Palaeozoic

The Paleozoic Era bụ ogologo oge ogbo nke mmepe nke Earth. Ọ dịgidere 370 nde afọ.

Mgbe e guzobere nnukwu ebe ala dị na njedebe nke Proterozoic oge, ndị Palaeozoic oge malitere ọtụtụ ikwafu oké osimiri nile. Dị ka ọtụtụ ndị geologists, mgbe ọ na otu nnukwu ala ngọngọ na a na-akpọ Pangea ( "ụwa dum" na asụsụ Grik). On n'akụkụ niile ọ gbara oké osimiri. Na nke a na nnukwu ngọngọ da iche karịrị oge. N'ihi ya, Paleozoic oge bụ oge nke guzobere ntọala maka ọdịnihu nke Afrika.

The mbụ amụma nke "continental nwayọọ," kwuru Alfred Wenger (German geologist). Dị ka ya, ná mmalite, Pangea kewaa Gondwana na Laurasia.

The oge nke Paleozoic oge ekewa ndị Permian, Carboniferous, Devonian, Silurian, Ordovician na Cambrian (ndị kasị ochie).

Cambrian ogbo malitere banyere 570 nde. Afọ gara aga (dị ka ụfọdụ na isi mmalite, a obere tupu). Na oge nke oge a, nde 70. Afọ. The malite ogbo a ejikọrọ na evolutionary mgbawa na ụwa, nke e nwere bụ ndị mbụ nnọchiteanya nke kasị nke isi dị iche iche nke ụmụ anụmanụ na-mara taa.

Site na njedebe nke Ordovician ogbo malitere ga-ahọrọ na ala gbara osimiri okirikiri apịtị, decomposing ya, dịkwa ka usoro ha obodo nke algae, bacteria. N'ihi ya, ala oyi akwa kpụrụ oge ochie.

Ná mmalite nke Silurian azụ ada udi, nso n'oge a otu. Site na njedebe nke ogbo amalite orogenic Filiks. Dị ka a N'ihi ya, ha kpụrụ Cambrian, na Scandinavian ugwu na massifs na Eastern Greenland na South of Scotland.
