"Mhuno yeMambo?". Ndiro zita rakapihwa hadrosaur ichangobva kuwanikwa ine zita resainzi rekuti Rhinorex condrupus. Yakatsvaga zvinomera zveLate Cretaceous makore angangoita mamiriyoni makumi manomwe nemashanu apfuura.
Kusiyana nedzimwe hadrosaurs, Rhinorex yakanga isina mapfupa kana nyama pamusoro wayo. Asi, yakanga ine mhino hombe. Zvakare, yakawanikwa kwete munzvimbo ine matombo semamwe hadrosaurs asi paBrigham Young University pasherufu mukamuri rekumashure.
Kwemakumi emakore, vavhimi vezvisaririra zvemadinosaur vaiita mabasa avo nepick nefoshoro uye dzimwe nguva dynamite. Vaicheka nekuputika matani ematombo zhizha rega rega, vachitsvaga mapfupa. Marabhoritari emayunivhesiti nemamiziyamu enhoroondo yezvisikwa akazadzwa nemarara ezvisaririra zvemadinosaur asina kukwana kana akazara. Zvisinei, chikamu chikuru chezvisaririra zvemadinosaur chinosara mumabhokisi uye plaster yakakandwa mumabhini ekuchengetera zvinhu. Havana kupihwa mukana wekutaura nyaya dzavo.
Mamiriro ezvinhu aya achinja izvozvi. Vamwe vaongorori venhoroondo dzemadinosaur vanotsanangura sainzi yemadinosaur seyava kudzoka patsva kwechipiri. Zvavanoreva ndezvekuti nzira itsva dziri kutorwa kuti vawane ruzivo rwakadzama nezvehupenyu nenguva yemadinosaur.
Imwe yenzira itsva idzi ndeyekungotarisa zvakatowanikwa, sezvakaitika kuRhinorex.
Mumakore ekuma1990, zvisaririra zveRhinorex zvakachengetwa paBrigham Young University. Panguva iyoyo, nyanzvi dzepaleontologists dzakatarisa paganda rakawanikwa pamapfupa ehunde yehadrosaur, zvichisiya nguva shoma yedehenya remafossil richiri mumatombo. Zvadaro, vaongorori vaviri vepostdoctoral vakasarudza kutarisa dehenya redinosaur. Makore maviri gare gare, Rhinorex yakawanikwa. Nyanzvi dzepaleontologists dzakanga dzichijekesa basa ravo.
Rhinorex yakambocherwa kubva kunzvimbo yeUtah inonzi Neslen. Nyanzvi dzezve geology dzakaona zvakajeka nzvimbo yeNeslen yekare kare. Yaive nzvimbo yekugara yegungwa, nzvimbo ine madhaka umo mvura yakachena nemunyu zvaisangana pedyo negungwa rekare. Asi mukati megungwa, makiromita mazana maviri kubva ipapo, nzvimbo yacho yakanga yakasiyana zvikuru. Mamwe ma hadrosaurs, rudzi rwe crested, akacherwa mukati megungwa. Nekuti nyanzvi dzekare dzepalenontologists hadzina kuongorora skeleton yese yeNeslen, vakafunga kuti yaive crested hadrosaur. Nekuda kwefungidziro iyoyo, mhedziso yakawanikwa yekuti ma hadrosaurs ese crested aigona kushandisa zviwanikwa zvemukati ne zvegungwa zvakaenzana. Zvakatora nguva kuti nyanzvi dzepalenotologists dziongororezve kuti yaive Rhinorex.
Kufanana nechidimbu chepuzzle chiri kuitika panzvimbo yacho, kuwana kuti Rhinorex yaive mhando itsva yehupenyu hweLate Cretaceous. Kuwana "King Mhuno" kwakaratidza kuti mhando dzakasiyana dzehadrosaurs dzakachinja-chinja kuti dzizadze nzvimbo dzakasiyana dzezvakatipoteredza.
Nekungotarisa zvakanyanya mafossil ari mumabhini ekuchengetera ane guruva, nyanzvi dzepaleontologists dziri kuwana matavi matsva emuti wehupenyu wedinosaur.
