Soo koob maqaalka:  Waxay u badan tahay inay tahay mid ka mid ah dinosaur-yada ugu caansan ee la helay sababtoo ah xariiqda cajiibka ah ee taarikada gaashaaman ee dhabarka. Hada, cilmi baaris cusub ayaa cadeysay in labka iyo dumarka stegosaurus ay lahaayeen xuubyo kala duwan oo kasoo baxa dhabarkooda. Waxay soo jeedinaysaa suurtagalnimada in Diinoosaaradu ay isticmaaleen lafahooda waaweyn, oo gaadhayey ilaa 2.5 feet, si ay isugu soo jiitaan. Cilmi-baadhayaashu waxay ogaadeen in Stegosaurus labka ah (kor) uu lahaa taarikada gaashaaman oo qaab ka duwan dumarka (hoos) Palaeontologists ayaa sheegaya in Stegosaurus labka ah ay u isticmaali karaan inay ku muujiyaan awoodooda si la mid ah sida paws ay maanta sameeyaan. Cilmi baaristu waxay sidoo kale gacan ka geysatay in laga jawaabo dhibaato ku hadhay aqoonyahanada qadiimiga ah tobanaan sano. Lamaane u eg Turkey-size <unk> jajabyada tuugada <unk> loo yaqaan Romeo iyo Juliet ayaa laga helay midba midka kale dhinaciisa dhagax 75 milyan oo sano jir ah badhtamihii 90-meeyadii, laakiin waxay ku qaadatay ilaa hadda khubarada si loo go'aamiyo jinsiga 'jaceylka'. Hada, cilmi baarayaashu waxay aaminsanyihiin in ay heleen dariiq ay ku kala saaraan burushka dinosaur-yada ragga iyo dumarka. Waxay sheegeen in farqiga u dhaxeeya labka iyo dhedigga uu ku jiro lafaha ku dhow salka dabada. Khubarada cilmiga duugta ah ee jaamacadda Alberta waxay baareen laba burburin oo laga helay Mongolia, kuwaas oo markii ugu horreysay lagu sharraxay 2001. Mid waa qalfoof dhamaystiran, halka kan kalena uu ka maqan yahay bartamaha iyo dhamaadka dabada. cilmi baarayaashu waxay eegeen caddeyn aan toos ahayn oo ah qaab dhismeedka galmada ee galmada, taas oo maanta ka muuqata shimbiraha. Tusaalooyinka waxaa ka mid ah baalasha digaaga, dhabanada dheer ee digaagga ama baalasha dheer ee shimbiraha janada qaarkood, kuwaas oo loo isticmaalo soo jiidashada iyo kaftanka. caado ahaana way ka weyn yihiin dumarka, kuwaasoo doorbidaya. Kooxda ayaa soo jeedisay in sida shimbiraha oo kale, dinosaur-yada yar yar ee baalal leh sida oviraptors ay u isticmaali jireen baalal dhaadheer oo ku yaal dabadooda si ay u soo jiitaan lammaanaha, halkii ay u duuli lahaayeen. Stegosaurus-yada qaar ayaa laga helay kuwo leh shabaqyo balaadhan halka kuwo kalena ay lahaayeen shabaqyo dhaadheer oo leh caarado fiiqan oo ahaa 45 boqolkiiba...
Stegosaurus ayaa laga helay laba nooc oo kala duwan oo ka mid ah dhabarka dhabarka - oo ah dhagxaanta ballaaran ee ballaaran iyo dhagxaanta dhaadheer ee dhaadheer ee yaryar. Khubarada waxay muddo dheer aaminsanaayeen in ay ka tirsan yihiin noocyo kala duwan oo Stegosaurus ah. Cilmi baadhis cusub ayaa lagu ogaaday in qaababka kala duwan ay kala garan karaan labka iyo dumarka. Khubarada cilmiga dhulka ayaa sheegaya in looxyada loo isticmaali karo in lagu soo jiito lammaane.
