The plates move again, below is a new continent, Gondwana, with a warm temperature of 30 degrees. These lands should be covered with plants and reploial creatures, but there is not much.

There is only one explanation, the sun, whose radiation swells the surface, when oxygen meets the radiation of the sun, another type of gas called ozone forms, this gas forms a layer around the whole planet, it thickens and prevents the passage of radiation , this forms the moss.

There are no complex life forms, the Earth's crust is divided into several layers, the core heat generates movement and the plates move.

The plates keep moving away, there are new continents, the Atlantic Ocean is born and in the middle a volcano.

The entire seabed has split in two and along it has sprung a mountain range of mountains and volcanoes, the water here is hot as the lava comes out of the interior of the earth, as it cools creates a new mountain range and a new ocean bed that's what breaks Pangea, produces the separation of platforms and reconfigures our world

The world of dinosaurs is now different, but these animals are as dominant as before but now seem invincible.

Small mammals that have evolved, since the mass extinction of 185 million years ago, are prey to dinosaurs, live under land and only go out at nigh

A herd of creatures emerge in the Siberian meadows, evolution has taken a giant step the small lizards of before are now giant reptiles.

They are called Scutosaurs (herbivorous reptile) and there are also predators, the Gorgonoxides, a perfectly designed prehistoric killer machine.

Meteor shower, it is the remnants of the formation of the solar system that collide with the earth, these meteorites contain lime and water, for more than 20 years the meteorites continue to fall allowing the formation of water on the earth.

The core is still liquid, the outside has already cooled the earth is no longer a liquid ball of lava.

The moon's proximity affects the earth's gravity causing huge tides and tornadoes

200 million years ago, there is only one supercontinent called Pangea, which stretches from pole to pole. After the trauma of mass extinction the planet is healing, temperatures are stabilizing, acid rain is being neutralized and vegetation is returning, with 95% of all life the missing land is ready for the emergence of a new species; Dinosaurs.

The Earth's crust begins to thin and expels lava and trembles with earthquakes as if it were being tensed by the earth's internal forces, the Earth's plates move, Pangea breaks and a new ocean is created.

Ocean currents push nutrients into coastal waters which attract millions of fish, with so much life comes death the dead fish and plankton cover the seabed for the next 10 million years layers of rock will bury and heat the dead creatures, dead fish and plankton turn to oil.

Ice melts, hydrogen peroxide breaks down and produces large amounts of oxygen.

The earth is waking up and it's a very different place. At that time 600 million years ago, the atmosphere is warmer, as in the summer, on hard days 22 hours, if you add all the amount of water from the earth is the perfect recipe for life.

Violent meteor shower releases carbon and primitive proteins reach the bottom of the ocean,The temperature of the same was 0oC.

An underwater city is formed, microscopic life is formed; single-celled bacteria.

This end gives opportunities for other species to emerge, mammals as they lived under the earth have been saved from fire and heat and by eating everything they can thrive, they evolve normally.

The atmosphere was very similar to that of our time, the temperature is 24oC and the days last a little less than 24 hours.

The earth's plates begin to move again with their continents. Indian and Asian platforms collide, and both begin to rise, which was once an ocean floor rises across a 2500 km line, a huge mountain range rising: Mount Everest, from the melted water of its peaks form large rivers , which would then provide water to nearly half the world.

There was only the sun surrounded by dust, the earth did not exist,little by little gravity turns the dust into small rocks, they collided with each other for many millions of years, constituting larger bodies, until they gave rise to the earth.

20 million years ago there is an asimius that could be seated all day but as the world is changing. The mountains that are forming act as a wall that does not allow moisture to enter the ocean indicating what produces more heat, forcing the apes to enter the habitat in search of food. They stopped rubbing their knuckles and stood walking on two feet. It is the most important step for humanity.

1.5 million years ago, a homo erectus man and child left their first footprints in Africa. Human history begins here.

700 Million years after the birth of the planet, it is full of water.

Islands emerge, volcanoes erupt and this causes the formation of a volcanic island, lava cools and millions of years later the primary continents form.

The first continent is formed "Rodinia". The supercontinent splits in two, the intense activity geology forms volcanoes that release carbon dioxide, it is mixed with water, acid rain occurs, the dioxide stays in the rocks.

Temperature 50o Sub zero; the first ice age occurs, extending from the poles; blocks 3 km high. The earth is a huge snowball.

540 million years ago, in an oxygen-filled ocean, primitive bacteria have evolved, a handful of them must have resisted the great frost

Here the wiwaxias (extinct genus of molluscs)

In the deep ocean rocks formed, grow from the seabed stromatolites (pyramids of bacteria) which make the first photosynthesis processes. From this natural process oxygen is produced, the oxide is mixed with iron and ferrous plates are formed.

Gaseous materials escaped from the earth's interior to form the atmosphere.

The temperature amounts to 2200oC, There is no air, there is only carbon dioxide, nitrogen and hot steam.

The earth is a boiling ball of liquid rock (Lava), a rock the size of mars colliding with the earth, this causes an expansive wave; with this explosion formed the moon of the earth, it was 22,000 km from the earth (closer than normal).

A massive amount of lava rises from inside the earth, the lush paradise is now an inert hell, the Scutosaurs and Gorgonoxides are dead, they are the first victims in the greatest mass extinction the world has ever witnessed, extinction permiana

At the other side of the continent it is as if nothing had happened, only ash from eruptions 16 thousand kilometers away, incandescent ash suffocates and kills animals all over the world, the atmosphere is filled with sulfur dioxide from the eruptions , when it rains the gas is transformed into sulfuric acid and burns everything on what falls, at first it seemed like it was a local disaster, but it is a global disaster.

The atmosphere is overheated, the gua evaporates and the vegetation perishes disappearing all the life on the continent and the oceans become pink, everything has disappeared except the algae.

In the water arises a strange fish called Tiktaalik, its neck allows it to enter the ground and uses its fins as if they were legs to get out of the water.

Water; where plant life is at its peak, for more than 15 million years, these creatures called tetrápods (branch of vertebrate animals with four limbs) evolve, their limbs strengthen and go more and more time out of the water, until it does 360 million years make soil home, all quadrupedal vertebrates will evolve.

A large fragment of rock is approaching, 10 km in diameter and travels more than 70 thousand km/h directly to earth. He's heading for the Gulf of Mexico. By impacting the earth in a split second, the world will change forever. At the time of impact the asteroid had a height of almost 11 thousand meters, as so much the force with which it hits destroys everything it touches, even the asteroid itself is shattered at the time.

Minutes later thousands of miles from where the asteroid fell, the earth is subjected to an attack from all parts of rocks, asteroid wrecks and tsunamis that destroy everything in its path.

Dust and lava spread and envelop the entire planet, the sky is full of smoke and ash and acts like a solar lamp. The surface of the earth is heated to 275oC and vegetation begins to burn immediately. After months of impact even smoke and ash block the sun's rays, this means that there is not much sunlight and the rest of vegetation dies, the animals that fed on it also starved. 65 million years ago the impact has burned and blown up the dinosaurs after 165 million years come to an end.

Animals conquer the continent.!

EXTINTION OF DINOSAURIOS

The Cretaceous-Tertiary mass extinction was a period of mass extinctions of species approximately 65 million years ago. It corresponds to the end of the Cretaceous period and the beginning of the Tertiary period. It is also known as the mass extinction of the K/T boundary (from the German Kreide/Terti-r Grenze), to point to the border between the Cretaceous-Tertiary. The exact duration of this event is not known. About 50% of the biological genera disappeared, including most dinosaurs. Many explanations have been proposed for this phenomenon; the most accepted was that it was the result of an asteroid's impact on Earth from space..

APPEARANCE OF THE MAMMALS

Today's mammals descend from primitive synapsids, a group of amnite teprepods that began to bloom in the early Permian, some 280 million years ago, and continued to dominate over terrestrial "reptiles" until about 245 million years ago ( Triassic), when the first dinosaurs began to emerge. Due to their competitive superiority, the latter made most synapsids disappear. However, some survived and became the first true mammals towards the end of the Triassic, about 200 million years ago. The oldest known mammals are, on the one hand, multituberculates and on the other the australosphenid, groups dating from the Middle Jurassic

This is one of the most dynamic periods in Earth's history, the Cambrian explosion, the increasing oxygen levels that allow creatures to grow and develop bone skeletons, there are worms, sponges and trilomites (distant relatives of insects, lobsters and scorpions)

Life in the oceans flourishes, from microscopic bacteria to "monsters" like anomalocaris.

In this period it was where an animal appeared that is called Pikaia, which mice 5 cm long but possess what could be the first spine

Hylonomus (relative animal of the lizard) was one of the first animals to leave their eggs out of the water, as their eggs contain all the water and nutrients that the young need. The egg is one of the main evolutionary advances, now animals can leave the water and conquer the continent
