Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Mashoko: Chimwe chezvinhu zvokutanga zvakanyorwa pamusoro peIguanodon chaiva chokuti yakanga ine mazino ezvipembenene zvinodya zvinomera, kunyange zvazvo pasina nguva dzose kwave kune kubvumirana pamusoro pokuti yaidya sei. Sezvakataurwa naMantell, zvisaririra zvaakanga achishanda nazvo zvakanga zvisina kufanana nechinokambaira chipi nechipi chemazuva ano, zvikurukuru muchimiro chisina mazino, chakaita sechinhu chinokambaira chomutsipa wepasi, icho akawana chiri chakanakisisa mukuenzanisa neicho chomuswe une minwe miviri uye muswe wakatsakatika wepasi Mylodon. Akataurawo kuti Iguanodon yaiva norurimi runobata rwaigona kushandiswa kuunganidza zvokudya, kufanana negirafu. Zvimwe zvisaririra zvakazara zvakaratidza kuti uku kwaiva kukanganisa; somuenzaniso, mapfupa ehyoid aitsigira rurimi akavakwa zvakasimba, zvichiratidza kuti rurimi rune tsandanyama, rusingabatiki rwaishandiswa kufambisa zvokudya mumuromo. Pfungwa yerurimi rwegirafu yakapiwawo Dollo nenzira isiri iyo kupfurikidza nomuromo wakaputsika. Ganda romusoro rakanga rakagadzirwa nenzira yakadaro yokuti sezvo rakapfupika, mapfupa anotsigira mazino mumuromo wokumusoro aizokotama. Izvi zvaizoita kuti mazino epamusoro emhino dzeshaya dzokumusoro apwanye mazino epamusoro emhino dzeshaya dzokumusoro, achikuya chinhu chipi nechipi chinenge chabatwa pakati nepakati ndokuita chiito chakafanana nokuruma kunoitwa nemhuka dzinoyamwisa. Nemhaka yokuti mazino aigara achitsiviwa, mhuka yacho ingadai yakashandisa nzira iyi kwoupenyu hwayo hwose, uye yaigona kudya zvinhu zvakasimba zvinomera. Uyezve, mativi epamberi emihino yemhuka yacho akanga asina mazino uye aiva nemakumbo ane mapfupa, ari kumusoro uye ari pasi, zvichiita kuti pave nemucheto wakanga wakavharwa uye wakareba nechimwe chinhu chinonzi keratinous chichiita kuti pave nemuromo wokudimburira nawo matavi nemakwenzi. Kuunganidza kwayo zvokudya kwaizova kwakabetserwa nomunwe wayo muduku unochinjika, uyo waigona kuva wakashandiswa kubata zvinhu, kusiyana nemimwe minwe.  Mubvunzo: Ndiani akanga achicherechedza nezvezvisikwa zvakaita sezvipembenene?
