Dinosaur nini cyane yageze ite i Burayi? Ibisigazwa bishya biratanga igisubizo

Dinosaur yari imeze ite? Dinosaur yari dinosaur nini yari ibayeho mu mpera z’igihe cya Jurassic, hashize hafi imyaka miliyoni 150.

Ibisigazwa byabonetse ni ibihe? Abashakashatsi babonye amagufa 14 yo mu murizo wa Diplodocus, hamwe n’andi magufa mato yafashaga mu gushyigikira imitsi n’imiyoboro y’amaraso yo mu murizo. Nubwo igice kinini cy’umubiri w’iyo dinosaur kitaraboneka, abashakashatsi basanze ayo magufa afite ibimenyetso bihuye n’ibiranga Diplodocus, birimo imyobo minini ijyanye n’aho udufuka tw’umwuka twari kuba turi ndetse n’imirongo yimbitse ku magufa yo munsi y’umurizo.

Yageze ite mu Burayi? Iki ni kimwe mu bibazo by’ingenzi ubu buvumbuzi bwazamuye. Abashakashatsi bavuga ko mu gihe Diplodocus yabagaho, umugabane wa Pangaea wari umaze gutangira gucikamo ibice, ariko inyanja ya Atlantique yari itaraba nini nk’uko iri muri iki gihe. Bavuga ko bishoboka ko hari inzira z’ubutaka zashoboraga gufasha inyamaswa kwimuka hagati y’uturere twa Amerika ya Ruguru n’u Burayi.

Ubu buvumbuzi buhindura iki ku byo abahanga bari basanzwe bazi? Mbere y’ubu buvumbuzi, ibisigazwa bya Diplodocus byo mu gihe cya Late Jurassic byari bizwi cyane muri Morrison Formation yo mu burengerazuba bwa Leta Zunze Ubumwe za Amerika.

Abashakashatsi bavuga ko hakenewe ibisigazwa byinshi kugira ngo hamenyekane neza ubwoko bwa Diplodocus bwabaga mu Burayi, ndetse no kumenya niba bwari ubwoko busanzwe buzwi muri Amerika ya Ruguru cyangwa niba hari ubundi bwoko butari buzwi mbere.
