Zaman Cainozoic

Era of horumarinta dhulka socday dhowr ah oo kala duwan oo sano. Waxaa ka mid ah iyo waqtiyo kala duwan. Cenozoic Era waa Epoch ugu dambeeyey ee dhulka. Oo dhererkeedu wuxuu - 65 milyan oo sano .. Cenozoic Era wuxuu u qaybsan yahay saddex muddo:, aadmiga ah Neogene iyo Paleogene. Mid kasta oo iyaga ka mid ah, oo iyana, qaybsan xilliyo.

Zaman Cenozoic oo socota illaa maanta.

Paleogene ka mid ah Oligocene, Eocene, Paleocene, Neogene - Pliocene iyo Miocene, Anthropogene - Holocene iyo Pleistocene.

Sidee waa nolosha xilligii Cenozoic ah

65 Years Million. Ago muddo Paleogene ah.

Epoch First waa Paleocene. Tan iyo markii la bilaabay xilligii Cenozoic. Waqtigaas, qaaradood ka sii dhaqdhaqaaqa iyo Gondwana (waynaha weyn) sii waday in ay kala jabeen. Gabi ahaanba laga gooyaa dunida soo baxay South America.

On nuujiya dalka bilaabay inuu xuubsiiban, iyo koroowga hore ahaayeen insectivores iyo jiirka. Waxaa jiray wakiilada ugu weyn ee geedo daaq iyo bahal labadaba. In biyaha badda bilaabay si loo horumariyo noocyada cusub ee galayaan iyo kalluunka kale ee ugaadhsiga.

Ka mid ah dhirta waxay bilaabeen in ay ku faafaan noocyada ubax.

Zaman Eocene bilaabay shan iyo konton milyan oo sano ka hor. dhulweynaha ayaa bilaabay in ay u xasil sidan oo kale, siday maantadan tahay. South America ayaa joojiyeen in allabaryo la xidhiidha Jacaylku, India ayaa sidoo kale u dhaqaaqay Asia. Waxay bilaabeen in ay kala eryaan iyo Australia si Jacaylku.

On dalka waxaa jiray lemurs, fiidmeerta, geedo daaq weyn (awoowayaasha lo'da, fardaha, maroodi, doofaarka, iyo kuwa kale). noocyada kale ee xoolaha ayaa sidoo kale waxaad fartaan Wannaagga.

Tirada sii kordhaya ee biyaha saafiga ah kalluunka, nibiriyada badda oo dib oo biyaha ku shubaa.

Waxaan bilaabay in geedo sii kordhaya ee latitudes qoraxda, kaymaha ee qaybo badan oo kala duwan oo ka mid ah dhulka daaqsinka xaqse.

Oligocene Epoch bilaabay siddeed iyo soddon milyan oo sano ka hor. Qaarada Australia iyo Jacaylku gebi ahaanba u qaybsan yahay, sida India xariiqda Equatorial. Cimilada caalamka noqday meeldhexaadka ah. cap baraf baaxad weyn sameeyay South reer Poland. Tani waxa ay keentay in la ballaariyo degaanka dalka, iyo hoos u ah mugga biyaha. In xidhiidh la leh qaboojinta la bedelay iyo Daaq. Halkii qaten steppe faafinta.

nuujiya Herbivorous bilaabay inuu si firfircoon horumarinta meelaha steppe ah. Waxaa jira noocyo cusub oo bakeylaha, bakaylaha, wiyisha, wakiilada koowaad ee ariga.

Shan iyo labaatan milyan oo sano ka hor xilliga Neogene ah. Waxaa ka mid ah laba xilliyo.

Inta lagu guda jiro Miocene ah, ku dhowaad dhammaan qaaradaha ka sii waday in ay u guuraan. Sidaas darteed of shil ee Africa la Europe iyo Asia sameeyay Alps. Ka dib markii xira India iyo Asia sameeyay Himalayas. Isla mar ahaantaana, isagoo Mountains geedka kokaha iyo Rocky ah. Isla mar ahaantaana qaarada Australia iyo South American hadhay go'doon ka dunida. On qaarad kasta horumariyo flora gaar ah u gaar ah iyo dubato. faafidda baraf on Jacaylku ka cadhaysiiseen qaboojinta xitaa ka sii badan.

Inta lagu jiro xayawaanka Miocene guuray ka mid ah qaaradda in kale.

Shan milyan oo sano ka hor bilaabay Pliocene.

qaaradood ayaa ku dhow yihiin meel la mid ah sida maanta. qaboojinta Continued iyo qaybinta deel ah.

nuujiya Herbivorous iyo si firfircoon uga horumarsan. horumar ah ee faraska. ku dhashay ee xayawaanka waa North America. From waxaa jira, oo fardahana ugu sii faafin guud ahaan caalamka.

By dhamaadka Pliocene ah, North iyo South America ayaa noqday mid ku xiran kasta oo kale. Sida laga soo xigtay si ay u sameeyaan a "buundada dalka" ayuu ku bilaabay dhaqdhaqaaqa xoolaha ka mid ah qaaradda in kale. Cilmibaadhayaasha ayaa soo jeedinaya in waqtigan waxaa jiray eynu ee noocyada badan sababtoo ah halganka daran ay u noolaadaan.

Laba milyan oo sano ka hor, waxay bilaabeen muddada aadmiga.

Epoch ugu horeeya ee - Pleistocene ah - gartaa faafidda sheet barafka. Wakhtigan, talantaalli ah muddo of kululaaneysa iyo qaboojinta, nahey, iyo heerka badda. Waa in la ogaadaa in xitaa hadda xaaladda noocan oo kale ah sii socoto.

noocyada xoolaha badan ayaa ku habboon cimilada. aadanuhu ugu horeysay u muuqday.

About toban kun oo sano ka hor, laga bilaabo of Holocene ah - Zaman labaad ee muddada aadmiga.

Cimilada ekaa casriga ah, talantaalli ah muddo of qaboojinta iyo kululaaneysa. Waxaa bilaabay horumarinta tartanka aadanaha.
