What trivia do you know about dinosaurs? Let s talk

Most dinosaurs have feathers, and there should be very few people who know about this, and I once knew about it by chance.

Dinosaur trivia is that dinosaurs are very large, and sometimes they can hurt some other small animals.

Dinosaurs He was the first extinct animal in the world, although our generation has not seen real dinosaurs, but we have also seen them in the animal world, and they are very large animals.

Dinosaurs are very, very big, and stepping stones are very, very big, and can be preserved for a long time without breaking.

The trivia I know about dinosaurs is that they all eat meat and have very few herbivores.

The dinosaurs were very bizarre, and suddenly a large number of them were gone, which is a strange thing.

The hand of the bull dragon is actually the shortest, and the hand of the Tyrannosaurus rex is longer than that of a human.

I think dinosaurs are a very cold animal.

The knowledge that I know about dinosaurs is actually that dinosaurs are cold-blooded.

The dinosaurs seem to have come to the earth because of meteorites to blow up the earth and then destroy it.

My trivia about dinosaurs is actually that he's particularly powerful and heavi.

Trivia? Small dinosaurs account for more than 90% of the dinosaur species that have been discovered.

The largest dinosaurs were tens or even hundreds of tons.

Dinosaur meat is delicious, and I usually don't tell anyone about it.

Appearance characteristics of dinosaurs: Dinosaurs are large in size overall. By the standard of dinosaurs, sauropods are the giants of them.

During the long age of dinosaurs, even the smallest sauropods were larger than the other animals in their habitat, and the largest sauropods were several orders larger than any animal that appeared on the surface.

The smaller, fast-moving dinosaurs evolved a trait that can also be seen in modern animals: thin-walled bones. The bone resembles a hollow tube, with a thin outer wall made up of heavy bone, which is much lighter bone marrow.

Fast-moving herbivorous dinosaurs, such as Oak Tree Dragon, had this thin-walled long bone. We can assume that this skeleton is meant to reduce weight and thus gain greater speed when escaping from predators.

Growth and reproduction

Scientists have found not only the bones of dinosaurs, but also the nests and eggs they left behind. These dinosaurs were all small ceratosaurs, Protoceratosaurus. When alive, it was the size of a modern-day sheep.

Its eggs are cob-ovate, about 75 cm wide and 15 cm long, with up to 30 eggs, arranged in a spiral shape in the nest with the tip of the egg pointing inward.

The nest is located in a depression in the sand, as Protoceratosaurus lived in a sandy place. Many female dragons seem to lay eggs in the same set. By chance, in one of the nests, an egg-eating dinosaur was found, the fossilized skeleton of an egg-stealing dinosaur.

It seems that the animal was crushed to death by a sandstorm when it attacked the nest. Since then, eggs of many other species of dinosaurs have been discovered.

The word "dinosaur" refers to a dire lizard in the West, which was translated by Japanese paleontologists as "dinosaur", and later became popular in China. In the 19th century, people learned that such a strange animal once existed on the earth. The first dinosaur fossil was discovered by a British physician named Gideon Mantel.

Characteristics of dinosaurs.

The muscular limbs, long tails, and massive bodies are some of the non-avian dinosaurs. They mainly inhabit woodlands or open areas on lakeshore plains (or coastal plains).

Dinosaurs evolved from amphibians. There are two main aspects of evolution: one is the respiratory system, and the other is the reproductive system.

Dinosaurs can be divided into avian and non-avian dinosaurs. Among them, non-avian dinosaurs lived only in the Mesozoic era (Triassic, Jurassic and Cretaceous) and were all extinct 65 million years ago.

1. Dinosaurs are a general term for a class of reptiles that appeared in the Mesozoic Era, and their vigorous limbs, long tails and huge bodies are the portrayals of most dinosaurs. They mainly inhabit woodlands or open areas on lakeshore plains.

When British scientist Richard Owen studied several fossilized lizard bones, he thought they were left by some prehistoric animal and named them dinosaurs, which means "terrifying lizards". The dinosaurs suddenly disappeared at the end of the Cretaceous period 65 million years ago, becoming a mystery in the history of the evolution of life on Earth, which is still unsolved. All of the earth's past creatures are recorded in fossils.

In the strata of the Mesozoic era, many dinosaur fossils have been found.

3. A large number of bones or various shapes can be seen. However, in the Cenozoic strata that followed, there were no fossils of non-avian dinosaurs at all, which suggests that non-avian dinosaurs became extinct together during the Mesozoic Era, and that only birds remain today, and most scientists agree that "birds belong to dinosaurs".
