What are the ancient animals, what are the ancient animals, what are the ancient animals

1. Ancient animals include trilobites, dinosaurs, mammoths, hydrosaurs, Archaeopteryx, stone-clawed beasts, armored fish, etc. Prehistoric organisms are the many organisms that lived on Earth, dating from about 3.8 billion years ago to about 3500 B.C., before humans began to keep written records.

2. The types of prehistoric organisms include bacteria-like cellular organisms in the ocean, algae and protists, and more complex eukaryotic multicellular organisms, such as fungi, plants, mollusks, etc. 300 million years before humans walked upright, reptilian dinosaurs were the overlords of the planet, some of them evolving into the largest land animals ever built, others savage predators. The supremacy of the dinosaurs ended 65 million years ago.

Some scientists speculate that an asteroid hit the Earth at that time and caused the extinction of the dinosaurs. In the years since, mammals have ruled the planet and evolved many wonderful species, including us humans.

We know that the largest animal is a whale, but who would it be in ancient times?

It is the largest ancient animal

The largest dinosaur we've found so far is the Epitosaurus, which was 39 to 52 meters long! Heights can reach up to 18 meters! The weight reaches 130 tons!

In other words, 2 to 3 vibrators stand together and line up from one gate to the other in the football field. And if such a heavy behemoth walks on the field, its huge feet will make the earth tremble every time it steps on the ground, just like **. This is the meaning of the name "Zhenlong".

Shock Dragon

The age of the earthquake dragon lived was about 162 million years ago to 136 million years ago in the late Jurassic period. Taxonomically, it belongs to the sauropods, sauropods, and diplodocids. In addition to the Episosaurus, the dinosaurs of the sauropod suborder (commonly known as sauropods) with huge bodies living on the earth at that time included Diplodocus (26 meters long), Brontosaurus (21 meters long, weighing 25 tons), Supersaurus (42 meters long, shoulders and hips), Mamenxisaurus (22 meters long) and Brachiosaurus (25 meters long, weighing 30 50 tons) and so on.

These giant dinosaurs were plant-eating, with their tall bodies and long necks allowing them to eat the leaves of tall trees. Such a huge body must require a particularly large amount of food, but these dinosaurs all have a relatively small head and a small mouth, how can they meet such a large amount of food? Probably they just had to keep eating.

Scientists speculate that Mamenxisaurus spent 23 hours a day eating! This is probably the best in the world.

Think about how many leaves a Mamenxi dragon eats in 23 hours, and there are thousands of other Mamenxi dragons, and many more giant sauropods. It seems that at that time, the earth must have been densely planted, full of forests, and the natural environment was very superior, so that so many behemoths could live leisurely on the earth.

Now, we don't see such a large animal on land anymore, and the only thing that can compare to them is probably the blue whale that lives in the ocean. Female blue whales can grow to more than 30 meters and can weigh up to 200 tons.

The largest animal in the ancient world was the Argentinosaurus. Argentinosaurus is one of the largest land dinosaurs found so far, and it is a dinosaur found in Argentina. It can reach a length of meters and an overall weight of up to 100 tons.

These dinosaurs were huge, with a single vertebra capable of reaching four feet. They live on the shores of forested lakes, which are abundant in water and food, and many large sauropods live.

Argentinosaurus excavationsFossil Argentinosaurus bones have been excavated with a meter-high dorsal bone, as well as pelvic and hind limb bones, and although the Argentinosaurus is similar to Brachiosaurus, experts believe that it still belongs to the Titanosaurus family. They live on the shores of forested lakes, which are abundant in water and food, and many large sauropods live.
