Spinosaurus irashobora kuba dinosaur yo mu mazi?

Kuva kera, abantu bayobowe nishusho ya dinosaur kuri ecran, kuburyo T-rex ifatwa nkisonga ryubwoko bwinshi bwa dinosaur. Dukurikije ubushakashatsi bw'ibyataburuwe mu matongo, T-rex rwose yujuje ibisabwa kugira ngo ihagarare hejuru y'urunigi rw'ibiribwa. Uburebure bwa T-rex ikuze muri rusange burenga metero 10, kandi imbaraga zitangaje zo kuruma zirahagije gutanyagura inyamaswa zose mo kabiri. Izi ngingo zombi zonyine zirahagije kugirango abantu basenge iyi dinosaur. Ariko ntabwo arubwoko bukomeye bwa dinosaurs zinyamanswa, kandi izikomeye zishobora kuba Spinosaurus.

Ugereranije na T-Rex, Spinosaurus ntabwo izwi cyane, ikaba idashobora gutandukana nubuzima bwa kera. Urebye uko amateka ya kera yabayeho, abahanga mu bya paleontologue barashobora kubona amakuru menshi yerekeye Tyrannosaurus Rex mu bisigazwa by’ibinyabuzima kurusha Spinosaurus, ifasha abantu gusobanura ishusho yayo. Kugaragara kwukuri kwa Spinosaurus ntikiramenyekana. Mu bushakashatsi bwashize, abahanga mu bya paleontologue bagaragaje ko Spinosaurus ari dinosaur nini ya theropod carnivorous dinosaur hagati mu gihe cya Cretaceous ishingiye ku myanda yacukuwe ya Spinosaurus. Ibyinshi mubitekerezo byabantu biva kuri firime ya firime cyangwa amashusho atandukanye yagaruwe. Duhereye kuri aya makuru, birashobora kugaragara ko Spinosaurus isa nizindi nyamaswa zo mu bwoko bwa theropod usibye umugongo wihariye wa dorsal kumugongo.

Abahanga mu bya paleontologue bavuga ibitekerezo bishya kuri Spinosaurus
Baryonyx ni iyumuryango wa Spinosaurus mubyiciro. Abahanga mu bya paleontologue bavumbuye ko umunzani w’amafi uri mu gifu cy’ibimera bya Baryonyx, maze basaba ko Baryonyx ishobora kuroba. Ariko ibyo ntibisobanura ko spinosaurs iba mumazi, kuko idubu nayo ikunda kuroba, ariko ntabwo ari inyamaswa zo mumazi.
Nyuma, abashakashatsi bamwe basabye gukoresha isotopi kugirango bapime Spinosaurus, bafata ibisubizo nkimwe mubimenyetso byerekana niba Spinosaurus ari dinosaur yo mu mazi. Nyuma yisesengura rya isotopique ryibimera bya Spinosaurus, abashakashatsi basanze ikwirakwizwa rya isotopi ryegereye ubuzima bwamazi.

Mu mwaka wa 2008, Nizar Ibrahim, impuguke mu bya paleontologiya muri kaminuza ya Chicago, yavumbuye itsinda ry’ibimera bya Spinosaurus bitandukanye cyane n’ibimera bizwi ku birombe bya Monaco. Iki cyiciro cyibimera cyakozwe mugihe cyanyuma cya Cretaceous. Binyuze mu bushakashatsi bw’ibimera bya Spinosaurus, itsinda rya Ibrahim ryizera ko umubiri wa Spinosaurus ari muremure kandi woroshye kuruta uko bizwi ubu, ufite umunwa umeze nk’ingona, kandi ushobora kuba warakuze. Ibi bintu byerekana Spinosaurus kuba amazi cyangwa amphibian.
Muri 2018, Ibrahim nitsinda rye bongeye kubona ibisigazwa bya Spinosaurus muri Monaco. Kuriyi nshuro basanze Spinosaurus umurizo vertebra wabitswe neza. Abashakashatsi basesenguye vertebrae umurizo wa Spinosaurus mu buryo bwimbitse basanga bisa nkigice cyumubiri gifitwe n’ibinyabuzima byo mu mazi. Ubu bushakashatsi butanga ikindi kimenyetso cyerekana ko Spinosaurus itari ikiremwa cyo ku isi, ahubwo ko ari dinosaur ishobora gutura mu mazi.
YariSpinosaurusdinosaur yo ku isi cyangwa mu mazi?
None se Spinosaurus dinosaur yo ku isi, dinosaur yo mu mazi, cyangwa dinosaur amphibious? Ubushakashatsi bwakozwe na Ibrahim mu myaka ibiri ishize bwarahagije kwerekana ko Spinosaurus atari ikiremwa cyo ku isi muburyo bwuzuye. Binyuze mu bushakashatsi, itsinda rye ryasanze umurizo wa Spinosaurus wakuze mu mpande zombi, kandi aramutse yongeye kubakwa, umurizo wacyo wasaga n’ubwato. Byongeye kandi, umurizo wumugongo wa Spinosaurus wari woroshye cyane murwego rwa horizontal, bivuze ko bashoboye gufunga imirizo yabo kumpande nini kugirango babone imbaraga zo koga. Ariko, ikibazo cyimiterere nyayo ya Spinosaurus ntikirarangira. Kubera ko nta kimenyetso cyemeza “Spinosaurus ni dinosaur yo mu mazi rwose”, bityo abahanga mu bya paleontologue benshi bemeza ko ishobora kuba ikiremwa kidafite amoko nk'ingona.

Muri rusange, abahanga mu bya paleontologue bakoze ibishoboka byose mu bushakashatsi bwa Spinosaurus, bagaragaza ibanga rya Spinosaurus gahoro gahoro ku isi. Niba nta nyigisho nubuvumbuzi bihindura imyumvire yabantu, ndizera ko abantu benshi bagitekereza ko Spinosaurus na Tyrannosaurus Rex ari inyamanswa zo ku isi. Ni ubuhe buryo nyabwo bwa Spinosaurus? Reka dutegereze turebe!
