Of course, there are no real dinosaurs, and some books write fake stories about who saw dinosaurs for the sake of consumption. It's more annoying. It's like the 100,000 whys of some aliens. Misleading!

Yes....Both Juxi and Crocodile can be said to be.

There really were dinosaurs in the world.
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 63 million years ago (at the end of the Cretaceous period and the beginning of the Tertiary period) has become a mystery in the history of the evolution of life on Earth, a mystery that no one has solved to this day.
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 dinosaur fossils at all. It is inferred that the dinosaurs became extinct together during the Mesozoic Era.
The latest research suggests that a small percentage of dinosaurs may have survived that mass extinction. In the end, it became extinct because it did not adapt to the cold and dry climate.
Body shape characteristics of dinosaurs
Dinosaurs were large in size overall. By the standard of dinosaurs, sauropods are the giants of them. During the long age of dinosaurs, even the smallest sauropods were larger than the other animals in their habitat, and the largest sauropods were several orders larger than any animal that appeared on the surface.
Most dinosaurs were much smaller than large sauropods. The available evidence suggests that the average size of dinosaurs varied throughout the Triassic, Early Jurassic, Late Jurassic, and Cretaceous periods. Most theropods weighed between 100 and 1,000 kilograms, while predatory carnivores in the Holocene were mostly between 10 and 100 kilograms.
Dinosaur weight estimates are mostly between 1 and 10 tons. According to a study by the National Museum of Natural History in London, the average weight of dinosaurs was about 100 kilograms, while the average weight of Cenozoic mammals was between 2 and 5 kilograms.

Some. Dinosaurs were Mesozoic road-dwelling reptiles that appeared 245 million years ago and flourished 65 million years ago. 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 dinosaur fossils at all, which suggests that the dinosaurs became extinct together during the Mesozoic Era. There are many types of dinosaurs, and their body shape and habits are also very different. The largest of them can be as large as dozens of elephants combined; It's small, but it's about the same as a chicken.
In terms of eating habits, there are docile herbivores and ferocious meat eaters, as well as omnivorous dinosaurs that eat both meat and vegetables.
A dinosaur fossil was discovered between 2006 and 2012 in Nakhon Ratchasima, northeastern Thailand, dating back about 100 million years. The fossils have been identified as belonging to a new species of avianthosaurs. Ornithosaurs were very common herbivorous dinosaurs during the Cretaceous period (about 100 million to 66 million years ago).
This dinosaur was named "Sirindhorn". Thank you for adopting.

There are dinosaur fossils and dinosaur egg fossils. There are also fossilized footprints. Appeared 230 million years ago and reigned as the master of the earth.

Yes, this is based on historical and practical evidence. Dinosaur fossils are proof of their existence.
The extinction of the dinosaurs was linked to the impact of a comet on Earth. 65 million years ago, a comet crashed into the earth, it immediately turned the surrounding sea water into steam and expanded violently, forming a tsunami wave tens of meters high and a powerful shock wave, and the plants near the ocean were either swept away by the waves or were killed by the shock wave. >>>More
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.
Let me put it this way, since elementary school, there are a lot of people who fall in love, and most of the people who have crushes in elementary school students are boys, and boys like girls who are good in their class, and girls like boys who are good in class, but because of their young age, and because they are reserved, they generally don't express their thoughts, so most of them have secret loves, and they don't understand that they only admire each other. >>>More

A hair transplant can achieve a one-and-done effect.
Hair transplantation is a process in which the healthy and long-lived hair follicles in the posterior occipital region are used as donor resources, which are extracted and then separated, cultivated and then planted in the area of hair loss. >>>More
