The prehistoric devil frog is also called the devil toad. The survival era is about 70 million years ago in the middle and late Cretaceous period, at the beginning of the 21st century, European scientists excavated a pair of centimeter-long frog fossils, scientists estimated that the anal snout was 43-45 cm when alive, stretched and stretched to a total length of more than 1 meter, weighing 9 10 pounds or even heavier. Some scientists have pointed out that this does not mean that the fossil is the largest of the devil toads and that there must be a larger one.
The frog has teeth, and the undulations on its bones suggest that it may have some sort of bony "armor". It is found in the East African continent and Eurasia in the middle and late Cretaceous periods. <>

Phobosa is an extinct species of the order Proboscis pictogram, which lived from the middle Miocene to the early Pleistocene. Male phobias are generally close to 5 m tall at the shoulder and are estimated to weigh more than a ton. The upper jaw has no fangs, and the lower jaw has a pair of fangs that curve greatly downward.
White teeth are characterized by 2 or 3 simple transverse spine (tooth ridges), which are used to cut rods, and the corresponding biting action is common to most other more primitive proboscis orders. Phobos are found in Asia, Africa and Europe. <>

The sarotrocercus is a rat-like creature that usually swims upside down in the sea, and many arthropods on it adopt a similar approach. However, why are your eyes so big, and they are cute again. After being reminded by a friend below, it was found that it is indeed very similar to a bio-open-top bus.

Wiwaxia, first convince yourself that he is an animal, and then convince yourself that he is a annelid. The debate over whether wiwaxia is annelids or mollusks has an interesting answer, and it is no wonder that wiwaxia is a paraclade of a common ancestor group of mollusks and annelids, so it is no wonder that it incorporates different characteristics. <>

The largest shrimp on it, the two-meter-long aegirocassia is the main ship of the Ordovician fleet This prawn makes a foodie move his appetite fingers, but such a big shrimp, I guess the meat is very old. PS: Odd shrimp is not a shrimp, but a taxonomic unique (arthropod?).
Animals, however, in the eyes of foodies, treat it as shrimp. <>

Since the birth of the earth, it has a history of about 4.6 billion years, the earliest life on the earth arose 3.6 billion years ago, and humans evolved about 3 million years ago. So, for the earth, the number of years that humans live on the earth is really minimal.
For billions of years, countless lives have been born on the earth, including the three interfaces of land, sea and air. Some of these beings have a very tenacious ability to survive, and to this day, there are many remnants of antiquity in these lives.
1. Cyanobacteria. It is said that cyanobacteria are the first organisms to appear on the earth, and because of their existence, it is characterized by photosynthesis and living in a large number of colonies, so it is also an important contributor to the supply of oxygen in the world, and it has been since ancient times. It is precisely because of the oxygen-producing properties of cyanobacteria that the foundation for the survival of other organisms on the earth was laid in the future.
That's why cyanobacteria are listed as one of the oldest species in the world.
2. Sponge. Sponges are made up of numerous cells that gather together, so they have no internal organs and no body parts. They live in both oceans and freshwaters, and corals are one of the sponge forms. Sponges are said to have existed since 100 million years ago, and they have evolved ever since, with the largest sponge being about 10 inches wide.
New sponges are discovered every year in the world, and each one can be traced back a billion years.
3. Jellyfish. Jellyfish are the most primitive aquatic species on earth, which began to evolve about 500 million years ago, and they have no brains or nerves, only primitive forms of digestive and sensory organs. Jellyfish are 90% made up of water, have a transparent shape, look like jelly, and have a mouth, from which they eat and discard waste. There are many types of jellyfish, some are edible, some can be used as traditional Chinese medicine, and some are highly poisonous.

What was the Earth like before the dinosaurs? And what are some magical creatures that should not be forgotten by humans? Today we are going to explore that lost ancient era.
Four billion years ago, the earth was very different from now, life was only the simplest bacteria, there were only a few scattered islands floating in the vast ocean, the land was desert as far as the eye could see, and the sky was only dim sunlight. If there's anything more spectacular, it's probably the moon, which was closer to Earth and looked even bigger. The first time that complex life on Earth flourished was in the Precambrian Ediacarat.
About 100 million years ago, in the vast marine cyanobacteria pastures, many vegans lived peacefully with disc-shaped creatures, such as Kimberella and Claude tubeworms. At the same time, there are also some creatures who are not willing to be mediocre and begin to evolve into carnivores, they are like eating a buffet, constantly eating those creatures that are completely defenseless, and finally the buffet is gone, and they themselves starve to death. Only a few surviving species entered a new era, the Cambrian period 100 million years ago.
The era of predators is coming. Echinoderms, vertebrates and arthropods all emerged during this period, gradually occupying various ecological niches in the food chain, and life flourished like never before, which is known as the Cambrian explosion, and at this time the land was still empty, and it was only during the retention season that plants and invertebrates appeared on land. Vertebrates first appeared on land 100 million years ago as Devonian agents, such as a creature called a fish food source, which has the characteristics of both fish and amphibians, and can climb onto land to enjoy warm sunlight.
And in the Carboniferous period 100 million years ago, everything became very interesting, this is a world covered by swamps, the unprecedented prosperity of plants directly led to the unprecedented rise of oxygen content in the atmosphere to an unprecedented 35%, and the animals on land have also been unprecedentedly developed, the most obvious feature is the huge size, the giant road often haunts the dark forest, this guy's body length is close to three meters, densely packed with 750 legs, it looks extremely terrifying, there are giant veined dragonflies with wings about 30 cm long in the air, There are also a large number of insects that are comparable in size to modern birds. Of course, in this era of insect prosperity, it also gave birth to amphibians of extremely large size.

Before the appearance of dinosaurs, there were also animal species that dominated the earth, which were mollusks, trilobites, and echinoderms.

It was a spherical shape, and under the circumstances of the time, the Moon should have been relatively close to the Earth, and there may have been some single-celled organisms at that time.

After research, scientists claim that in fact, as early as the ancient period more distant than the Jurassic period, the color of all life forms on the earth was not as colorful as it is now, in fact, the color of all life forms was purple.

A couple in Dorset, England, inadvertently grow the hottest peppers in the world by growing chili peppers in their fruit and vegetable garden. This pepper is 60 percent hotter than the hottest pepper in the Guinness World Record, and you can't even touch it with your bare hands. Other chili peppers may be so spicy that they will make you cry, but if someone is stupid enough to eat a whole of them, they are guaranteed to be sent to the hospital. >>>More
This is due to the peculiarity of the circle, because the sphere is a central symmetry, and every point on the surface is the same for the center -- the same distance, the same force, and this state is supposed to be the easiest shape to maintain relative to the others. In addition, from the point of view of the formation of the earth, the earth was originally solidified by liquid, and by the action of gravity and tension, it was initially an approximate spherical shape. Moreover, even if the Earth was not circular at the beginning, it would have developed into a sphere during its continuous rotation for billions of years. >>>More
About 250 million years ago, there was an unprecedented mass extinction event on Earth, known as the Permian mass extinction. It was a horrific mass extinction event, with an estimated 96% of all living things on Earth at the time. All the organisms that live on Earth today evolved from the remaining 4% of the species at that time, and the famous trilobites and other creatures of the time also disappeared completely in this event. >>>More
