Life ma ka Honua i loko o ka Cretaceous au

Cretaceous wā o ka hope au, o ka hope loa Mesozoic'āina. He Ua pomaikai ma ka Canyon, e like me ka helu o nā kanaka hulihonua, ma kahi e puni 145 miliona makahiki aku nei, a he mea e pili ana i kanawalu miliona makahiki, ma hope i ka hoʻomaka o ka Tertiary wā mea okoa, o ka Cenozoic, i ke au - ". I ke au o ke hou ola i kekahi" I ka inoa o keia kahuaʻano lōʻihi o? Acaeoey o ka Honua i loaa mai ma ka pili ana i ka mea āna i haʻalele ai iā mākou i ka hoʻoilina o ka ikaika chalk hoʻokomo kālā o ka marl a me ke one. 'Oiai, i kēia mau makahiki miliona makahiki ma ka Honua i ole i hoʻomaka ai i kekahi hewa ma luna o kekahi planetary pālākiō, a nolaila, i ka ia'na o ka helu nui o ka mea kanu a me nā holoholona laha', aka, i ka neʻeʻana o ka una honua, ka loli ma global 'ilikai a me ka huliau ua i na hoololi i loko o ke kaʻina hana o ka evolution o ka poʻe e ola ana mea .

Cretaceous e subdivided i loko o iiaciiie-na pauku: ka lalo a me luna chalk. E maopopo pehea ola Hawaiʻi i loko o nā kai, ma luna o ka'āina, a ma ka lewa o ka manawa, e pono e nana pokole i emi iho i ka hooholo, mahope mai o ka Canyon ke kahua una orogenic keʻano o ka hanaʻana. I ka lalo cretaceous au mai o Gondwana a me Laurasia i ka hoʻoneʻeʻana aku, mai kekahi i kekahi. Penei nōʻo ia kaʻina hana ana me Aferika a me Amerika Hema. Ke'ī mai, i ka 'Akelanika' ua lilo increasingly kama'āina iā mākou e outline. Akā, ma ka hikina o Gondwana ia merged me Laurasia. Australia i kahi e noho, a me ka manawa, akā, i ka wai ala wale i ka hapakolu o ka keia wahi.

Luna Cretaceous ua wehewehe aku ma ka mea i loko o ka'ākau hemisphere hoomaka kai pae e alaʻi, a me nā'āpana o ka hikina 'Eulopa, Western Siberia, i ka pau o Arabia, a kokoke e pau i kēia Canada, he ma lalo o ka wai. Eia naʻe, ma ka hopena o ka Cretaceous wā o ka Honua, hoomaka ae la e hoohalike ai kona helehelena kēia poepoe honua.

Ma ka Cretaceous wā i ua loli a me ke aniau. He, o ka papa, ua nui kai mehana ma mua o kaʻiʻo nō o kēia. Ua uhi Space o keia la ka Europe me ka Tropical nani. Eia naʻe, ma kiʻekiʻe lakikū ua koho 'ē aʻe kau, a me ka hooilo snowfall. Oia ka huliau i ala i ka mea e, a me ka spore a me gymnosperms ikea zakrytosemennye mea kanu. Oia mau laau i beech, birch, lehu, walnut,ʻikeʻia i loko o ke au o ka Cretaceous, ola a hiki i keia la me kekahi hou. Land loaa ka mea mua flowering mea kanu - mua Magnolia, alaila, ku ae. Ma flowering ka mea, i ka lanakila i kā lākou pollen ua lawe ole wale makani, akā, i nā mea kolo. Hua kanu, e waiho ana i ka hua ma ka hua laha Via holoholona ai i ka hua. Penei, ka hua a me ka flowering kanu waikahe ka Honua holoʻokoʻa.

Loli ma ka flora i loko o ka Cretaceous wā i alakaʻi i ka muli o hou? Ueo o? Aaoa. Ma ka lewa Steel flit mua hahai, a lele nalo hopeʻeha ka hanai ana i ka manuʻapapane inu o ka pua. Ke kai hele mai domination foraminifera, make a me ka haihai iwi i haawi mai i ka inoa o nā mea a pau i kēia 'ā ina manawa. A me ka ia ma laila i nā mollusks, Amona. Ke iʻa aupuni Kīwala'ō ma lalo mano a me ka pokou iʻa. Nā holoholona o ka Mesozoic au hou - ma luna o nā mea a pau, na dinosaurs a me i kakahiaka nui mammals - maluhia "hoʻoneʻe" mai ka Canyon a hiki i ka Cretaceous. Akā, ma ka chalk kekahi mau make-hope lala o birdlike dinosaurs make mai, e like me archeopteryx. Akā, he mau manu - nā kūpuna o ke kālā no geese, kolea, Duck a me Loon.

Ke Mesozoic au (Canyon manawa ma ka nui), e like me ka ho film kaulana, ua iʻikeʻia e like me ke au o na dinosaurs. I mau, i ka noho aliʻi o ke kahiko dinosaurs malamaia ma ka chalk. Akā, ma ka hope i hala, Stegosaurus nalo, mai ke alo aku o ka honua, a me kona niche o Tyrannosaurus. Rich flora ka pilina i ka muli o hou ano o ka herbivorous dinosaurs: Triceratops, Iguanodon ankylosaur a me na mea e ae. Mākou ke olelo aku i loko o ka Cretaceous au dinosaur? Ueo 'ano ihu lua. A i keia manawa, i peʻe mai na kanaka nunui i loko o kā lākou mau burrows, ka mea ola a me ka wā e hiki mai luna o ka Honua - mammals. Mau holoholona, e like iole kākaʻikahi hiki i hoʻokahi mika ma ka lōʻihi, loa? Ueo he uuku egglayers, marsupials testaceous a uuku holoholona, he pāʻumi mai i 500 g. Akā, ma hope o lākou, i ka wā e hiki mai.
