Palaeozoic

The Paleozoic Nyengo yaitali siteji zokwanira chitukuko ya Earth. Zinatha zaka miliyoni 370.

Pambuyo mapangidwe m'madera ambiri m'dziko kumapeto kwa nyengo Proterozoic, ndi Palaeozoic nyengo anayamba yaikulu litulukira nyanja. Malinga Akatswiriwa ambiri, pamene panali yaikulu m'dziko chipika wotchedwa Pangea ( "dziko lonse lapansi" mu Chigiriki). Kumbali zonse wazunguliridwa ndi nyanja. Ndi chipika yaikuluyi unatha nthawi. Motero, nyengo Paleozoic Nthawi mapangidwe maziko tsogolo m'dzikoli. Pa pofuna kukwaniritsa Dziko Lapansi, mbali awa akhoza kuchuluka, kulumikiza (ndondomeko orogenic) kapena kuchepa, kuswa zidutswa kachiwiri, chimene chikanakhoza sakukondananso mpaka nthawi sinafike wotanganidwa malo a m'mayiko pano.

The kungoganizira loyamba "kulowerera chokhala," anatero Alfred Wenger (German miyala ndi nthaka). Malinga ndi iye, poyamba, Pangea unagawika Gondwana ndi Laurasia.

Nthawi ya nyengo Paleozoic lagawidwa ndi Permian, Carboniferous, Devonian, Silurian, Ordovician ndi Mathanthwe (wamkulu).

siteji Mathanthwe unayamba pafupifupi miliyoni 570. Zaka zapitazo (monga ena amanena, pang'ono kale). Kutalika kwa nthawi imeneyi, 70 miliyoni. Zaka. Mbali kuyambira chikugwirizana ndi kuphulika zamoyo zinachita mu dziko, chimene anali oyimira woyamba ambiri a magulu akuluakulu a zinyama zimene zimadziwika lero.

Malire a Precambrian ndi Mathanthwe anamuona pa miyala, pamene mwadzidzidzi pali yaikulu zosiyanasiyana nyama zakufa zakale ndi mafupa mchere. Mathanthwe zamoyo zinachita kuphulika ndi chimodzi cha zinsinsi za mbiri ya dzikoli. Kupita losavuta maselo eukaryotic (kwambiricho) panatenga zaka mamiliyoni awiri ndi theka. Kwa zaka mamiliyoni 700. Panali multicellular choyamba. Ndipo oposa 100 miliyoni. Zaka dziko njuchi zosiyanasiyana zosaneneka za nyama. Tikumbukenso kuti kuyambira nthawi (zaka zoposa 500 miliyoni) mu dziko analibe nyama ndi dongosolo wachibadidwe latsopano la thupi.

Ordovician . Pafupifupi mamiliyoni 500 zaka zapitazo ndinayamba ndipo zinatha -. Pafupifupi miliyoni 408 zaka zapitazo.

Ambiri a Chigawo cha kum'mwera anatenga Gondwana. m'madera ena yaikulu ya dzikolo anali anaikira mu zone ya kunyanja. Nyanja pamene anthu nyama zambiri, ndi wosiyana kwambiri ndi anthu a nyanja za Mathanthwe ndi. Dzikolo linali pafupifupi zosafunika moyo - panalibe dothi, palibe zomera, mphalapala yotentha dzuwa, nthawi zambiri mphepo ndi kuphulitsa mapiri.

Pakutha siteji Ordovician anayamba kusankhidwa mu matope m'mphepete mwa nyanja, decomposing izo, bowa gulu la algae, mabakiteriya. Choncho, wosanjikiza dothi anapanga achikale.

Kumayambiriro kwa nsomba Silurian inkayenda, pafupi mmodzi ano. Pakutha siteji kuyamba ndondomeko orogenic. Chifukwa, iwo anapanga Mathanthwe, mapiri Scandinavia ndi mitandadza kum'mawa Greenland ndi South wa Scotland.

Devonian siteji chitukuko cha Dziko Lapansili amakhala ndi ngozi zoopsa kwambiri pa dziko. Pa nthawi imeneyo, panali zipolowe za Greenland, Europe ndi North America. Iwo anapanga kontinenti yaikulu Laurasia.

Carboniferous nthawi (mpweya CHIKWANGWANI) yodziwika ndi nyengo zosiyanasiyana - kusintha anabwera kuchokera m'ma kuti atumwi. Komabe, ambiri, izo (nyengo) ankasiyana chinyezi kotentha, subtropical ndi otentha woyendera nthambi. Izi analenga zinthu yabwino kwa kufala kwa chithaphwi ndi zomera nkhalango pa dziko.

Moyo Paleozoic nyengo unakhazikitsidwa wokangalika mpaka kumapeto kwa gawo lotsiriza.

miliyoni 299. Zaka zapitazo, anayamba chomaliza cha Paleozoic. Pa malire a nthawi Triassic anali zochuluka kwambiri mu mbiri ya mitundu ikutha pulanetiyo. Panthawi imeneyi, yasowa 70% dziko ndi 90% ya zamoyo m'madzi. Choncho anathetsa nyengo Paleozoic.
