Sei dinosaurs: fembera vezvesayenzi

Dinosaurs havasi gumi yokuva nyaya kuteerera kwete chete vanhuwo wokutanga, asi nyanzvi. Vari kuedza kudzidza pamusoro izvi chakavanzika zvisikwa zvose sei panyika akaita zvokuzviuraya kuti nei dinosaurs vakava yakatotsakatika mhando iyi. Kunyange zvazvo riri rokupedzisira nyaya hanya masayendisiti vari kukura pamwe roga gore vakawanda shanduro itsva.

Dinosaurs vakava yakatotsakatika kubva extraterrestrial kubvuta

Kwete, zvachose haritauri chokuita nechisimba vatorwa. Panyaya iyi, chikuru chikonzero zvachose kutsakatika pakati dinosaurs anoratidza zvinoitwa kwemiviri yokudenga. Zvinofungidzirwa kuti dinosaurs akafa nokuda mumwe zvinhu zvinotevera: kuwa hombe asteroid, vakawanda "bombardment" asteroids panyika, panyika kudhumhana pamwe kometi uye kuvandudzika nemwaranzi yakafanira supernova kuputika kana zvimwe zvinhu saizvozvo. hunhu.

Zvidzidzo Geological vanogara akasimbisa chokwadi kuti pamusoro paNyika rave kakawanda pasi dzakasiyana kukura asteroids kuwa. In kuisa mberi shanduro nei dinosaurs vakava yakatotsakatika, vateveri dzidziso "asteroid bombardment" anoratidza anofungidzirwa musi kufanana wokuwira kwavo uye vakawanda kutsakatika dinosaurs. Zvinokosha kucherechedza kuti dzidziso iyi, masayendisiti ari chete zvishoma anotsigirwa: yefizikisi vanoti chakanga zvakakwana edinokratnogo kuwa, dzichishandisa zvidzidzo Crater Chicxulub uye muchadenga Masvomhu enyika colliding nevamwe miviri yokudenga. Ivo vanopikiswa Nyanzvi paleontologists, nharo kuti kuchinja zvinoshamisa muna Fauna of panyika anogona kuitika chete somugumisiro inodzokororwa donhwe. Kuti sezvo zvingaita, muchiitiko ichi hazvina basa izvo dinosaurs multiple edinokratnogo kana asteroid. The chikuru ndechokuti somugumisiro akawanda iri mhando yaparadzwa anenge edinomomentno.

Isa mberi yakasiyana shanduro idzodzo sezvo chikuru chinokonzera rufu kunongedzera kuwedzera muna nemwaranzi mumatunhu. chiitiko ichi, masayendisiti vanoti, zvakakonzera chokwadi kuti Pasi akatanga kugamuchira zvishoma chezuva nemhaka mumuviri uye zvemakemikari pezvakaitwa kwakaitika pasi muchadenga. Somugumisiro, paiva kutonhora kwakapararira kuti anokanganisa kukanganisa ine utsinye mhuka. Uyezve, uwandu nemwaranzi kuti hwapinda kuburikidza mumhepo akaturikidzana, uyewo aiva mafungiro zvipenyu dzinotsanagura kubereka, achidzikisa kwavari chinenge kusvikira razero.

Akauya dzidziso nei dinosaurs vakava yakatotsakatika, vari, saka kutaura, mumwe ane mativi hunhu. Kazhinji, vose "extraterrestrial" pfungwa akavaka pundits vaiva vamiririri mumwe izvi tsvakurudzo nzvimbo. Kana izvi hazvirevi kufungawo zvimwe zvikonzero zvakazara buritsa kutsakatika kwemarudzi.

Kana isu kuna sayenzi rimwe, zvinokwanisika kusunda mumwe uwandu nezvemutauro sei dinosaurs vakava yakatotsakatika kubva. Wokutanga izvi ndiyo dzidziso yose kuchinja Panyika. Warinozokwidzwa kufungawo zvinhu zvinoverengeka, kureva, sangano kwamahwendefa, kuchinja wegungwa pasi, sezvo migumisiro maviri okutanga - akasvetuka kupisa uye kuchinja Zvinoumba kasvisto uye mhepo.

The shanduro nei dinosaurs vakava yakatotsakatika wechipiri, ndiye akachinja nemiti nyika, inobva kufamba pamusoro tectonic kwamahwendefa. Somugumisiro, mashoko zvikara vaigona zvinobudirira kuparadza vaduku dinosaurs uye mazai kuisa, uye pakudaro waidzora kubereka zvipenyu izvi nenzira kudzikira.

Ndivo mukuru dzidziso kuti vanoedza kutsanangura nei dinosaurs vakava nokutsakatika. Sezvaunogona kuona, mumwe nomumwe wavo rinoshandisa munhu chinhu, uye vamwe anopiwa kukosha. Ndokusaka zvichikosha kuti nokubatanidza nhengo hypotheses vari kwakaitika zvinhu uchapupu uye, kunobva chete kuratidzwa.
