Cainozoic oge

Oge nke mmepe nke Earth kere a dị iche iche ọtụtụ afọ. Ha na-agụnye na dị iche iche oge. The Cenozoic Era bụ ọhụrụ geological epoch. Ogologo-ya - 65 nde afọ .. The Cenozoic Era ekewa atọ oge: na Anthropogenic, Neogene na Paleogene. Onye ọ bụla n'ime ha, n'aka, kewara epochs.

Cenozoic oge na-aga n'ihu taa.

Paleogene agụnye Oligocene, Eocene, Paleocene, Neogene - Pliocene na Miocene, Anthropogene - Holocene na Pleistocene.

Olee otú ndụ na Cenozoic oge

65 mln. Afọ gara aga na Paleogene oge.

First epoch bụ Paleocene. Ebe ọ bụ na ọ malitere Cenozoic oge. N'oge ahụ, ndị na-enye aka iso ha ije na Gondwana (oké Chile) wee na-kewaa. Ebechapu ya kpamkpam n'ebe ụwa tụgharịa si South America.

On n'ala mammals malitere webata, n'oge primates ndị insectivores na òké. E nwere ndị isi ndị nnọchiteanya nke ma herbivores na anụ. Na mmiri mmiri wee malite ọhụrụ umu nke umu azu shark na ndị ọzọ na-eri azụ.

N'etiti osisi malitere ịgbasa okooko umu.

Eocene oge malitere iri ise na ise nde afọ gara aga. The Chile malitere dajụọ ka nke a, dị ka ọ dị taa. South America akwụsịla na-metụtara ndị Antarctica, India nwekwara kwagara Asia. Malitere ịgbasa na Australia ka Antarctica.

On n'ala e nwere lemurs, ụsụ, nnukwu herbivores (nna nna nke ehi, ịnyịnya, enyí, ezì, na ndị ọzọ). Ọzọ umu anumanu nwekwara ghọrọ usoro.

Ọnụ ọgụgụ ka elu nke freshwater azụ, whales azụ n'ime mmiri.

Anyị malitere na-eto eto osisi na ọnọdụ latitudes, oké ọhịa nke ọtụtụ dị iche iche nke ụwa na-lush ahịhịa.

Oligocene epoch malitere iri atọ na asatọ nde afọ gara aga. Australian Afrika na Antarctica kpamkpam ekewa, dị ka India gafere Equatorial akara. The idụhe na mbara ala ghọrọ oyi. Sara Mbara ice okpu kpụrụ n'elu South osisi. Nke a emeela ka mmụba nke ala ebe, na Mbelata mmiri olu. Na njikọ na jụrụ dochie na ahịhịa. Kama na ohia mmiri ozuzo na-agbasa steppe.

Herbivorous mammals malitere ifịk ifịk ịzụlite na steppe ebe. E nwere ọhụrụ iche iche nke hares, òké Bekee, enyí ọhịa, mbụ nnọchiteanya nke ruminants.

Iri abụọ na ise nde afọ gara aga na Neogene oge. Ọ na-agụnye abụọ epochs.

N'oge Miocene, fọrọ nke nta niile kọntinent wee na-akpali. Dị ka a n'ihi nke nkukota of Africa na Europe na Asia kpụrụ Alps. Mgbe ejikọta India na Asia kpụrụ Himalayas. N'otu oge ahụ, na-enwe ndị Andes na Rocky Ugwu. N'otu oge ahụ Australian na South America Afrika nọgidere dịpụrụ adịpụ site n'ụwa. On bụla mepụtara ya nwere ihe pụrụ iche na osisi fauna. Mgbasa nke ice mpempe akwụkwọ na Antarctica kpasue ọbụna ihe jụrụ.

N'oge Miocene anụmanụ kwagara si onye Afrika ọzọ.

Nde ise afọ gara aga malitere Pliocene.

The kọntinent ndị fọrọ nke nta na otu ebe dị ka taa. Wee jụrụ na nkesa nke steppes.

Herbivorous mammals na ifịk ifịk mepụtara. The evolushọn nke ịnyịnya. The omumu nke anụmanụ bụ North America. Site n'ebe ahụ, ịnyịnya na-agbasa gafee planet.

Site na njedebe nke Pliocene, North na South America wee jikọọ na onye ọ bụla ọzọ. Dị ka na-etolite a "ala akwa" malitere ije nke ụmụ anụmanụ si onye Afrika ọzọ. The na-eme nnyocha na-egosi na n'oge a, e nwere ikpochapu nke ọtụtụ ụdị n'ihi na nke aggravated mgba maka nlanarị.

Nde abụọ afọ gara aga, ọ malitere Anthropogenic oge.

The mbụ epoch - na Pleistocene - ji mgbasa nke ice mpempe akwụkwọ. N'oge a, e nwetụ oge okpomọkụ na obi jụrụ, azụ, na oké osimiri. Ọ ga-kwuru na ọbụna ugbu a dị otú ahụ a ọnọdụ nọgidekwara.

Ọtụtụ anụmanụ umu-emegharị ka idụhe. ụmụ mmadụ mbụ pụtara.

Iri puku afọ gara aga, na-amalite nke Holocene - nke abụọ oge nke ndị Anthropogenic oge.

Climate yiri oge a, e nwetụ oge jụrụ na-ekpokwu ọkụ. Ọ malitere na mmepe nke agbụrụ mmadụ.
