Ordovician wā o ka Paleozoic au hou: flora a? Aaoa

Ordovician (nenoaiu) - i ka lua o ka papa o sediments o ka Paleozoic pae i loko o ka mōʻaukala o ka geology o ka Honua. Ka inoa ua loko mai o kaʻohana kahiko o ka Ordovician. Ka mea, i noho ai i loko o Wales, UK. Keia manawa ua ike ia he kuokoa kahua. Ua ola elima haneri miliona makahiki aku nei, a he mea kanaono miliona makahiki. Ka manawa i anao? Aou no ka hapanui o keia mau mokupuni, a ma luna o nā mea a pau âinapuni.

Geology Ordovician System

I ka hoʻomaka o ka wā o ke Akau, a America South ua Ua kokoke i Europa, a Africa. Australia ua hiki mai me Aferika, a ua hapa o Asia. Kekahi o nāʻauamo i loko o ka'ākau hapa o Aferika, ka mea 'ē aʻe - i loko o ka akau loa o ka Moana Pākīpika. I ka hoʻomaka o ka Ordovician nui o ka hema o ka Honua noho i ka'āinapuniʻole Gondwana. Ua komo kaʻikena South America, South 'Akelanika, Australia, Aferika, North Asia a me ka Indian Ocean. Ua, 'Eulopa a me North America (Lawrence) ua lilo kaawale mai kekahi i kekahi. Sea Hawaiʻi 'ilikai. Ka hapa nui o ka'āina i loko o ka mehana lakikū. I Gondwana i hoʻouku, a me ka hope o ka Hawaiian hauneneʻe. I South America, a ma ka akau-komohana Africa koe lalo sediments o moraines, i haʻalele i ka Paleozoic'āina.

Ordovician i loko o ka Arabia Peninsula, ma ka hema o Farani, Spain ua wehewehe aku ma ka icing. I Brazil a West Sahara ko läkou 'o ka hau i loaa. ? Anoe? O ke kai, iaono? Ana i loko o ka waena Ordovician. Ma ke komohana o māhele o Kona Akau a me America Hema, Beritania Nui, ma ka Ural-Mongolian kāʻei, ma ka hema-hikina o ka Australia, ko läkou 'o Ordovician sediments a hiki i ka umi tausani mau mika. Ma kēia mau wahi, he mau he hailona o ka lua pele, ka pele hoʻonui strata. E huli i kekahi chert: iasepi, ftanidy. Ma Rusia ka Ordovician wā mea maopopo hiki ma ka hikina Europa, Siberian anuu, i loko o nā Urals, Novaya Zemlya, ma luna o ka New Siberian Pae Aina, ma ka Taimyr Peninsula ma aneea oneiaey, a Central Asia.

Climatic kulana home 'ole i loko o ka Ordovician System

I Ordovician aniau Ua maheleia i eha hoailona ia mea: Tropical, pakiko, subtropical, nival. Ma ka Late Ordovician i anuanu. Ma Tropical wahi o ka mahana, haule iho ma ka elima degere, ma subtropical wahi - umikumamalima. Loa loa anu i loko o ka lakikū kiʻekiʻe. The Middle Ordovician ua he 'Ākau aniau, like me ka mea mua'āina. Kēia proves hoi o ka makana limestone.

Nā minelala hao i loko o ka Ordovician System

Mawaena o na nā minelala hao i hanaʻia i loko o kēia wā, ola ka aila a me ka kinoea. Oi loa aku hoi i ka puu o ka hoʻokomo kālā o kēia wā i loko o North America. Kekahi kahiāuli i ka waiho o ka aila shale, phosphorite. Mau hoʻokomo kālā i wehewehe ia e 'ā ina keʻano o ka hanaʻana i loko o ka pelemaka a i' ole. No ka laʻana, ma aneea oneiaey he mau hoʻokomo kālā o manganese i eliia, a barytes.

Kai i loko o ka Ordovician

The Middle Ordovician he mea he anoe o malina hakahaka. Seabed i lalo. Mau loli nui loli i ka hoʻomāhuahua o ke ahu nui o ka sediment, a i na poe eʻeleʻele sludge. Ua ninoieo o ka lehu pele, clastic pohaku a me ke one. pāpaʻu kai i ke aupuni 'o ka mea manawa North America a meʻEulopa.

Nā flora a? Aaoa o ka Ordovician

ka wā hoʻohālike au i ka mua wā līoho i loko o ka Ordovician manawa i i loli. Eia kahi mea akaka i ka mea kanu loa mua ma luna o ka honua nei. Ka mea, i ka hapanui poe e mosses.

Life i loko o ka wai i loko o kēia wā o kona kulana like. I ka mea kumu ka mea, ua noʻonoʻo nui loa i loko o ka mōʻaukala o ka Honua. I hana i ka papa kuhikuhiEʻano o ka moana mea. Aia nō i ka iʻa mua. Wale ka mea, ua uuku loa, ma kahi o elima mau kenimika. Ma kai hoomaka mea e hōʻike paakiki poi. Ua ua no ka mea, ola meaola hoomaka ae la e ala hou ma luna o ka lalo sediments, a hānai ma luna o ka seabed. More a oi ma laila mea i ka holoholona i hānai i loko o ke kai. Ua loli Hawaiʻi kekahi pūʻulu o vertebrates, 'ē aʻe i pono hoʻomaka e hoʻomōhala. I ka pau ana o ka Ordovician ikea vertebrate meaola. Mai ke echinoderm kai Oe ikeia oia, kai līlia. Currently, na meaola i kai lilia, a kai hoku no hoi nei.

Ma luna o ke kai lilia lana hipa o ka jellyfish - keia mea he nani kiʻi o nā manawa kahiko. i na mea nona e hoomaka ana e poho kā lākou 'eleu. Gastropods a elasmobranch poe ma ka helu nui o? Ueo. Ma ka Ordovician cephalopods chetyrehzhabernyh? Acaeoey ia lŘlŘ - he primitive laʻelaʻe 'ia Nautiloidea. Mau meaola i manawa e noho ana i loko o ka hohonu o ka moana Indian. E poholo kahiko 'elele o kēia mau mea e noho ana, ua pololei, i kue i ka uma leho o kēia nautilus? Ueo. Mau clams lakou i ka Moana Aloha Hawaii.

New holoholona i loko o kēia wā, he graptolites. Ka mea, paʻi ma ka opuu ae. Graptolites hana panalāʻau. Mua, ua haawiia ka mea, i na coelenterates, manawa - e krylozhabernym invertebrates. I keia manawa, graptolites e ola, akā, ma laila nō lākou mamao hoahanau. Kekahi o ia mau mea ola i loko o ka North Sea - o Rhabdopleura normanni. No hoi, aia no he pūʻulu o ka meaola i kōkua punakea, kūkulu papa. Ka mea iʻikeʻia i kēia manawa - ia bryozoans. Ka mea, i kahi e, e like mau meaola ma luna o ka nani uliuli lāʻau liʻiliʻi. E ia iloko aromorphoses Ordovician i ka noho ana meaola.

Nā poʻe e noho ana ma na kai

Ke sandstone ma Hawaii koena ai i loaʻa jawless ka iʻa. Extracted a me nā residues o vertebrate mea, like me ka mano. Fossils hōʻike i ka Ordovician jawless kekahi mau mai i keia la ka? Ueo.

Ka mua holoholona i ua mau niho - ia conodonts. Mau mea i like i ka huehue. Kā lākou mau mea okoa, mai na ā o ola mea. ʻepekema, ua manaʻoʻiaʻeono haneri a laha 'o ola mea i noho i loko o na kai i loko o ka luna wā. Ke anu Snap i kekahi o na kumu no ka ia'na o na mea he nui? Ueo. Ua lilo i ka pāpū pāpaʻu kai, a make ihola nā holoholona o ke kai. Ka Ia hopena ua kūkulu aʻela, a? Aaoa o kēia wā.

Ke kumu no ka ia'na o ka holoholona meaola

Aia he nui aku o ka nui ia'na o ka mea:

1. Lele aku o ka gamma na kukuna loko o ka poe lń.
2. I ka haule ana o na moanawai nui, mai ka lewa. Lākou mau koena ai a meteorites i loaʻa ai i kēia lā.
3. Ka hopena o ka ho okumu o ka mauna nenoai. pöhaku i ke anilā ma ka makani a me ka loko o ka lepo. E like me ka hopena o kēia mau keʻano o ka hanaʻana mea haʻahaʻa ma ka kalapona, i loli ai ka mehana ponoʻana aʻe.
4. Neʻe maila Gondwana i ka South Pole alakai i ke anu Snap, a laila, i ka hau makahiki, he ka ho'ēmiʻana o ke kiʻekiʻe o ka wai i loko o ka moana.
5. Ke saturation o ko ke ao nei i ka moana ke hooheheeia. Aʻo plankton ia manawa he kiʻekiʻe pae o keʻano o ke hooheheeia. Wai kaʻapu kōheoheo mai ai ke hooheheeia.

I o kēia mau XAaOOEN mea credible, a no ke aha la i mea ole holoholona Ordovician, ua a ianoiyuaa a ike ole.
