Cainozoic panguva

Era okukura Nyika anyanya yakasiyana akawanda. Vanosanganisira uye zvakasiyana nguva. The Cenozoic Era ndiye ichangoburwa Geological ichikosha. Kureba - makore mamiriyoni 65 .. The Cenozoic Era rakakamurwa zvitatu nguva: asi Anthropogenic, Neogene uye Paleogene. Mumwe nomumwe wavo, akavapindurawo, rakakamurwa epochs.

Cenozoic nguva uye mberi nhasi.

Paleogene inosanganisira Oligocene, Eocene, Paleocene, Neogene - Pliocene uye Miocene, Anthropogene - Holocene uye Pleistocene.

Sei upenyu muna Cenozoic yaitonga

65 mln. Makore akapfuura Paleogene kumwedzi.

First ichikosha ndiye Paleocene. Sezvo akatanga Cenozoic yaitonga. Panguva iyoyo, makondinendi vakaramba kufamba kwavo uye Gondwana (the Mainland kwazvo) akaramba rwakakamukana. Zvachose kubviswa kubva nyika zvakazoonekwa kuti South America.

On nyika mhuka vakatanga ichishanduka, mangwanani primates vaiva insectivores nemakonzo. Paiva vamiririri zvikuru zvose herbivores uye nezvikara. Marine mvura yakatanga kuva itsva mhando Sharks nezvimwe hove dzinodya dzimwe.

Pakati zvirimwa akatanga kuparadzira maruva marudzi.

Eocene yaitonga rakatanga makumi mashanu mamiriyoni apfuura. The yakaoma akatanga kugadzirisa pasi seizvi, sezvazvakaita nhasi. South America Haasisina kuti aishamwaridzana Antarctica, India vakatamirawo Asia. Vakatanga kupararira uye Australia kuna Antarctica.

On nyika paiva lemurs, zviremwaremwa, herbivores guru (madzitateguru mombe, namabhiza, nzou, nguruve, uye nezvimwe). Humwe howa mhuka uyewo vakashanduka.

Vakawedzera uwandu Freshwater hove, hove huru shure mumvura.

Takatanga miti kukura vakadzikama latitudes, masango akawanda akasiyana zvikamu akasvibirira zvinomera Wepasi.

Oligocene ichikosha vakatanga matatu namasere mamiriyoni apfuura. map Australian uye Antarctica inokamukana chose, sezvo India akayambuka Equatorial mutsetse. Okunze panyika vakava kutonhora. Yakakura chando chivharo yakaumbwa pamusoro South Pole. Izvi zvakaita kuti kuwedzera munyika nzvimbo, uye zvinoderedza mvura vhoriyamu. Maererano kutonhora akatsiviwa uye zvinomera. Panzvimbo yacho rainforest rakapararira inowanzorimwa.

Herbivorous mhuka vakatanga kushingaira kuva pamusoro inowanzorimwa munzvimbo. Kune mhando itsva hares, tsuro, chipembere, vamiririri ruminants okutanga.

makore makumi maviri nemashanu mamiriyoni ago Neogene kumwedzi. Zvinosanganisira epochs maviri.

Panguva Miocene, anenge ose makondinendi vakaramba kufamba. Somugumisiro ari kudhumhana Africa ne Europe uye Asia akaumba Alps. Mushure unobatanidza India uye Asia akaumba eHimalaya. Panguva iyoyowo, aine eAndes uye Rocky Mountains. Panguva iyoyowo Australian uye South America kondinendi akaramba kure nenyika. On ose kondinendi yakatanga nemamwe kasvisto yayo uye miti nemhuka zvakazonaka. Kupararira echando pepa iri Antarctica wakatsamwisa kunyanya kutonhora.

Panguva Miocene mhuka akatamira kubva kuendesa kune mumwe.

Makore mamiriyoni mashanu apfuura Pliocene akatanga.

The makondinendi anenge ari mumwe chete panzvimbo sezvo nhasi. Akaramba kutonhora uye kuparadzira steppes.

Herbivorous mhuka uye kushingaira yakatanga. Kushanduka bhiza. The nzvimbo yechizvarirwo hwemhuka ndiye North America. Kubva ipapo, mabhiza vakapararira mhiri nyika.

By kuguma Pliocene, North neSouth America vakava chokuita nomumwe. Maererano kuumba "nyika zambuko" akatanga kufamba mhuka kubva imwe kondinendi imwe. The vatsvakurudzi vanoti panguva ino paiva kutsakatika zhinji mhando nokuda zvinowedzerwa kutamburira vapone.

Makore mamiriyoni maviri apfuura, waitanga Anthropogenic nguva.

The ichikosha rokutanga - ari Pleistocene - dzinoratidzwa pakuparadzirwa chando. Panguva ino, rakatumbuka nguva kwepasi uye kutonhora, akazeza, uye pegungwa. Zvinofanira kucherechedzwa kuti kunyange iye zvino zvinhu zvakadai zvikaramba.

Zhinji mhando mhuka kunge dzakashandisa ekunze. vanhu vokutanga akazviratidza.

Vanenge zviuru gumi apfuura, pakutanga Holocene - Nguva Anthropogenic nguva wechipiri.

Climate akafanana ano, rakatumbuka nguva kutonhora uye kwepasi. Zvakatanga kukura rwevanhu.
