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 ichawira pamusoro penyika, zvichiita kuputika kukuru, zvakadai sokukanda guruva rakawanda mumhepo kuti riumbe Zhetianbiri Imba yeJecha uye Fog, yakatungamirira kumiswa kwechirimwa photosynthesis , Uye naizvozvo kuparara kwedinosaurs. 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 chekutsakatika kwedinosaurs kwave kusina zvishoma pane gumi nemaviri mamiriro ezvinhu, hupfumi hwakawanda kune zvinoshamisa uye zvinonakidza, "akadaro kudhumhana kwemeteorite," asi ndechimwe chazvo.Kuwedzera kune "meteorite kudhumhana", kutsakatika kwemadinosaurs pane pfungwa huru yekuona kune kushanduka kwemamiriro ekunze, kutanga kwakataurwa: Makore mamiriyoni 6500 apfuura, Panyika mamiriro okunze kamwe kamwe kuchinja tembiricha akadonha, zvichiita kuti yakaderera okisijeni mumhepo kuitira kuti dinosaurs aisagona kurarama.Zvakanziwo kuti dinosaurs vari chando-neropa, asi pasina bvudzi kana inodziya nhengo uye havagoni kuchinjika kuTembiricha yePasi akadonha, vakanga chando kufa.
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 kuti magineti munda wezvinhu zvipenyu, muPasi remagineti kuchinja, zvinogona kutungamirira kutsakatika.Zvinoita sokuti kutsakatika dinosaurs kungava chokuita kuchinja Earth remagineti. V. akati angiosperm poisoning. Kupera kweDinosaur era, Nyika gymnosperms zvishoma nezvishoma ichinyangarika, yakatsiviwa nenhamba yakawanda yeangiosperms, gymnosperms ine zvirimwa izvi hazvisi muchetura chimiro chehombe dinosaur chikafu chisingawanzoitiki, kudyiwa kwenhamba yakawanda yeangiosperms kwakatungamirira kuunganidzwa kwechepfu mumuviri Zvakanyanya, pakupedzisira mvura. Six, akati acid. 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.
