the Age of the Earth lasted a different number of years.They include a variety of periods and.The Cenozoic Era is the most recent geological epoch.Its duration - 65 million. Years.The Cenozoic Era is divided into three periods: the Anthropogenic, Neogene and Paleogene.Each of them, in turn, is divided into epochs.
Cenozoic era continues today.
Paleogene period includes Oligocene, Eocene, Paleocene, Neogene - Pliocene and Miocene, anthropogenic - Holocene and Pleistocene.
How is life in the Cenozoic era
65 million. Years ago the Paleogene period.
first epoch was the Paleocene.Since it began Cenozoic era.At the time, the continents continued their movement and Gondwana (the great Mainland) continued to split.Completely cut off from the world turned out to be South America.
On land mammals began to evolve, early primates were insectivores and rodents.There were major representatives of both herbivores and predators.In marine waters began to develop new types of sharks and other predatory fish.
Among the plants began to spread flowering species.
Eocene epoch began fifty-five million years ago.Main continents began to settle down like this, as it is today.South America has ceased to be associated with Antarctica, India also moved to Asia.Began to diverge and Australia to Antarctica.
On land there were lemurs, bats, large herbivores (ancestors of cows, horses, elephants, pigs, etc.).Other animals are also evolved.
increase the number of freshwater fish, whales back into the water.
start growing trees in temperate latitudes, forests in many parts of the Earth differed lush vegetation.
Oligocene epoch began thirty-eight million years ago.Australian continent and Antarctica is completely divided and India crossed the equatorial line.The climate on the planet became cooler.The vast ice cap formed over the South Pole.This has led to the expansion of the land area and a decrease of water volume.In connection with the cooling was replaced and vegetation.Instead of the rainforest spread steppe.
Herbivorous mammals have been actively developed in the steppe areas.There are new kinds of birds, rabbits, rhinos, the first representatives of ruminants.
Twenty-five million years ago the Neogene period.It includes two epochs.
During Miocene almost all continents continued to move.As a result of the collision of Africa with Europe and Asia have formed the Alps.After connecting India and Asia formed the Himalayas.At the same time it appeared the Andes and the Rockies.At the same time Australian and South American continent remained isolated from the world.Each continent has developed its own unique flora and fauna.Distribution of the ice sheet on Antarctica provoked even more cooling.
During Miocene animals migrated from one continent to another.
Five million years ago began Pliocene.
continents were located practically in the same places that today.Continued cooling and distribution of the steppes.
herbivorous mammals and actively developed.The evolution of the horse.The homeland of this animal is North America.From there, the horses spread across the planet.
the end of the Pliocene North and South America became connected with each other.According to form a "land bridge" began the movement of animals from one continent to another.The researchers suggest that this time was the extinction of many species because of the aggravated struggle for survival.
Two million years ago, it started the Anthropogenic period.
first era - the Pleistocene - characterized by the spread of the ice sheet.At this time, alternating periods of warming and cooling, and sea level fluctuated.It should be noted that this situation is now stored.
Many animal species have adapted to the climate.There were the first people.
About ten thousand years ago beginning of the Holocene - the second era of the Anthropogenic period.
climate resembled modern, alternating periods of cooling and warming.It began development of the human race.
