What is the largest animal that has appeared on Earth in the 4.6 billion years of history?

When it comes to the largest animals that have ever lived on land, everyone knows that they are dinosaurs, so which dinosaur is the biggest? Let's take a look at the picture below, we know that the huge dinosaurs are all on it, and you can also feel what humans, elephants, and even whales will look like in front of dinosaurs.

We often say how the ancient dinosaurs were, but in fact, the dinosaur was not an animal, but there are many, many types, and the species may be richer than today's mammals, such as the pterosaurs flying in the sky There are many species, and there are many types of ichthyosaurs swimming in the water, as for the dinosaurs that live on land, there are even more.

So which dinosaur was the biggest? In fact, the current bioarchaeological community is also unclear, because many giant dinosaurs have not excavated complete skeletons, some only found skulls or thigh bones, etc., so it is difficult to judge how big they are, such as tidal dragons, biologists only found its meter-long humerus (upper arm bone), inferred that its size is very large, but there are no complete skeleton fossils, so it is impossible to estimate its weight more accurately.

In addition, there is the Argentinosaurus, which belongs to the titanosaur class of sauropod dinosaurs, a vertebrae are more than a meter high, more than a meter long and wide, and weigh more than a ton, and it is inferred that this dinosaur is 30 to 40 meters long, about 12 meters high, and weighs nearly 100 tons.

There is also a dinosaur called the fragile dinosaur, the height of a vertebra or up to a meter, the estimated length of its thigh bone is 4 meters, the body length is close to 60 meters, the height can reach more than 15 meters, and its weight is estimated to be between 120 and 220, and the overall weight can exceed that of today's whales.

However, at present, people generally believe that Zhensaurus is the largest dinosaur, because the fossil skeleton unearthed is relatively complete, the body size of this dinosaur is very long, usually about 30 meters, and even some are as long as 50 meters, two Zhensaurus can run through a 100-meter runway, it is also the longest dinosaur that has been found, but its height is also very high, usually more than 10 meters, individual shoulder height is more than 12 meters, weight between 30 and 80 tons, some people think that it or more than 100 tons, It can reach the weight of 20 elephants, such a huge weight, so that the earth trembles when it walks, just like **, so it is named Zhenlong or **dragon.

However, the weight of the earthquake dragon is also based on estimates, the shock dragon belongs to a kind of diplodocus, some diplodocus is even less than ten tons, and ** dragon is a huge body of Diplodocus, although the unearthed fossils are relatively rich, but the weight is not easy to estimate accurately, some bioarchaeologists believe that the largest dinosaur with accurate weight is the Shi's dreadnought, which has "the largest reliable calculated weight among land animals", one of the dinosaurs that has been found weighs tons, equivalent to a heavy tank full of ammunition.

The largest animals ever appeared on Earth, of course, were dinosaurs, but they are extinct.

Dinosaur. Because the size of dinosaurs was extremely large, the largest could reach tens of meters long, so the largest animals that appeared were dinosaurs.

The blue whale is the largest creature on Earth, much larger than the dinosaurs that lived in prehistory, weighing between 15 and 20 tons and measuring 24 to 34 meters in length.

Giant Dragon. Because the giant dragon was more than 40 meters long and weighed more than the blue whale, the largest animal in the history of life on Earth was the giant dragon.

The largest animal is the blue whale, which is particularly large, weighing more than 180 tons and reaching a length of 33 meters, a particularly large reminder and the largest animal on the planet at the moment.

Summary. The tissues of our plant bodies gradually became more complex, and we entered the age of ferns, the gastrulation cavity, that is, the digestive circulatory cavity, forming a dense forest, and their mouths occurred at the opposite end of the original mouth, or the angiosperm age, molluscs, until now, so arthropods are believed to have evolved from ancient annelids.

There are about 5 million to 100 million species of organisms on the earth, and these creatures evolved gradually.

For the evolution of plants and animals.

This still forms a complete scientific system.

From a human perspective, looking at things before or after eons of age always feels a little ridiculous. But in fact, human geology and paleontology are all committed to studying the past history for a better future. With humanity's current grasp of what is happening in Earth's geological time, we seem to be qualified for the Earth's biosphere 100 million years from now.

Key hand chop. Of course, the earth in 100 million years will actually have a close relationship with human beings. Because of human industrial activities, the greenhouse gas content on the earth is increasing at an unimaginable rate, which is actually a process of quantitative change causing qualitative change. Although it is considered by human beings to be short-sighted that greenhouse gas emissions only increase the earth's temperature by one or two degrees Celsius, if quantitative changes continue to accumulate, there will be a day when qualitative changes occur.

The temperature of the Earth during the Carboniferous Period, which was about 15 degrees Celsius warmer than the current average, was a real greenhouse Earth, which produced the most lush flowers, as well as the most bizarre animals. In 100 million years, the earth may return to the Carboniferous period. The same goes for animals.

Let's take a look at what the Earth will look like in 100 million years. As the tectonic plates continue to move, Antarctica drifts to the south temperate zone, while Australia, Asia and North America merge again to form a new primordial continent.

Rising sea levels have also turned many low-lying landmasses into floods. In Bangladesh in South Asia, this low-lying area has the potential to form a vast coastal swamp tidal flat, a rich but shady body of water that is capable of evolving terrifying species. The consequences of rising sea levels of nearly 100 metres have been enormous, with shallow seas replacing offshore plains as an important ecosystem.

Compared to the deep sea environment, shallow waters are a paradise for biological evolution, with plenty of sunshine and nutrients. Many new species will also emerge that live exclusively in this ecosystem.

For example, shallow sea octopuses may appear. This is a new member of the octopus family, which is already a species that can adapt to the offshore environment, and in the face of such a vast shallow sea, the octopus will naturally not be absent. In shallow waters, octopuses are at home to their wrists and feet, and it is likely that they have evolved the ability to breathe air, adapting to the varying depths of shallow waters.

Then there are the giant gliding birds. It is believed to have evolved from falcons, because of the movement of the plates, which created higher plateaus, and this giant bird resembles the pterosaurs of the dinosaur era, from the plateau with its gliding ability to dominate the sky. What do you think?

The largest animal on Earth is the blue whale, which is larger than the largest dinosaur, but it is still not the largest creature on Earth. For example, the tallest tree is over 115 meters, which is taller than the Statue of Liberty, and there are many creatures that we can't see, and they may be much bigger than we think.

The blue whale is by far the largest and heaviest creature on earth, and it is surprisingly large even when it is born, and the blue whale eats a lot of food, so it grows very fast.

I think it's a blue whale, Nanjing is very large, and they weigh 9 tons, so I think it's very scary, I think it's a blue whale.

I think the biggest creature is the blue whale. It is the largest known and still alive. After hundreds of millions of years of transformation, we still live in this era.

I think from ancient times to the present, the largest living thing on earth today should be plants. Because in terms of the longevity of the plant and the size of the plant, it should be the first.

I thought it was a dinosaur. Dinosaurs, as the masters and rulers of the last century, are the largest creatures in the world from ancient times to the present day.
