About 200 million years ago, geological history began to enter the Mesozoic Era. At this time, dinosaurs appeared on the earth. Over the next 100 million years, the dinosaur family grew larger and larger. Later, they seemed to suddenly disappear completely within a day, leaving us with countless mysteries.
After the unremitting exploration of scientists, we gradually gained some understanding of dinosaurs. It turns out that although dinosaurs are big, stupid and scary, their stories are actually quite interesting.
The story of the Mother Dragon: In the past, people always believed that dinosaurs, like reptiles today, just walked away as soon as they laid eggs, regardless of what would happen to their children. Later, scientists discovered that the teeth of some young dinosaur fossils had obvious signs of wear, indicating that it had begun to eat.
However, the limbs of these young dragons are not fully developed, and they have obviously not begun to crawl in the true sense. It seems that the young dragons are raised by their parents in the nest. In addition, analysis of dinosaur footprint fossils shows that they often went out in formations, with large dinosaurs on both sides and small dinosaurs in the middle, just like the elephants we see today.
So scientists gave this dinosaur a very humane name, Matrosaurus. However, many people believe that this evidence alone does not prove that dinosaurs raised their offspring with purpose. For no reptile in the world now shows such love.
Crocodiles are the best at what they do. They just pick up the newly hatched baby crocodiles in their mouths and bring them to the water. Even if the task is completed, as for whether the baby crocodiles can swim, they can It doesn't care if it can't prey. The merosaurus can lay 25 eggs each time. These 25 little dinosaurs eat hundreds of kilograms of fresh and tender plants every day. The merosaurus needs to work tirelessly everywhere to find food.
Extended information:
The word "dinosaur" refers to dino lizards (terrible lizards) in the West. Japanese paleontologists translated it as "terrible dragons" and later became popular in China. The ancient Greek word Saurosc refers specifically to some huge lizard-like reptiles with limbs and tails or wings. ?
The "dragon" in this context of Eastern translation specifically refers to the Greek lizard family, such as Archosaurus, Tyrannosaurus, Dimetrodon, Diplodocus, Tyrannosaurus Rex, Pterosaurus, Triceratops, etc. . Just like the word "tiger" in "gecko", it is a transfer character. ?
Although dinosaur fossils have existed on the earth for tens of millions of years, it was not until the 19th century that people knew that such strange animals had ever existed on the earth. The first person to discover dinosaur fossils was a British physician named Gideon Mantel, and the person who coined the term "dinosaur" was British paleontologist Chad Owen.?
