Dinozawusi yabayeho igihe kingana iki? Abahanga batanze igisubizo gitunguranye.

Dinosaurs ni bumwe mu bwoko bushimishije cyane mu mateka y'ubwihindurize ku binyabuzima ku isi. Twese tumenyereye cyane dinosaurs. Dinozawusi yasaga ite, dinosaurs yariye iki, ni gute dinosaurs yahigaga, ni ubuhe bwoko bwa dinosaur yabayemo, ndetse n'impamvu dinosaurs yazimye… Ndetse n'abantu basanzwe barashobora gusobanura ibibazo bisa na dinosaur muburyo bwumvikana kandi bwumvikana. Tumaze kumenya byinshi kuri dinosaurs, ariko hariho ikibazo kimwe abantu benshi bashobora kutumva cyangwa no gutekereza: Dinozawusi yabayeho igihe kingana iki?

Abahanga mu bya paleontologue bigeze kwizera ko impamvu dinosaurs yakuze cyane ari ukubera ko babayeho hagati yimyaka 100 kugeza 300. Byongeye kandi, nk'ingona, dinosaurs yari inyamaswa zikura zitagira imipaka, zikura buhoro buhoro kandi zikomeza mubuzima bwabo. Ariko ubu tumenye ko ataribyo. Diniosaurs nyinshi yakuze vuba cyane kandi apfa akiri muto.

· Nigute ushobora gucira urubanza ubuzima bwa dinosaurs?

Muri rusange, dinosaurs nini yabayeho igihe kirekire. Igihe cyo kubaho kwa dinosaurs cyagenwe no kwiga ibisigazwa by’ibinyabuzima. Mugukata amagufwa yatakaye ya dinosaur no kubara imirongo ikura, abahanga barashobora kumenya imyaka ya dinosaur hanyuma bagahanura ubuzima bwa dinosaur. Twese tuzi ko imyaka yigiti ishobora kugenwa no kureba impeta zayo. Kimwe n'ibiti, amagufwa ya dinosaur nayo akora "impeta zo gukura" buri mwaka. Buri mwaka igiti gikura, igiti cyacyo kizakura muruziga, cyitwa impeta yumwaka. Ni nako bimeze kumagufwa ya dinosaur. Abahanga barashobora kumenya imyaka ya dinosaurs biga "impeta yumwaka" yimyanda yamagufwa ya dinosaur.

Binyuze muri ubu buryo, abahanga mu bya paleontologue bavuga ko ubuzima bwa dinosaur ntoya ya Velociraptor bwari hafi imyaka 10 gusa; irya Triceratops ryari hafi imyaka 20; kandi ko umuyobozi wa dinosaur, Tyrannosaurus rex, yafashe imyaka 20 kugirango akure kandi ubusanzwe yapfuye hagati yimyaka 27 na 33. Carcharodontosaurus afite ubuzima bwo hagati yimyaka 39 na 53; binini binini byatsi-binini binini cyane, nka Brontosaurus na Diplodocus, bifata imyaka 30 kugeza 40 kugirango bakure, bityo babeho bafite imyaka igera kuri 70 kugeza 100.

Ubuzima bwa dinosaurs burasa nkaho butandukanye cyane nibitekerezo byacu. Nigute dinosaurs idasanzwe ishobora kugira ubuzima busanzwe? Inshuti zimwe zishobora kubaza, ni ibihe bintu bigira ingaruka kumibereho ya dinosaurs? Niki cyatumye dinosaurs ibaho imyaka mirongo gusa?

· Kuki dinosaurs itabayeho igihe kirekire?

Ikintu cya mbere kigira ingaruka kumibereho ya dinosaurs ni metabolism. Muri rusange, endotherms hamwe na metabolism yo hejuru ibaho igihe gito kuruta ectotherms hamwe na metabolism yo hasi. Abibonye, ​​inshuti barashobora kuvuga ko dinosaurs ari ibikururuka hasi, kandi ibikururuka hasi bigomba kuba inyamaswa zifite amaraso akonje kandi ziramba. Mubyukuri, abahanga basanze dinosaur nyinshi ari inyamaswa zifite amaraso ashyushye, bityo metabolisme yo hejuru ikagabanya ubuzima bwa dinosaur.

Icya kabiri, ibidukikije nabyo byagize ingaruka zica mubuzima bwa dinosaurs. Mubihe dinosaurs yabayeho, nubwo ibidukikije byari bikwiriye ko dinozawusi ibaho, byari bikabije ugereranije nisi muri iki gihe: umwuka wa ogisijeni uri mu kirere, okiside ya sulfure iri mu kirere n’amazi, hamwe n’imirasire ituruka isanzure yose yari itandukanye nuyu munsi. Ibidukikije nkibi, hamwe no guhiga ubugome no guhatana hagati ya dinosaur, byatumye dinosaur nyinshi zipfa mugihe gito.

Muri byose, ubuzima bwa dinosaurs burigihe ntabwo buri gihe nkuko buri wese abitekereza. Nigute ubuzima busanzwe busanzwe bwatumye dinosaurs iba umutware wigihe cya Mesozoic, yiganje kwisi imyaka igera kuri miriyoni 140? Ibi bisaba ubundi bushakashatsi bwakozwe na paleontologiste.
