Nezvezvikonzero zvekutsakatika kwemadinosaurs, ichiri kuongororwa. Kwenguva yakareba, maonero ane chiremera, uye kupera kwema dinosaurs makore 6500 apfuura pamusoro pemeteorite yakakura. Maererano nokudzidza, paiva 7-10 km dhayamita asteroid achawira pamusoro penyika, zvichikonzera kuputika kukuru, zvakadai sokukanda guruva rakawanda mumhepo kuumba Zhetianbiri House of Sand uye Fog, yakatungamirira kune kumiswa kwechirimwa photosynthesis , Uye naizvozvo kuparara kwemadinosaurs.Asteroid impact theory yakakurumidza kuwana rubatsiro rwemasayendisiti akawanda. Muna 1991, muMexico's Yucatan Peninsula zvakaitika mukuwanikwa kwenguva yakareba meteorite impact craters, chokwadi ndehumwe humbowo hweiyi pfungwa. Nhasi, maonero aya anoratidzika kuva mhedziso.
Asi kunewo vanhu vazhinji nekuda kweiyo asteroid kukanganisa kune vanokahadzika, nekuti chokwadi ndechekuti: matatya, makarwe uye mamwe akawanda anonzwisisa zvakanyanya kutonhora kwemhuka vakaramba uye vakapona muCretaceous. Dzidziso iyi haigoni kutsanangura kuti sei madhinosaurs chete akafa. Kusvika iye zvino, masayendisiti akaisa mberi kwechikonzero chekuparara kwedinosaurs kwave kusina zvishoma pane gumi nemaviri ezviitiko, hupfumi hwakawanda kune zvinoshamisa uye zvinonakidza, "akadaro meteorite kudhumhana," asi ndeimwe yavo. "meteorite kudhumhana", kutsakatika kwemadinosaurs pane iyo huru yekuona pane zvinotevera:Kutanga, shanduko yemamiriro ekunze, akadaro. Mamirioni 6500 emakore apfuura, mamiriro ekunze ePasi anongoerekana achinja tembiricha yakadonha, zvichikonzera kuderera kweokisijeni mumhepo kuitira kuti madhinosaurs arege kurarama.Zvakanzi zvakare madhinaina ane ropa rinotonhora, asi asina bvudzi kana nhengo inodziya uye anogona. kwete kujairana neTembiricha yePasi yakadonha, yakaomeswa nechando kusvika pakufa kwe.
Chechipiri, marudzi, akati kurwa. Kupera kwedinosaur nguva, yakatanga kuonekwa mumhuka duku, mhuka idzi imbwa dzinodya dzinogona kudya mazai.Nekuda kwekushayikwa kwezvikara zviduku zvemhuka, zvakanyanya uye pakupedzisira zvinodya mazai.
Chechitatu, continental drift, akadaro. Geology Research inoratidza kuti kupona kwemadinosaurs pazera rePasi chete chikamu chenyika huru, kureva, "Pangea." Nekuda kwekuchinja kwepasi, kondinendi yakaitika muJurassic yechikamu chikuru uye kudonha, zvichitungamira kune zvakatipoteredza uye shanduko yemamiriro ekunze, uye nekudaro kupera kwemadinosaurs.
Chechina, shanduko mune geomagnetic yakati. Modern biology inoratidza kuti zvimwe zvipenyu uye magineti minda chokuita rufu.More anonzwisisa kune remagineti munda wezvinhu zvipenyu, muPasi remagineti kuchinja, zvinogona kutungamirira kutsakatika.Zvinoita sokuti kutsakatika dinosaurs kunogona chokuita kuchinja mu Magineti ePasi. V. akati angiosperm poisoning. Kupera kwenguva yedinosaur, iyo Earth gymnosperms inonyangarika zvishoma nezvishoma, yakatsiviwa nenhamba yakawanda yeangiosperms, magymnosperms ane zvidyarwa izvi hazvisi muchetura chimiro chekudya hombe dinosaur chikafu chisinganzwisisike, kudyiwa kwenhamba huru yeangiosperms inotungamira mukuunganidzwa kwehupfu mu. muviri Kunyanya, pakupedzisira chepfu.Six, akati acid mvura. Nguva yekupedzisira yeCretaceous inogona kunge yakange iri pasi pemvura yakasimba yeasidhi, ivhu, kusanganisira mune trace element strontium, inonyungudika dinosaurs kuburikidza nemvura yekunwa uye chikafu, zvakananga kana zvisina kunanga, strontium kudya, acute kana kusingaperi chepfu, mapoka ekupedzisira evakafa.
Zvikonzero zvekutsakatika kwemadinosaur pafungidziro yekuti zvataurwa pamusoro apa zvakanyanya kupfuura izvi. Asi izvi zvakataurwa pamusoro apa fungidziro munharaunda yesainzi ine vatsigiri vakawanda.Chokwadi, chimwe nechimwe chepamusoro, pane nzvimbo isina kukwana. Semuenzaniso, "kuchinja kwemamiriro ekunze" hakujekese zvikonzero zvekushanduka kwemamiriro ekunze. Mushure mekuongorora, mamwe madiki dinosaur muCoelurosauria, ane nguva yakakwana yekurwisa mhuka diki, saka "zvipenyu zvinonetsa kutaura" pane maburi. Muchimanjemanje geology, iyo "continental drift theory" pachayo ichiri fungidziro."Angiosperms poisoning" uye "acid rain" zvakafanana kushaikwa kwehumbowo hwakakwana. Nekuda kweizvozvo, chikonzero chaicho chekutsakatika kwemadinosaurs, havasati vazviongorora zvakare.
