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

2. At the same time, dinosaurs and modern crocodiles and lizards also have a relatively close "blood relationship".
3. Some movies and TV shows depict Tyrannosaurus Rex attacking Stegosaurus, but this is impossible. According to archaeological data, Stegosaurus was already extinct when Tyrannosaurus Rex appeared.
4. In fact, of the 160 million-year history of dinosaurs, Tyrannosaurus Rex only existed for the last 3.5 million years...
5. A Stegosaurus could reach 9 meters in length and over 3 meters in height, yet its brain was only the size of a walnut…
6. The so-called Tyrannosaurus Rex is actually a Tyrannosaurus Rex, scientifically known as Tyrannosaurus Rex.
7. Although pterosaurs have the word "dragon" in their name and lived during the dinosaur era, they are not dinosaurs from a biological classification perspective.
8. Amphicoelias fragillimus is the largest dinosaur discovered to date, and possibly the largest animal to ever exist on Earth. Archaeologists have unearthed incomplete fossils of Amphicoelias fragillimus, and based on scale, its length could have reached 58 meters. If this estimate is accurate, it could have weighed up to 220 tons, exceeding the weight of a blue whale.
9. The smallest dinosaur discovered by humans is called Compsognathus, which was only the size of a turkey and weighed just 3 kilograms. It is considered to be the ancestor of Archaeopteryx. Therefore, the weight difference between the largest and smallest dinosaurs could be as great as 700,000 times!
10. The cause of dinosaur extinction remains uncertain, with asteroid impact being the most likely hypothesis. One hypothesis suggests that dinosaur farts contained a lot of gases that severely polluted the environment, destroying the ecosystem and causing the dinosaurs to lose their habitat.
