Dinosaur commentary composition

Everyone has tried to write a composition in our daily study, work and life. The composition must be elaborated around the theme and the same theme. Don't ramble, the theme is lax or even without a theme. Then the question comes, how to write an excellent composition? The following is my dinosaur essay for your reference, hoping to help friends in need.

Some people say that dinosaurs are the most prehistoric creatures. No, the beginning of life is fungi. Dinosaurs are the largest known prehistoric creatures on land.

Dinosaurs evolved from scale lizards, which were the first generation of reptiles. There are only plants on the earth, so carnivorous dinosaurs tried to kill other herbivorous dinosaurs because they didn't adapt. When they found it just right, the classification of dinosaurs gradually evolved.

The most accurate classification of dinosaurs should be: terrestrial habitats and marine habitats. There are more than 20xx species on land, but there are only five kinds of dinosaurs in the sea!

If a big dragon opens its mouth, an adult can barely touch its gums by raising his hand. Carnivorous dinosaurs hunted like this: they hunted alone, biting their prey first, and then slowing down to catch up. The prey fell down because of excessive blood loss. They bit off its neck and enjoyed it slowly. Compared with dragons, dragons are just the opposite. They are too small to hunt alone, so they chase their prey in groups.

All living things in the world have biological clocks, and dinosaurs are no exception. Herbivorous dinosaurs were active during the day and slept at night. Carnivorous dinosaurs came out at night and day.

All dragons lay eggs, and dinosaur eggs can be broken after several months of gestation, and a small life is born.

However, the myth of dinosaurs did not last. It is said that an asteroid as big as the center of the earth hit the earth and the dinosaurs became extinct.

The study of dinosaurs has never stopped. I hope you can explore more and learn more about dinosaurs.

Dinosaur is a terrible animal, but are there any lovely dinosaurs? Hee hee, the answer is-yes!

The first type: "Ningcheng Shuxilong". Place of birth: Inner Mongolia. Height: poor! Only 20 centimeters. Home: a tree. Race: theropod dinosaurs climb dragons.

The second type: "Hu". Birthplace: Like Ningcheng Shuxilong, it is also in Inner Mongolia. Height: only 25 cm, shorty! Weight: Short people are still a little fat, about 80 kg. Tail feather: It's about the same length as height, 20 cm long! It is really long.

The third kind: "distant little red dragon". Place of birth: Mongolia. Height: The height is only 40 cm. The forelimbs are short, and the second and third fingers are degenerated. Main food: termites.

I learned three lovely dinosaurs. Let's talk about the dinosaur school first! Dinosaurs were born in Mesozoic (Triassic, Jurassic and Cretaceous). Most of them have vigorous limbs, long tails and huge bodies. Mainly living in forests, beaches, plains and other places. "Terrible lizard" is their nickname. For herbivorous dinosaurs, strength is the lifeblood, so their legs are big and strong. Their weight is between 100- 1000 kg, alas, it is too heavy! Want to lose weight! Their "father" long-necked dragon, tall and strong, was born in Tanzania. It is 12 meter high, 23 meters long and weighs 50 tons. This is a six-story building! The longest dinosaur is Liang Long, 27 meters long!

Hee hee, dinosaur fans, don't thank me for giving you "missing questions"!
