Palaeozoic

I Paleozoic Era lide esiteji ngokwanele yentuthuko Zomhlaba. Lo mbuso waqhubeka ubusa iminyaka eziyizigidi ezingu-370.

Ngemva kumiswa izindawo enkulu yezwe ekupheleni kwenkathi Proterozoic, inkathi Palaeozoic waqala olubanzi imidlalo kwezilwandle. Ngokwezazi zokwakheka komhlaba eziningi, kuyilapho kwakunebandla elilodwa elikhulu ezweni block libizwa Pangea ( "wonke umhlaba" ngolimi lwesiGreki). Kuzo zonke izinhlangothi lizungezwe izilwandle. Nale block omkhulu waphela ngokuhamba kwesikhathi. Ngakho, kwenkathi Paleozoic kwaba nesikhathi kumiswa izisekelo lekusasa kuleli zwekazi. Phakathi ukuqhubeka Earth, lezi izingxenye zazingase zithuthwe yanda, ukuxhuma (ngokusebenzisa izinqubo orogenic) noma ukwehla, breaking zibe izicucu futhi, okungase bayaqhelelana kuze kube ngomzuzu ongakabi matasa yokuma amazwekazi zamanje.

Umbono wokuqala "ukugudluka kancane kancane kwamazwekazi," kusho u-Alfred Wenger (sokuma German). Ngokusho kwakhe, ekuqaleni, Pangea ahlukaniselwe Gondwana futhi Laurasia.

Izinkathi kwenkathi Paleozoic luhlukaniswe Permian, Carboniferous, Devonian, Silurian, Ordovician futhi eCambria (omdala).

isigaba eCambria waqala cishe izigidi ezingu-570. Eminyakeni eminingi edlule (ngokuvumelana kweminye imithombo, kancane ngaphambili). Isikhathi salesi sikhathi, abayizigidi ezingu-70. Iminyaka. Isigaba isiqala ixhunyiwe ekuqhumeni yokuziphendukela kwemvelo emhlabeni, lapho kwakukhona abameleli lokuqala iningi amaqembu amakhulu ezilwane latiwako namuhla.

Umngcele kamasipala Precambrian futhi eCambria ebonwe amatshe, lapho ngokungazelelwe kukhona omkhulu ezihlukahlukene isilwane izinsalela zamathambo nge amathambo amaminerali. ECambria ukuqhuma yokuziphendukela kwemvelo ingenye izimfihlakalo emlandweni womhlaba. Ukuya elula kumaseli eukaryotic (eziyinkimbinkimbi) kwathatha iminyaka emibili nengxenye million. Ngokusebenzisa kwezigidi ezingu-700. Iminyaka kwakukhona ezinamangqamuzana amaningi kuqala. Futhi angaphezu kwezigidi ezingu-100. Iminyaka le planethi ababengaphansi kwemibuso yakwamanye amazwe ezihlukahlukene Amazing izilwane. Kumele kuqashelwe ukuthi kusukela ngaleso sikhathi (iminyaka engaphezu kwezigidi 500) emhlabeni ayinazo isilwane kokuba isakhiwo ngokuyinhloko entsha umzimba.

Ordovician . Eminyakeni engaba ngu-izigidi ezingu-500 edlule waqala futhi yaphela -. Balinganiselwa ezigidini ezingu-408 edlule.

Iningi Nenkabazwe eningizimu wathatha Gondwana. Okunye izindawo ezinkulu zwe babaziwa bagxila kule zone enkabazwe. Sea ngenkathi kuhlale izilwane eziningi, ihluke kakhulu kusukela abakhileyo kwezilwandle we eCambria. Izwe lalingaphansi cishe engafanele ukuphila - kwakungekho inhlabathi, kungekho izitshalo, waphakamisela ukuhanguka ilanga, ngokuvamile neziphepho kanye nokuqhuma kwezintabamlilo.

Ngu ekupheleni Ordovician esiteji laqala ukukhethwa odakeni ugu, ezibolayo ke, isikhunta umphakathi ulwelwe, ama-bacterium. Ngakho, ungqimba inhlabathi kwakheka lasekuqaleni.

Ekuqaleni izinhlanzi Silurian wathatha ijamo, eduze eyodwa yesimanje. Lwathi luphela esigabeni uqale izinqubo orogenic. Ngenxa yalokho, benza kumiswa eCambria, ezintabeni zaseScandinavia futhi massifs e-Eastern Greenland kanye South yeScotland.

yentuthuko esiteji Devonian Zomhlaba libhekene izinhlekelele enkulu emhlabeni. Ngaleso sikhathi, kwaba khona Ukungqubuzana Greenland, aseYurophu naseNyakatho Melika. It akha zwekazi elikhulu Laurasia.

isikhathi Carboniferous (carbon fibre) libhekene sezulu ahlukahlukene - ushintsho lwaba wangekhulu ekhulwini. Nokho, ngokuvamile, ke (sezulu) kwahluka zinomswakama athokomele, nakwezifudumele futhi ezishisayo zone. Lokhu zadala isimo esihle sokwanda kwezindaba marsh futhi ihlathi izimila ezisezweni.

Ukuphila Paleozoic inkathi kwamiswa okhuthele kuze kube sekupheleni esigabeni sokugcina.

abayizigidi ezingu-299. Eminyakeni eminingi edlule, kwaqala iMpi ngxenye yokugcina Paleozoic. Emngceleni kwesikhathi Triassic kwaba yakhula kakhulu emlandweni zilwane yokuqothulwa emhlabeni. Ngalesi sikhathi, wanyamalala mayelana 70% ezweni futhi u-90% eziphilayo zasolwandle. Yaphela kanjalo-ke inkathi Paleozoic.
