaurs, and their biology can only be inferred from a limited number of fossils. Some scientists believe that at least some dinosaur species may have been homeothermics, and their reasoning is that some dinosaurs could move upright and move far from the ground, indicating that they no longer needed heat from the terrestrial environment; If they are ectotherms, then they should be able to regulate the metabolic level of the body and hibernate in areas with severe winter temperatures, but animals that are too large will encounter physiological insurmountable obstacles when hibernating; If dinosaurs and crocodiles were both ectotherms in terms of physiological mechanism, then there is no way to explain why the dinosaurs were all extinct while the crocodiles survived. >>>More

The largest dinosaur we've found so far is the Epitosaurus, which was 39 to 52 meters long! Heights can reach up to 18 meters!! The weight reached 130 tons.
Dinosaurs first appeared in the Triassic period about 240 million years ago and died out in the Cretaceous period about 65 million years ago during the late Cretaceous mass extinction event of the Mesozoic Era. The dinosaurs eventually became extinct 65 million years ago when an asteroid hit the Earth. >>>More
