Mō ngā take i ngaro ai ngā tainasoa, kei te rangahauhia tonutia. Mō te wā roa, ko te tirohanga tino mana, me te ngaronga o ngā tainasoa 6500 tau ki muri mō tētahi meteorite nui. E ai ki te rangahau, i taka tētahi asteroid 7-10 km te whānui ki te mata o te whenua, ka puta he pahūtanga nui, pērā i te maka i te nui o te puehu ki te hau hei hanga i te Whare Oneone me te Kohu o Zhetianbiri, i arahina ai ki te whakamutua o te photosynthesis o ngā tipu, ā, nō reira i ngaro ai ngā tainasoa. I tere te tautoko a te maha o ngā kaipūtaiao i te ariā pānga asteroid. I te tau 1991, i te Yucatan Peninsula o Mexico i kitea ai he rua pānga meteorite mō te wā roa, ko te meka he taunakitanga anō mō tēnei tirohanga. I ēnei rā, te āhua nei kua waiho tēnei tirohanga hei whakatau.
Engari he tokomaha hoki ngā tāngata e whakahē ana mō te pānga o tētahi asteroid pēnei, nā te mea ko te mea pono: ko ngā poroka, ngā korokotairo me te tini ke atu he tino pāngia e te pāmahana o ngā kararehe kua ātete, ā, kua ora i te wā Cretaceous. Kāore e taea e tēnei ariā te whakamārama he aha i mate ai ngā tainasoa anake. Tae noa ki tēnei wā, kua whakatakotohia e ngā kaipūtaiao mō te take o te ngaronga o ngā tainasoa he tekau mā rua ngā āhuatanga, he nui ake te taonga ki te whakaari me te whakahihiri, "e ai ki te tukinga meteorite," engari ko tētahi o aua mea. Haunga te "tukinga meteorite", ko te ngaronga o ngā tainasoa i runga i te tirohanga matua ko ēnei e whai ake nei: Tuatahi, te huringa āhuarangi, e ai ki te kōrero. 6500 miriona tau ki muri, ka huri ohorere te āhuarangi o te Ao i te hekenga o te pāmahana, ka heke te hāora i roto i te hau, ā, kāore e taea e ngā tainasoa te ora. I whakaarohia hoki he toto makariri ngā tainasoa, engari kāore he huruhuru, he okana mahana rānei, ā, kāore e taea te urutau ki te hekenga o te pāmahana o te Ao, ka tio ki te mate.
Tuarua, ko te momo, e ai ki te pakanga. I te mutunga o te wā o ngā tainasoa, i puta tuatahi mai i roto i ngā kararehe iti, ko ēnei kararehe he kiore kaipahua ka kai pea i ngā hua. Nā te korenga o ngā kararehe iti kaipahua, ka nui haere te kai i ngā hua, ā, ka mutu, ka pau katoa.
Tuatoru, ko te nekenekehanga whenua. E whakaatu ana ngā rangahau matawhenua ko te oranga tonutanga o ngā tainasoa i te wā o te Ao he wāhanga noa iho o te tuawhenua, arā, ko "Pangea." Nā ngā panonitanga o te kirinuku o te whenua, i puta te whenua i te wā Jurassic o te wehenga nui me te nekenekehanga, ka arahi ki te huringa taiao me te āhuarangi, ā, nō reira ka ngaro ngā tainasoa.
Tuawhā, ko ngā panonitanga o te geomagnetic i kīia. E whakaatu ana te koiora hou ko ētahi mara koiora me te aukume e pā ana ki te matenga. He nui ake te aro ki te mara aukume o te koiora, i roto i ngā panonitanga o te mara aukume o te Ao, ka arahi pea ki te ngaronga. Nō reira, te āhua nei ko te ngaronga o ngā tainasoa he hononga pea ki ngā panonitanga o te mara aukume o te Ao. I kīia te paihana angiosperm. I te mutunga o te wā tainasoa, ka ngaro haere ngā gymnosperm o te Ao, ka whakakapia e te maha o ngā angiosperm, kei roto i ngā gymnosperm ēnei tipu kāore i roto i te āhua paitini o te dinosaur nui he kai rerekē, ko te kai o te maha o ngā angiosperm i arahi ki te kohikohinga o ngā paitini i roto i te tinana. He nui rawa, ko te paihana whakamutunga. Ono, i kīia te ua waikawa. Ko te wā Cretaceous mutunga pea i raro i te ua waikawa kaha, oneone, tae atu ki te huānga iti o te strontium, ka rewa ngā tainasoa mā te wai inu me te kai, tika, kore tika rānei, te kai strontium, te paihana whakapeka, te paihana mau tonu rānei, ko ngā rōpū whakamutunga o te hunga mate.
Ko ngā take mō te ngaromanga o ngā tainasoa kei runga i te whakapae he nui ake ngā mea kua whakahuatia i runga ake nei i ēnei. Engari he nui ake ngā kaitautoko o ēnei whakapae kua whakahuatia i roto i te hapori pūtaiao. Ko te tikanga, he wāhi tino koretake ia o ngā mea kua whakahuatia i runga ake nei. Hei tauira, kāore te "huringa āhuarangi" e whakamārama i ngā take o te huringa āhuarangi. Whai muri i te tirotiro, ko ētahi tainasoa iti i roto i te Coelurosauria, me te nui o te wā ki ngā kararehe iti, nā reira "he uaua ki ngā momo te kī" he arai. I roto i te matawhenua hou, ko te "ariā nekeneke whenua" tonu he whakapae. "Ko te paihana o ngā angiosperms" me te "ua waikawa" he rite tonu te kore o ngā taunakitanga. Nō reira, ko te tino take o te ngaromanga o ngā tainasoa, kāore anō kia tūhuratia atu.
