1. Birds in the world today evolved in the age of dinosaurs. The scientific community generally believes that dinosaurs are the ancestors of birds, and many dinosaurs themselves also had feathers.

     2. At the same time, dinosaurs also have a relatively close "blood relationship" with modern crocodiles and lizards.


     3. In some film and television scenes, the overlord attacks the stegosaurus. In fact, this is impossible. According to archaeological data, Stegosaurus was already extinct when Tyrannosaurus Rex appeared.


     4. In fact, in the 160 million-year history of dinosaurs, Tyrannosaurus rex only existed for the last 3.5 million years...


     5. Stegosaurus is 9 meters long and over 3 meters tall. However, its brain is only as big as a walnut...


     6. The so-called Tyrannosaurus is actually Tyrannosaurus Rex, whose scientific name is Tyrannosaurus Rex.


     7. Although pterosaurs have the word dragon and lived in the age of dinosaurs, they are not dinosaurs in terms of biological classification.


  Archaeologists have unearthed incomplete fossils of Amphelophyllosaurus. Based on proportions, its body length may even have reached 58 meters. If this speculation is accurate, it could even weigh up to 220 tons, exceeding the limit of a blue whale.


     9. The smallest dinosaur discovered by humans is called Leptognathus, which is only the size of a turkey and weighs only 3 kilograms. It is considered to be the ancestor of Archaeopteryx. It seems that the weight difference between the largest dinosaur and the smallest dinosaur may be 700,000 times!


     10. The cause of the extinction of the dinosaurs is still in doubt, and an asteroid impact is only the most likely hypothesis. One hypothesis is that the farts of dinosaurs contained a lot of gases that seriously polluted the environment, causing the destruction of the ecosystem, which in turn caused the dinosaurs to lose their living environment.
