Dinosaurs was one of the most successful animals in terms of longevity that have ever lived on this earth. They were generally found into many diverse shapes and sizes.The word dinosaurs were design by sir Richard Owen in 1842 to explain these fearful animals. Particularly Megalosaurus, Iguanodon and Hylaeosaurus, the only three dinosaurs known at that time. The animals generally we think of as dinosaurs lived during the period of Triassic about 225 million years ago and the end of these creatures about 65 million years ago. But we know somewhere they actually live as the birds.
Misconception about the dinosaurs:
Not everything huge and dead is a dinosaur. We often see in books, movies and through some others medium authors or directors trying to add such animals for their popular audience. Dianosaurs is a group of aquatic and land animals that includes crocodiles, pterosaurs and birds. Though pterosaurs are lookalike dinosaurs but they are not actual dinosaurs. Even aquatic animals are faraway related to dinosaurs, which include the plesiosauras and ichthyosaurs. Godzilla and rhinoceros is creature and didnt appear until millions of years after the end of cretaceous period. Some animals are neither a reptile nor a mammal such as Dimetrodon.
All dinosaurs didnt live at the same time Different types of dinosaurs lived at different yeras. We have seen Jurassic park, King Kong and some other movies where dinosaurs were described briefly, despite the likeness or copy in the movies no stegosaurus ever saw a tyrannosaurus, because it not appeared on the scene until 80 and same goes for Apatosaurus-its bone were well solid by the time.
Dinosaurs are not died. Technically, scientists are discovered that dinosaurs are not died. This evidence they have got after the research of dinosaurs skeleton and they are considering that dinosaurs are alive in the form of birds. This shocking information makes a person to imagine a small moving bird as a authentic dinosaurs. So rather than mention to “dinosaurs” and birds as separate, individual groups. It would be best to mention to the traditional, dead animals as “non air borne dinosaurs” and birds as, well, birds or air borne dinosaurs. It would be wrong to say that dinosaurs are completely disappeared. They have left living childrens in the form of small mammals and their friends-just like wild things are still mammals .
How the existence of the dinosaurs were finish. There are various theories to explain how they became extinct he unusually large extinction at the end of the cretaceous period. There is now global evidence that there is a comet impact or falling star impact may be the reason of extinction. We can see this impact on most of the planets in our solar system. A visible example of this was noticed in 1994, when Jupiter was struck with the falling stars and blasted larger than the earths diameter. Other factors may be thorough release of volcanic gases, climate cooling, sea level changes, poison gases from the blasts or changes in the earths orbit or magnetic field may have donated to this extinction occurrence.
