History of Animals And his Beginning

 History of Animals

At the beginning of  Animals:- Scientists believe that about 55 million years ago, there was such a change in the sea, due to which there was a lot of development in the organisms, which we call the biological big bank, about 50 million years ago, the first prickly fish was born, from which the bones of the spine were born in them. Scientists believe that about 400 million years ago, our ancestors set foot on the earth from the sea, which we call amphibians, then after that, a reptile was born.

Dinosaurs became extinct six and a half million years ago:- 

Scientists believe that about 25-30 years ago, dinosaurs came to the earth, which ruled the earth for 15 to 16 crore years.

Dinosaurs and all their related species were extinct from the world about 65 million years ago. At that time a large meteorite fell on Mexico near America. Due to this effect, all species of dinosaurs became extinct from the earth.

Human and dinosaur encounter:- In the time of dinosaurs there were no humans and now they are completely extinct. Something seems to happen between humans and dinosaurs only in movies or stories. But it is also true that predatory dinosaurs were very dangerous even in that era. Now researchers have found the area in Africa where there was a lot of such animals.

Dangerous animals roam the earth:- 100 million years ago the earth was not a place for humans to live in. In those days, giant reptiles used to crawl on the earth, but some areas were especially very dangerous where predators like flying snakes and crocodiles roamed in them.

What is an area of Research:- In research conducted at Portsmouth University, a team of palaeontologists studied fossils in the Sahara desert of Africa. This area is called Chemchem Group. This is an area with Cretaceous rocks in southeast Morocco.

How animals were found:- It was told in the research that this area used to be a very large river area then. It was full of aquatic and terrestrial creatures. These included some giant predatory dinosaurs, including Carcarodontosaurus, with 8-inch-long sharp teeth, and Deltadromes of the 8-meter-long raptor family. Apart from this, there were also predators like flying reptiles i.e. Pterosaurs crocodiles.

large river area:- The place was then filled with many fish, including large coelacanths and lungfish. The coelacanth then used to be four or five times larger than today's coelacanth. Apart from these, there were also sharp-toothed sharks like Danger Onchopristis.

Africa's rich biological history:- Researchers believe that this study is the largest research of such fossils in the region in the last hundred years so far. This research will shed a lot of light on the past life of Africa. Africa has always been a region of great biodiversity. At this time there are deserts, dense forests, high grasslands, all kinds of climates can be seen. But the history of this region has also been no less rich.

At The chemical element Atmosphere:-
When eubacterium evolved a minimum of two.4 billion years agone, they set the stage for a noteworthy transformation. They became Earth’s initial photo-synthesizers, creating food mistreatment water and therefore the Sun’s energy, and cathartic chemical element as a result. This catalyzed an explosive, dramatic rise in chemical elements, creating the setting less hospitable for different microbes that might not tolerate chemical elements.
