All the history involving the universe planet, always with a sense of mystery and vicissitudes, always shocking people, is it really like the world plate said on TV, long time will be divided, long time will be together? The Earth's continental plates, which were a whole 600 million years ago, are now what they are today. First, let's start with a dynamic diagram.
The Ediacaran period 600 million years ago on earth in the southern hemisphere
About 750 million years ago, the continent of Rodinia split into the former continents of Lauia, Congoklaton, and formerly Gondwana (Gondwana excluded the Congolese Shield and Antarctica). The continent of Lauya further split and moved toward the South Pole. The original continent of Gondwana reversed counterclockwise. 600 million years ago, Congo Craton was located between the continents of the former Lauia continent and the former gondwana continent, which converged to form the continent of Panocia.
Cambrian (543–490 million years ago)
540 million years ago, or 60 million years after the formation of the continent of Pannosia, the continent of Pannosia split into four continents: Lauren, Baltic, Siberian, and Gondwana. The pan-ocean expanded with the division of the pannosian continent. The Cambrian climate was warm, sea levels were rising, and shallow seas flooded large areas of lowland. This shallow sea zone creates extremely favourable conditions for the birth of new species.
Ordovician (490-438 million years ago)
At the end of the Ordovician, 440 million years ago, it was the third largest extinction event in Earth's history, with about 85% of species perishing. Paleontologists believe that this extinction was caused by a cooling global climate. About 440 million years ago, the land on which the present Sahara is located was once located at the South Pole, and when land converged near the pole, it was easy to cause thick ice accumulation--- which was the case in the Ordovician. Large glaciers cool ocean currents and atmospheric circulation, the temperature of the entire earth drops, glaciers lock water, sea levels are lowered, and the rich coastal biosphere is destroyed, resulting in the extinction of 85% of species.
Shilugi (438–410 million years ago)
At the beginning of the Silurian period, the Antarctic ice sheet rapidly melted, resulting in the weakening of the Silurian ocean and atmospheric circulation, the diagonal climate zone was not obvious, the deep sea part was relatively warm, the oxygen content was low, and it was easy to become a stagnant current. As a result, with the exception of the high-latitude gondwana continent, most of the other plates are in hot and dry or warm climates.
Devonian (41–354 million years ago)
During the Devonian period, many areas arose, exposing the sea to become land, and the paleogeographic appearance changed greatly compared with the Early Paleozoic Era.
During the Devonian period, seawater covered about 85% of the Earth, and its distribution was characterized by the vast Paleo-Pacific Ocean that made up the Northern Hemisphere, the Paleo-Mediterranean Sea north of gondwana paleoclast and the narrow intercontinental sea between the various land masses, and the surface sea above the continent.
The second mass extinction occurred in the late Devonian period, also due to the cooling of the Earth's climate and the retreat of the oceans.
In the late Devonian Period, about 36,500 years ago, after two peaks with an interval of 1 million years, it was the fourth largest species extinction event in Earth's history, and marine life was severely damaged.
Carboniferous (354–295 million years ago)
The oldest fossil bones that can be counted as reptiles were found at the end of the Upper Carboniferous period. At this time, the earliest eggs with hard shells also appeared. The earliest wingless insects appeared in the Lower Devonian era, and by the Upper Carboniferous there were already winged insects. These insects are not yet able to fold their wings (such as dragonflies, etc.), and more than 500 species of insects have been found in the Carboniferous coal formations.
The main fish in the Carboniferous Sea were the handy radiated fish. Sea lilies are new creatures that emerged in the Carboniferous Period, and they belong to the echinoderms. Other animals that have left many fossils are the moss phylum and the shivag and spindle, the latter two being single-celled animals, but they can reach up to 10 cm in size. The only vertebrates that lived on land during the Carboniferous period were amphibians, but they also retained considerable aquatic habits. Since they have no competitors on land, they are very diverse, some growing up to 6 meters long.
Permian (295-250 million years ago)
Temperatures in the Early Permian were considered fairly low, only to gradually change after that. Huge deserts cover the western half of Pangea, and extensive coal-bearing construction in the southern hemisphere marks a temperate and humid climate.
The end of the Permian produced the worst mass extinction event ever recorded, with an estimated 96% extinction of species on Earth, of which 95% of marine life and 75% of terrestrial vertebrates went extinct. Trilobites, sea scorpions, and important coral taxa all disappeared. Terrestrial monobow taxa and many reptile groups also went extinct. The mass extinction caused the major creatures that occupied the ocean for nearly 300 million years to decay and disappear, giving way to new species, and the ecosystem received a most thorough update, paving the way for the evolution of reptiles such as dinosaurs.
Triassic (250-205 million years ago)
The formation of Pangea began in the Devonian Period, through the continuous collision between continents and continents, until the late Triassic period, which led to the formation of this supercontinent. The Triassic period ended with an extinction event, especially for marine life: the extinction of tooth-shaped stones, the disappearance of all marine reptiles except ichthyosaurs. Invertebrates such as brachiopods, gastropods and shells have been hit hard. In the ocean, about half of the species of 22% of the genus disappear.
This extinction event was not the same everywhere. In some places there is almost no impact. In some other places virtually all the dragons and most of the arches have disappeared. Many of the early dinosaurs also went extinct, while those that were more developed survived. Many slottates were also extinct. Surviving plants include conifers and cycads.
Jurassic (205–137 million years ago)
The atmosphere during the Jurassic period contained 130% oxygen, 7 times more carbon dioxide than before the industrial age, and temperatures were about 3°C higher than today.
Large mainosaur reptiles became dominant species. In the air, pterosaurs became common flying animals, occupying various ecological niches. In the late Jurassic period, the first birds appeared.
Fish and marine reptiles flourished in the Jurassic oceans, and marine reptiles at this time included: Ichthyosaurus, Plesiosaur, and Marine Crocodile (Ground Lizard Crocodile family and True Lizard Crocodile Family).
Cenozoic (65 million years ago – present)
Paleogene (6500-23.3 million years ago)
At the beginning of the Eocene, Australia and Antarctica remained connected, while warm equatorial currents merged into the cold Antarctic waters, allowing heat to be distributed globally, thereby maintaining high global temperatures. But 45 million years ago, when Australia split off from the southern continent, warm equatorial currents began to drift away from the Antarctic region, creating an isolated cold waterway between the two continents. The Antarctic region continued to cool, the Antarctic waters began to freeze, and cold water and sea ice were transported northward, further exacerbating the cold situation.
The northern supercontinent, Lauyagu, also began to split, with Europe, Greenland, and North America splintering off.
New Age (23 million – present)
The collision of Africa with Eurasia, the formation of the isthmus between North and South America and the formation of the isthmus between Asia and North America have led to the mixing, migration and contact of species that had been scattered in the past.
Twenty million years ago, Antarctica was completely covered in snow and ice, and the northern continent began to cool rapidly. The world looks very similar to what it is today, but parts of Florida and Asia are still covered by oceans.
Quaternary (2.6 million years ago to the present, incorporated into the Neogene period)
Most of the animal and plant species of this period are similar to modern ones, only a few new animal species have emerged (probably because this period is relatively short), and at the end of the Pleistocene, many mammals (such as saber-toothed tigers, mammoths, mammoths, mastodons, etc.) became extinct. Horses, camels, etc. became extinct in North America.
Climatic notability is characterized by cooling and a marked alternation of glacial and interglacial periods. During the glacial period glaciers can extend all the way to 40 degrees latitude. At this time, there were five major ice ages in Europe: the multi-brain ice age, the Qunzhi ice age, the Minde ice age, the Rees ice age and the Tamaki ice age.
