1. Dinosaurs aren’t the first reptiles

It’s already mentioned that dinosaurs existed around 23 million years ago. Even though,  there was a reptile species named ‘Archosaurs’ and ‘Therapsides’ before dinosaurs. And, these reptiles had supreme dominion over earth whereas dinosaurs became extremely dominant only by the beginning of the Jurassic era.

2. Undiscovered dinosaurs

 All the scientific information related to them is acquired from fossils. As a part of it, more than 1000 varieties of dinosaurs are discovered but they are only the varieties that lived 65-150 million years before. Still, much more information and evidence from different continents remain concealed, so there would be many more varieties of dinosaurs that aren’t even named.

3. Incredible life span

Human beings always consider themselves as the supreme creation in this universe, although human history only began 10000 years ago. But, dinosaurs enthroned for around 150 million years and they were one among the creatures that lived long in this world.

4. Types of Dinosaurs

Dinosaurs are widely differentiated into two:- Saurischian and Ornithischian and this classification are based on their body structure. Saurischians are omnivorous and they are similar to lizards whereas the latter are herbivorous and like birds. Surprisingly, birds evolved not from Ornithischian but the lizard-shaped Saurischians.

5. Predecessor of birds

The majority of the scientists and scientific studies claim that birds evolved from the small-sized dinosaurs with flapper that existed during the Jurassic and Cretaceous. Modern birds are descended from the two-legged dinosaur species ' Theropods. However, birds are considered as living dinosaurs claiming that they’re not related to dinosaurs, they are dinosaurs.

6. Warm-blooded Dinosaurs

 Reptiles are cold-blooded and their body temperature varies according to their surroundings. This is a common feature of reptiles, but some dinosaur varieties were not like that. Studies assert that some predator dinosaurs were warm-blooded like mammals because cold-blooded creatures can’t have an active lifestyle with predatory behavior.

7. Pure vegetarian Dinosaurs

It’s a natural law that herbivores are more numerous than carnivores and likewise, most of the dinosaurs were poor vegetarians who didn’t make any hurt other creatures.  Hence the herbivorous Hadrosaurus, Ornithopod dinosaurs, Sauropods in the Mesozoic era were more in number than the flesh-eating Theropod dinosaurs.

8. Intellectual of Dinosaurs

 Ironically, these gigantic beasts had a brain like an egg, so they’re even less intelligent. To be precise, their brilliance was little more than that of plants. But, when it comes to Carnivorous dinosaurs, they had high sensations and thus greater intellect. Even though, it’s surprising that the brighter ones among the dinosaurs only had the brilliance like an ostrich.

9. Did Dinosaurs precede Mammals?

Everyone thinks that dinosaurs emerged before mammals but it is an incorrect statement that dinosaurs preceded mammals. The earliest mammals lived even during the time of dinosaurs and they were only having the size of rats. To save themselves from the grip of dinosaurs, these tiny mammals remained in the branches of tall trees.

10. Were Dinosaurs able to swim?

 We all have seen in flicks that some dinosaurs were able to swim and remain inland. Technically, they weren’t dinosaurs because dinosaurs are considered by the scientists as reptiles that are having different body structures and only remain in the land. Hence, the beasts like Pterosaurs( that can fly), Plesiosaurs, Ichthyosaurus( that can swim) are not dinosaurs. Studies assert that they aren’t even related to dinosaurs and the only equivalent element is that they’re reptiles.
