Arkeozpoikum it means period of life purba, the arkeozoikum ( arkean ) is the early formation of scaling rock earth then developed into protokontinen. Rocks of the period found in some parts of the world who customarily called palace / shield continent.
Let's look at this time period, is the formation of kerakbumi. So kerakbumi was formed after cooling down the edge of the Earth's u201Cbalon%% u201D (prospective candidates). Plate tectonic/tectonic plates that cause earthquakes were formed at this time. The environment is similar to that of course mas environment around the springs of hot water.
The oldest rocks recorded approximately 3.800.000.000 years. This period is also the beginning of the formation of Indrosfer and Atmosphere as well as the early primitive life emerged in the oceans in the form of micro-organisms (bacteria and algae). The oldest fossil that has been found is a fossil Stromatolites with Cyanobacteria and aged approximately 3.500.000.000 years.
The proterozoikum ( 2.5 billion � 290 million years ago )
Early Proterozoic time means life. The early Proterozoic is formation of hydrosphere and atmosphere. At this time of life began to grow from a single-celled organism into a many-celled (enkaryotes and prokaryotes). Enkaryotes this will be plants and prokaryotes would later become animals.
Before the end of this organism more complex, kind of invertebrates soft-bodied like jellyfish, worms and coral begin to appear in laut-laut shallow, the evidence be found as a fossil first true. The arkeozoikum and proterozoikum together known as the pra-kambrium.
Ages Of cambrium ( 590-500 million years ago )
The cambrian derived from the word � cambria � the latin name for the region of wales on british there, where was the cambrian rocks first learned.
Of many invertebrate animals begin to appear in the days of cambrian. Almost all life are in the ocean. This generation animal have outer skeleton and shell as a protection. Fossil common be found and their spread is broadly, algæ; cacing, sponge, coral, mollusks, ekinodermata, brakiopoda and arthropods ( trilobites ). An inland called gondwana ( formerly pannotia ) is service will antarctica, africa, india, australia, parts of asia and south america. While europe, north america, and green ground still in form of benua-benua small detached.
Ages of ordovisium ( 440-500 million years ago)
The Ordovician is characterized by the appearance of the fish without the jaw (the oldest vertebrate animals) and several vertebrate who appears first as Tetrakoral, Graptolit, Ekinoid (Sea Urchin), Asteroids (Starfish), Krinoid (sea-Lilies) and Bryozona.
Coral and Algae flourish forming reef, where the trilobite and Brakiopoda looking for prey. A rich Trilobite and Graptolit, while Ekinodermata and Brakiopoda began to spread. Ocean debris from the last ice age is part of events of this era. Gondwana and other continents began to close the gap of the ocean who are in between.
Ages of silur ( 440-410 million years ago )
Silur period is a transitional time of life from water to land. Land vegetation began to appear the first time including Pteridofita (ferns). While the giant Scorpion (Eurypterid) hunting life in the sea. Berahang fish are starting to appear in this era and many fish have a protective shield as a bone.

Ages of devon ( 410-360 million years ago )
The devonian is an era in which development of massive kinds of fish and terrestrial herbs. Fish berahang and sharks more active as predators in the ocean. The invasion to the mainland is still underway during these days. An amphibious animal of developing and headed for the mainland. Terrestrial herbs becoming as common and appearing insects for the first time. Samudera narrows meanwhile, gondwana cover europe, the continent north america and the land of green land )
Ages of carbon ( 360 290 million years ago )
Reptiles show up the first time and can lay their eggs out of water. Giant insects appear and ampibi increased in number. The first trees appeared, fungi, plants and groups ferm and horsetail grows in coal forming swamp. At the time of these continents on Earth fused forming a single landmass called Pangea period, experiencing a change in the environment for a variety of life forms. In the northern hemisphere, the tropical climate generates a massive, containing swamps and now stored as coal.
Ages of perm ( 250-210 million years ago )
Bivalves and gastropods are increasing in number, while amonit became common. Dinosaurs and large sea reptiles began to appear the first time during this period. Mammal-like reptiles called carnivorous Cynodont began to develop. Pertamapun mammals began to appear at this time. And there are many types of reptiles that live in the water, including turtles and tortoises. Sikada Palm-like plant growing and Evergreen spreading. The continent of Pangea moved north and deserts are formed. Southern ice sheets melted and the cracks begin to form in Pangea.
Ages of jurrasic ( 210-140 million years ago )
n the days of this amonit belemnit and very common. Reptiles increased in number. Dinosaurs master mainland, ichtiyosaurus hunting in the seas and pterosaurs major player space. Many dinosaurs grow in extraordinary size. Birds first true ( archeopterya ) evolved and many crocodile species growing. Herbs conifer being generalized, while bennefit sequola and abundantly in this time.
Pangea split where north american seceded from africa and south america disengage from the antarctic and australia
These days is the days of the most interesting the children after difilmkannya jurrasic park.
Ages of lime ( 40-65 million years ago )
Many of the giant flying reptiles and dinosaurs lived during this period. Mammals means-ari appeared the first time. At the end of this period the dinosaurs, Pterosaurs, Ichtiyosaurus, Belemnit, Amonit and Plesiosaurus extinct. Mammals and flowering plants began to develop into many different shapes. The climate is beginning to emerge. India despite far from Africa to Asia. This period is the last days of the life of biantang-giant beast.
Ages of tertiary ( 65 1 7 million years ago )
At the time of the tertiary type of developments occurred life like the emergence of primates and no large-sized toothed birds which resemble ostriches, while marine fauna, such as fish, molluscs and echinoderms are very similar to the marine fauna that lives right now. Flowering plants of tertiary period continue to evolve resulting in many varieties of plants, such as shrubs, vine and lawns. During the Quaternary, Tertiary% u2013 appearance and extinction of animals and plants are interchangeable as the weather changes globally
Ages of quarter ( 1 7 million years ago now )
The quaternary consisting of kala plistosen and holosen time.Plistosen time beginning about 1.8 million years ago and ends at 10,000 years ago. Later joined by holosen time that lasted until now.
In the days of old plistosen at least occurs five times the ice age ( the glacial ). In the glacial most of europe, north america and northern asian covered ice, so is the alps, the mountains cherpatia and the himalaya mountains between 4 the ice age that there are the an extern glacial, where the earth warmer climate.
Ancient Java man (Homo erectus who used to be called Pithecanthropus erectus) appeared on Kala Plistosen. Modern humans who had a new civilization emerges in Holocene Time. The Flora and fauna living on Kala Plistosen is very similar to the flora and fauna that lives right now.
