"Mambo mhuno?".Ndiro zita rakapihwa kune ichangobva kuwanikwa hadrosaur ine zita resainzi Rhinorex condrupus.Yakatsvaga zvinomera zveLate Cretaceous makore makumi manomwe neshanu apfuura.
Kusiyana nemamwe mahadrosaur, Rhinorex yakanga isina bony kana nyama ine ganda pamusoro wayo.Pane kudaro, yaitamba mhino huru.Zvakare, yakawanikwa kwete mukati medombo rekunze semamwe mahadrosaur asi paBrigham Young University pasherufu mukamuri rekuseri.
Kwemakumi emakore, vavhimi vezvinyorwa zvemadhinaso vaiita mabasa avo nepiki nefoshoro uye dzimwe nguva dynamite.Vaitsemura nokuparadza matani ematombo muzhizha rimwe nerimwe, vachitsvaka mapfupa.Marabhoritari epaYunivhesiti uye mamuseum enhoroondo akazadzwa nesarasara kana akazara skeletons edhinosaur.Chikamu chikuru chezvisaririra, zvisinei, zvinoramba zviri mumakrete uye plaster inokandwa inoraswa mumabhini ekuchengetera.Havana kupihwa mukana wekutaura nyaya dzavo.
Mamiriro ezvinhu aya achinja.Dzimwe nyanzvi dze paleontologist dzinotsanangura sainzi yedhinoso seyave nekuvandudzwa kwechipiri.Zvavanoreva ndezvekuti nzira nyowani dziri kutorwa kuti uwane nzwisiso yakadzama yehupenyu uye nguva dzemadinosaur.
Imwe yeaya maitiro matsva ndeyekungotarisa izvo zvakatowanikwa, sezvakaita nyaya yeRhinorex.
Muma1990, zvisaririra zveRhinorex zvakaiswa paBrigham Young University.Panguva iyoyo, nyanzvi dze paleontologist dzaitarisa pane zveganda zvakawanikwa pahadrosaur trunk bone, zvichisiya nguva shoma yemadehenya akaumbwa achiri mumatombo.Zvadaro, vaviri vanoongorora postdoctoral vakasarudza kutarisa dehenya redhinaso.Makore maviri gare gare, Rhinorex yakawanikwa.Nyanzvi dzepaleontologist dzakanga dzichibudisa chiedza chitsva pabasa radzo.
Rhinorex yakatanga kucherwa kubva kunzvimbo yeUtah inonzi Neslen saiti.Nyanzvi dzeGeologist dzaive nemufananidzo wakajeka wenzvimbo yeNeslen yekare kare.Yakanga iri nzvimbo inogarwa nehosha dzemvura, nzvimbo yakaderera ine mvura yakachena nemunyu yakasangana pedyo nemhenderekedzo yegungwa rekare.Asi mukati menyika, makiromita 200 kubva kure, nzvimbo yacho yakanga yakasiyana zvikuru.Mamwe mahadrosaur, rudzi rwecrested, akacherwa mukati menyika.Nekuti vekare vepalenontologists havana kuongorora yakazara Neslen skeleton, vakafunga kuti zvakare yaive crested hadrosaur.Nekuda kwefungidziro iyoyo, mhedziso yakaitwa yekuti ese ma crested hadrosaur aikwanisa kushandisa zviwanikwa zvemukati menyika uye estuarine zvakaenzana.Yakanga isiri iyo palenotologists vakaiongorora zvakare kuti yaive Rhinorex.
Kufanana nechidimbu chepuzzle chinowira munzvimbo, kuwana kuti Rhinorex yaive mhando nyowani yeLate Cretaceous life.Kuwana "King Nose" kwakaratidza kuti mhando dzakasiyana dzehadrosaur dzakachinjika uye dzakashanduka kuti dzizadze dzakasiyana niches ecological.
Nekungotarisa zvakanyanya pazvisaririra mumabhini ekuchengetera ane guruva, paleontologists vari kuwana matavi matsva emuti wedhinaso weupenyu.
