#Dinosaurs #educationalvideos #VideosForKids ⭐ SUBSCRIBE TO THE MOTAS CLUB⏩ https://tinyurl.com/ydfz3q6f ????We will tell you the history of the Dinosaurs and why they no longer exist today. We have known of their existence through various movies or maybe it is your favorite toy, right? According to several years of research, it is known that the first dinosaurs appeared 254 million years ago, at that time there was a single continent and it was called Pangea, yes we are talking about thousands and thousands of years ago, Pangea was divided causing the dinosaurs to separate, and they adapted to their new habitat and at the same time new species were created. According to studies, there were more than 1,000 species of dinosaurs. Wow, that was a lot of Motas. We must know that the size of these species varied greatly. The smallest species discovered measured almost the same as a chicken and the largest measured 26 meters, could reach a height similar to the seventh floor of a building, and weighed 59,000 kg. Did you know that there were carnivorous and herbivorous dinosaurs? Carnivorous dinosaurs are those that fed on other animals, while herbivorous dinosaurs fed only on plants. Almost 40% of species were carnivorous. Scientists divide dinosaurs into two large groups according to their hips. The Saurischians are the group whose hips are similar to those of lizards, while the Ornithischians have hips similar to those of birds. How about we look at some of the most famous dinosaurs? In movies like Jurassic Park or Jurassic World, the most famous carnivorous dinosaur, the Tyrannosaurus Rex, appears. It fed on other animals, it was about 15 meters long and weighed the same as three elephants, its teeth measured 33 centimeters and were very sharp and pointy, it was an agile and strong animal. And it was one of the most dangerous dinosaurs that have ever existed. On the other hand, there is the diplodocus, the largest dinosaur in the world measured almost 26 meters, its neck measured 8 meters and its tail reached 14 meters, the tail of the diplodocus was always up and helped as a counterweight to its enormous neck, it used its tail to hit its predators, but if it hit the ground it makes a sound like a cannon shot. Another dinosaur was the Triceratops, one of the best known, it had a large head with large, long horns, it had a crown-shaped armor that protected its weak points, such as the neck. Its head was so big that it weighed the same as a car, it had three horns, two large ones on its extremities and a smaller one on top of its snout, and it also had 432 teeth. If one of them broke, another one grew in its place. It is believed that the size of the horns also served to conquer the female triceratops, it was a very strong animal and did not give in to its predators, it even faced the feared tyrannosaurus rex. Another great dinosaur was the iguanodon, it was the size of an elephant, it walked on all four legs, but it was able to stand up on its hind legs and run very fast. Wow Motas what incredible animals they were, but why they became extinct Nata the exact reason remains a mystery, but according to many years of research, the most logical reason was the impact of an asteroid. If 66 million years ago an asteroid more than 9 kilometers wide fell on Earth, destroying a large part of it. The asteroid caused many changes on the planet, creating forest fires, volcanic eruptions and gases that caused sudden changes in the climate, leading to the extinction of about 75% of all species. Although most of the dinosaurs disappeared, several species survived and some evolved into the birds we see today. If birds are the closest animals to dinosaurs, incredible right? Wow, what an incredible evolution, but Motas if human beings did not exist, how do we know so much about them? The existence of dinosaurs was determined from the discovery of thousands of fossils that paleontologists found in their different and large investigations. It has also been known that crocodiles, turtles, sharks, bees and starfish lived with dinosaurs and are animals that managed to adapt to the changes generated by the asteroid. How interesting it is to be a paleontologist, you can discover a lot about the past of our planet. Motas and could we know what would have happened if the dinosaurs had not become extinct? A study conducted by some researchers has determined that dinosaurs would continue to be the dominant animal species on earth, since dinosaurs lived on earth for 140 million years and humans have lived for 200 thousand years. ⭐ SUBSCRIBE TO THE MOTAS CLUB ⏩ https://tinyurl.com/ydfz3q6f
