The past of the earth is known with dinosaurs; But you should know that before the dinosaurs, there were strange monsters on the earth that could scare you. Although they experienced the worst end in the eire history of the planet.
Dinosaurs ruled the earth for 170 million years. They were gigaic and amazing animals and even today they surprise people with their fossils. Although you should know that the earth was full of differe animals before the dinosaurs and has a very ieresting history. During that period, very iense eves occurred and the face of the planet changed forever. For a more detailed examination, we must travel to 300 million years ago, the Permian period.
The Earth has had a fascinating and strange history before the dinosaurs
If you could travel back to the Permian period, you would definitely not know the Earth. At that time, all the coines had joined together and formed the supercoine Pangea. A world ocean also surrounded this coine. About 300 million years ago, the amou of oxygen on the planet was lower; But man could still breathe. Also, the average air temperature reaches 4 degrees Celsius. After 10 million years, the ice age gradually ended and the global temperature became warmer. This also provided the conditions for the greening of the supercoine Pangea.
In 290 million years ago, the earth belonged to volcanoes and there were no dinosaurs. Volcanic eruptions were so iense that they changed the face of the earth. Conditions were set for evolution, and trees with new conditions were seen all over Pangea. At this stage, various insects appeared on the planet; But the most importa of them were cockroaches. Cockroaches on Earth before dinosaurs were about the same size as today’s crows; But fortunately, they could not take the throne. This title belongs to the ancestor of early mammals, Dimetrodon.
Encouering Dimetrodone was not a pleasa experience. This animal was 5 meters long and its weight reached 225 kg. There was also a strange sail on Dimetrodon’s body, whose exact function is not known. Some think that it is used to regulate the animal’s temperature, and some consider it a defense mechanism to scare others. Dimetrodon was the apex predator of the food pyramid and could tear the body of any animal io pieces with its sharp teeth. On the earth before the dinosaurs, no one dared to approach Dimetrodon.
About 273 million years ago, it was the turn of the Trapsids to rule the planet. They had strong jaws with large teeth. A 5 meter beast that was seen in differe species in Pangea. During this period the Earth coinued to warm. The average temperature of the earth reached 25 degrees Celsius and volcanoes regularly released greenhouse gases io the atmosphere. Life also flowed strongly in the ocean. Bony fish and early sharks lived in the waters. Although it was not Megalodon’s turn yet.
It was almost 260 million years ago that another animal was added to the planet. Lystrosaurus was differe from the terrible monsters of that time and was a herbivore. Lystrosaurus can be seen as a combination between pig and reptile. Synodes were also prese in this period. They were considered very early, one-meter versions of today’s rats. Everything indicated that the earth is going to be filled with differe animals; But something dangerous was happening.

Many volcanic activities had caused a huge amou of gas to eer the atmosphere. As a result, the amou of oxygen in the air had reached only 10%. For comparison, it should be said that currely the air has 21% oxygen. Also, the volcanic fumes caused the temperature of the earth to rise regularly. The work reached a poi where the average temperature crossed the border of 28 degrees Celsius and disaster occurred. About 252 million years ago, the Permian period ended. At that time, 90% of all animals and plas on the planet were destroyed.
This strange eve is called the Great Extinction and it is considered the deadliest mass extinction eve in the history of the earth. Scieists still disagree about the main reason for such a catastrophe; But most people believe that the volcanic ash blocked the sunlight and caused the plas to die. The death of plas also disrupted the food chain and led to the death of animals. Also, the temperature increased regularly and the ocean lost a large part of its oxygen. As a result of this great disaster, 95% of all sea creatures of the Permian period became extinct. Therefore, it can be said that the planet before the dinosaurs was not an attractive option for living.
