What animals have survived from the time of the dinosaurs to the present?

Not all prehistoric animals are extinct! 5 species of animals have lived from prehistory to the present.

I think it was possible for humans to exist in the age of dinosaurs. But since no relevant information has been found to indicate that this is true.

In the age of dinosaurs, there were no human beings, and don't believe these statements on the Internet, because these statements are very unreliable.

No, humans didn't exist in that primitive era, when there were only some sea creatures, dinosaurs, and birds.

There are many creatures that have survived from the age of dinosaurs to the present, such as many birds, which are a branch of dinosaurs. There are also the lizards, crocodiles, snakes that we are familiar with, and these cold-blooded animals have also survived from that time to the present. There are also some insects, such as cockroaches, bees, lice.

There are also some in the water, such as lobsters, turtles. Some mammals, such as platypus, and so on.

The age of dinosaurs is a big era that dominates the earth, the Cretaceous is a heyday, of course, it is said that it is the heyday also means that it is about to decline, and I don't know whether it is a natural disaster or a "man" disaster, some people say that it is an asteroid that collides with the earth, and some people say that it is a ghost made by aliens, which cannot be verified. But the mainstream thought is that an asteroid collided with the Earth 65 million years ago, causing a sharp change in the Earth's climate.

Because of the drastic changes in the climate at that time, the temperature dropped severely, and the earth entered an ice age, and a large number of organisms did not have enough food, and only some good creatures were fortunate to survive. Although it was a fatal impact, some of them were lucky enough to survive, including some aquatic creatures and some small creatures.

For example, the well-known cockroach, which can be said to be a very annoying creature in our house, but it has existed longer than we humans. Think of him as having experienced the mass extinction of the dinosaurs. Because the fatal disaster did not have a great impact on this guy, because his vitality is extremely tenacious, a cockroach, if there is no head, it will not die at first, and the reason why he died is because there is no part to eat.

There are also lice, bees, and they all survive to this day.

There are also some avian creatures, such as chickens and birds, their bones are very similar to the dinosaurs at that time, and many people now say that the most dinosaur-like ones now are not only chickens? There is also the lizard, he looks like a dinosaur, but he is not related, many of the larger lizards have died, but the ones that survived at that time were all smaller, and now they are all over the world.

The mammals of the age of dinosaurs were: platypus, thorny anteater, echidna.

Reptiles from the age of dinosaurs: snakes, lizards, crocodiles. Among them, crocodiles have been on Earth for about 100 million years. There are 23 species of crocodiles living today, including alligators, American crocodiles, and caimans, to name a few. Crocodiles in the Mesozoic era were generally larger than their current counterparts.

Amphibians in the age of dinosaurs: frogs, toads, axolotls, earthworms.

Dinosaurs contemporaneous sea bucket stupid marine animals can be roughly divided into the following three categories:

Foraminifera, which are shelled single-celled organisms.

Echinoderms, including starfish, sea urchins, sea cucumbers.

A soft, shelled mollusk.

Clams, snails, lobsters, crabs, and shrimp also survived the K-T event, eventually becoming the food of marine predators and the food of humans. Before the first terrestrial dinosaurs ran on the ground, sharks lived in the ocean for a long time. To this day, they are the most famous carnivores in the ocean.

Today's eight-eyed eels and lampreys are very similar to the extinct armor fish and acorns. However, the most famous of marine life dating back to the Mesozoic era are coelacanths, which are the only survivors of aquatic flesh-finned animals. Flesh-finned fish are leaf-finned, bony fish.

Of course, there are still many flesh-finned animals in the world, but they diverged long before the Mesozoic Era and became the ancestors of quadruped vertebrates.

x04 x03At the end of the Paleozoic Era, the formation of the combined paleocontinent expanded the global land area and distributed continental sediments extensively. In the middle and late Mesozoic Era, the joint paleocontinent gradually disintegrated and the new ocean was formed, and by the end of the Mesozoic, independent land masses such as Eurasia, North America, South America, Africa, Australia, Antarctica and India were formed. It is separated by the Pacific, Atlantic, Indian and Arctic seas.

Birds and mammals appeared during the Mesozoic era. During the Mesozoic Era, there were some mammals, some of which were the ancestors of later monkeys, that is, the ancestors of humans today. Marine invertebrates are characterized by the flourishing of ammonites, so it is also called the ammonite age.

Freshwater invertebrates, with the continuous expansion of land, the favorable conditions of rivers and lakes, the development of bivalves, gastropods, lobes, mesozoans, etc., are very important for the division and comparison of terrestrial strata. x04 x03 Birds and mammals appeared during the Mesozoic Era.

By the end of the Mesozoic Era, angiosperms replaced gymnosperms and became important.

At the end of the Mesozoic Era, there was a famous extinction event, especially the extinction of dinosaurs and ammonites. It has been suggested that extinction events are related to the impact of small extraterrestrial bodies on the Earth, but the exact cause needs to be determined by further research.

1. True ferns and gymnosperms are very abundant in plants. In the late Mesozoic era, a very significant event occurred, that is, angiosperms achieved great development, and gymnosperms still occupy an important position. Angiosperms are currently the highest plant species in the plant kingdom.

At the end of the Mesozoic Era, there were famous extinction events, especially the extinction of dinosaurs, ammonites, and non-avian dinosaurs.

2. Dinosaurs belong to reptiles, and the era of dinosaurs is often said to be the era of reptiles, before which there were amphibians and coelenterates, and coelenterates were the first to flourish, and then there was a flourishing period of amphibians, and then a flourishing period of reptiles.

3. Most of the mammals at that time were very small nocturnal insectivores. Wu's mega-cranial beast, which is the earliest known mammal, it lived in the age of dinosaurs, and may still be oviparous, similar to today's platypus and echidna, the mega-cranial beast is not as big as a human hand from head to tail, and can only survive in the crevices of reptiles.
