An alien world totally different from our own, rich in life and full of diversity, said to be more than 50% much richer in species and population than the present earth itself. Filled with vast forests that stretched from corner to corner covering much of the land. A place where Dinosauriformes lizard creatures roamed the earth for over 100 million years. A reign that began in the last years of the Triassic, passing through the Jurassic period and finally ending in the Cretaceous period: they were the longest flavors recorded in the history of the earth. Visual monsters very similar to the Tyrannosaurus Rex, 10-12 meters long, walked and ruled the lands. While their ferocious counterparts, the carnivorous Pterandon, terrorized the skies, an enormous reptile of about 7.8 meters in wingspan, and eventually the seas dominated by the armored Mosasaurus with its large size and speed faster than a modern dolphin, it was a killing machine of clear size and nature. After the Permian nothing seemed to go wrong, the world prospered, no signs of destruction, nothing could have predicted what would happen, but fate declared otherwise and planned its own destiny. What occurred was a swift and swift end to the Mesasoic era. He was gone as if overnight, the event that occurred erased and buried all evidence and life continued as if nothing had happened. Scientists have called this mass murder/apocalypse the KT (Cretaceous and Tetiary) event. The KT Boundary A thin layer of sharp gray clay on the Earth's crust. The boundary from which we get all our information is a geological signature that marked and marked the Mesesoic. It describes and gives us an overview with almost millimeter precision of what happened historically during the fateful days of the event. An increase in carbon levels and a massive change in temperature in some parts of the globe would cause a nuclear winter that would last a few years. These global effects of freezing temperatures lasted for a period of 3 years. Plants begin to dry out and die, this will mean a dramatic decline in the habivore population, which in turn will have a knock-on effect at the bottom of the food chain. This will continuously select survivors because they fail to adapt to the current rescue conditions. Eventually about 75% of the population would die, so dianosaurs and reptiles mate there in their destiny. For many years the earth lay dormant, but a brief burst of life followed as conditions stabilized and evolution took place by probing the earth. These eventually paved the way for motherhood and illuminated our existence.
