There were many prehistoric behemoths that may have gone extinct much later than is now estimated.
Dinosaurs, for example, underwent mass extinctions in the late Cretaceous period, 45 million years ago. But there is no evidence that none of them were there at that time. It is very likely that the species of dinosaurs lived on Earth for tens of millions of years. It's just that there are fewer than in the most prosperous period. Fossils can only be formed by chance. The bones of most animals will eventually be completely reduced to dust and return to heaven and earth.
There is no more advanced structure for living things, and as long as there is an environment suitable for them, they can survive and reproduce.
The largest known animal species on Earth is still alive today. They are the blue whales of mammals that live in the ocean.
Blue whales can reach 33 meters in length and weigh up to 181 tons.
The ocean is suitable for this huge creature to survive.
Today, the heaviest animal on land is the elephant, which can weigh about seven or eight tons. In the era of dinosaurs, there are too many dinosaurs that easily weigh more than ten tons, and there are many types of dinosaurs that can exceed 100 tons.
The largest land mammal found today is the ancient giant rhinoceros that lived between 34 million and 23 million years ago. Its body is more than 8 meters long, up to 12 meters from nose to tail, shoulder height is more than 5 meters, the height of the neck can reach 9 meters, and the adult weight can reach 20 tons.
The presence of ancient giant rhinos suggests that there were dinosaur-class land creatures in the tens of millions of years after the dinosaur era.
There was an Argentine giant eagle 6 million years ago. It weighs 70 kg and has a wingspan of more than 7 meters. It was simply a small plane.
At the end of the last ice age 10,000 years ago, a large number of giant species disappeared.
These include mammoths and saber-toothed tigers.
The emergence and existence of life is actually an accident.
