65 million years ago, due to a particularly big disaster on the earth, resulting in the extinction of the dinosaurs, and 450 years ago, human beings were born, but there are still many ancient creatures on the earth today, survived, it is incredible that other creatures of their time have long been extinct, but these creatures have been able to adapt to the changes in the earth's environment and live until now.
Among them, the first is the giant panda, now the giant panda has become a national treasure of China, but he has survived on the earth for nearly 8 million years, also known as "living fossils", as early as ancient times there are many records about the giant panda, and in these records the giant panda has a lot of names, such as iron beasts, flower bears and tapirs, etc., in myths and legends, the giant panda is the mount of Chiyou in the Jiuli tribe in ancient times, when the Yellow Emperor defeated Chiyou, The giant panda has become the landline of the Yellow Emperor, and the character of the giant panda is also very likable, and now the giant panda has become China's most precious national treasure.
The second is the platypus, in fact, the platypus was born on the earth 25 million years ago, when they lived in what is now Australia, as the most primitive mammal, it is also a lowly mammal, until now the platypus has not fully evolved successfully, and the platypus is not born, but an oviparous animal.
In 2013, a scientist from Australia found a fossil of the ancestor of the platypus, the shape of this fossil is very similar to the current platypus, but it is twice as large as the current platypus, so to speak, the platypus has a very important scientific significance, they have experienced nearly tens of millions of years, until now it is not extinct, this is also a very amazing creature.
The third is the koala, the koala is also known as the koala, he is also Australia's national treasure, and experts have also excavated the fossils of the koala's ancestors, 25 million years ago from today, the ancestors of the koala appeared on the Australian continent, and the four ancient creatures that are still there, 1 in China, the fourth dinosaur has not lived it! At that time, koalas were not like now, they were social animals, living in tropical rainforests, I didn't expect that koalas had a history of tens of millions of years.
The fourth is the crocodile, the crocodile is also one of the most primitive animals today, he lived in the Triassic period more than 200 million years ago from today, and now the crocodile has many characteristics of dinosaurs and reptiles, which has a very special significance for scientists to study some ancient creatures, from 65 million years ago dinosaurs ruled the earth until now, the crocodile has hardly changed at all, experts believe that the reason why the crocodile has survived for so many years, It is likely to have something to do with their predatory habits, because crocodiles move very slowly, so it is difficult to catch those animals that are very fast, resulting in little movement and very slow physical exertion. Do you know any ancient creatures that are still alive tens of millions of years ago?

US scientists have recently discovered the world's oldest microorganism, which has existed for 250 million years, breaking the current record for the oldest organism on Earth and providing the latest justification for the theory that life on Earth may have originated in outer space.
The bacteria, called 2-9-3, is naturally sealed in a salt crystal and is found in a nuclear waste landfill 2,000 feet underground in the desert of New Mexico, USA. Scientists at the University of West Chester in the United States took the bacteria out of the salt crystals in a sterilized environment, and then used a co-catalyst extracted from Anji acid to revive the bacteria that had entered a state of suspended animation.
The researchers first disinfected the surface of the salt crystal, killing the modern bacteria attached to it, and then carefully removed the bacteria from the crystal in a sterilized environment. The researcher explained that this was done to ensure that the bacteria in the crystals did not sneak in by accident during the experimental analysis.
The researchers claim that since the crystal showed no signs of damage, and because it came from a salt crystal that formed 250 million years ago, they believe that the bacteria sealed inside are the same age as the salt crystal, i.e. about 250 million years old. They claim that according to their rigorous disinfection procedures, the bacteria inside the crystal are accidentally contaminated with a chance of only one in a billion. Prior to this, the oldest microorganism on Earth, found on bees preserved in amber, was estimated to be about 25 million to 40 million years old.
