Muddo dheer, dadku waxay saameyn ku yeesheen sawirka dinosaurs ee shaashadda, si T-rex loo tixgeliyo inuu yahay midka ugu sarreeya noocyada dinosauryada.Marka loo eego cilmi-baarista qadiimiga ah, T-rex runtii waxay u qalantaa inay istaagto xagga sare ee silsiladda cuntada.Dhererka T-rex qof weyn ayaa guud ahaan ka badan 10 mitir, xoogga qaniinyada cajiibka ah ayaa ku filan inuu jeexjeexo dhammaan xayawaanka kala badh.Labadan qodob oo keliya ayaa ku filan inay dadku caabudaan dinosaurkaan.Laakiin maaha nooca ugu xooggan ee dinosaurs-cunista, kan xoogga badana wuxuu noqon karaa Spinosaurus.
Marka la barbardhigo T-Rex, Spinosaurus waa mid aad u caan ah, taas oo aan ka go'in xaaladda dhabta ah ee qadiimiga ah.Marka la eego xaaladdii hore ee qadiimiga ah, cilmi-baarayaasha paleontologists waxay heli karaan macluumaad dheeraad ah oo ku saabsan Tyrannosaurus Rex oo ka soo jeeda fossils marka loo eego Spinosaurus, taas oo ka caawisa bini'aadamka inay sharaxdo sawirkeeda.Muuqaalka dhabta ah ee Spinosaurus weli lama go'aamin.Daraasadihii hore, cilmi-baarayaasha paleontologists waxay aqoonsadeen Spinosaurus inuu yahay dinosaur carnivorous ah oo weyn oo ku yaala bartamaha Cretaceous oo ku salaysan fossils Spinosaurus.Inta badan dareenka dadku waxay ka yimaadaan shaashadda filimka ama sawirro kala duwan oo dib loo soo celiyay.Laga soo bilaabo xogtan, waxaa la arki karaa in Spinosaurus uu la mid yahay xayawaannada kale ee daaweynta marka laga reebo lafdhabarta gaarka ah ee dhabarka.
Dhakhaatiirta Paleontologists waxay yiraahdeen aragtiyo cusub oo ku saabsan Spinosaurus
Baryonyx waxay ka tirsan tahay qoyska Spinosaurus marka la kala saaro.Dhakhaatiirta Paleontologists waxay ogaadeen jiritaanka miisaanka kalluunka ee caloosha Baryonyx fossil, waxayna soo jeediyeen in Baryonyx uu kalluumaysan karo.Laakiin taasi weli macnaheedu maaha in spinosaurs ay yihiin kuwo biyaha ku jira, sababtoo ah orso sidoo kale waxay jecel yihiin inay kalluumaystaan, laakiin maaha xayawaan badeed.
Later, cilmi-baarayaasha qaar ayaa soo jeediyay in ay isticmaalaan isotopes si ay u tijaabiyaan Spinosaurus, iyaga oo natiijada u qaadanaya mid ka mid ah caddaynta si loo xukumo in Spinosaurus uu yahay dinosaur biyood.Ka dib falanqaynta isotopic ee laf-dhabarka Spinosaurus, cilmi-baarayaashu waxay ogaadeen in qaybinta isotopic ay ku dhowdahay tan nolosha biyaha.
2008, Nizar Ibrahim, paleontologist at the University of Chicago, ayaa helay koox ka mid ah fossils Spinosaurus kuwaas oo aad uga duwan lafo la yaqaan oo ku yaal miinada Monaco.Qaybtan fossils ah ayaa la sameeyay xilliyadii dambe ee Cretaceous.Iyadoo loo marayo daraasadda laf-dhabarka Spinosaurus, kooxda Ibraahim waxay aaminsan tahay in Spinosaurus jirkeedu uu ka dheer yahay oo caato ah inta hadda la yaqaan, oo leh af la mid ah kan yaxaaska, lagana yaabo inuu koray flippers.Astaamahani waxay tilmaamayaan Spinosaurus inay yihiin kuwo biyood ama amphibians.
2018, Ibrahim iyo kooxdiisu waxay mar labaad ka heleen lafaha Spinosaurus ee Monaco.Markan waxay heleen laf dhabarta dabada Spinosaurus oo aad loo ilaaliyo iyo cidiyaha.Cilmi-baadhayaashu waxay si qoto dheer u falanqeeyeen Spinosaurus' laf dhabarta dabada waxayna ogaadeen in ay u badan tahay sida qayb ka mid ah jirka oo ay leeyihiin xayawaan badeed.Natiijooyinkani waxay bixiyaan caddayn dheeraad ah oo ah in Spinosaurus uusan ahayn gebi ahaanba xayawaan dhulka, laakiin dinosaur kaas oo ku noolaan kara biyaha.
ahaaSpinosaurusdinosaurka dhulka ama biyaha?
Markaa Spinosaurus ma dinosaurka dhulka, dinosaurka biyaha, ama dinosaurka amphibious?Natiijooyinka cilmi-baarista Ibraahim ee labadii sano ee la soo dhaafay ayaa ku filan si ay u muujiyaan in Spinosaurus uusan ahayn makhluuqa dhulka ee dareenka buuxa.Cilmi baaris, kooxdiisu waxay ogaatay in dabada Spinosaurus ay ku kortay laf dhabarta labada dhinac, iyo haddii dib loo dhiso, dabada waxay u ekaan doontaa shiraac.Intaa waxaa dheer, Spinosaurus 'dabada lafdhabarta waxay ahaayeen kuwo aad u jilicsan oo cabbirka jiifka ah, taas oo macnaheedu yahay in ay awoodeen inay daboolaan dabadooda xaglo waaweyn si ay u dhaliyaan awoodda dabaasha.Si kastaba ha ahaatee, su'aasha aqoonsiga dhabta ah ee Spinosaurus weli lama soo afjarin.Sababtoo ah ma jirto wax caddayn ah oo lagu taageerayo "Spinosaurus waa gebi ahaanba dinosaur biyood", sidaas darteed cilmi-baarayaal badan oo paleontologists ayaa hadda aaminsan in ay noqon karto xayawaan amfibious ah sida yaxaaska.
Isku soo wada duuboo, paleontologists ayaa dadaal weyn ku bixiyay daraasadda Spinosaurus, iyagoo muujinaya qarsoodiga Spinosaurus wax yar oo adduunka ah.Haddii aysan jirin aragtiyo iyo baaritaanno ka dhigaya garaadka dabiiciga ah ee bini'aadamka, waxaan aaminsanahay in dadka intooda badan ay weli u maleynayaan in Spinosaurus iyo Tyrannosaurus Rex ay yihiin xayawaannada dhulka.Waa maxay wajiga dhabta ah ee Spinosaurus?Aan sugno oo aragno!
