Pfupisa nyaya yacho:  Brontosaurus yakadzoka zvine simba pashure pokunge yatapwa nenzanga yesayenzi. Dinosaur ine mutsipa murefu yakanga iri imwe yemhuka dzakakura zvikurusa dzati dzambofamba Pasi nenhaka yayo inobata fungidziro dzavana munyika yose. Asi pasinei zvapo ne'shumba yemheni' yakadzika midzi mutsika dzakakurumbira, kweanopfuura zana ramakore masayendisiti aidavira kuti iyi dinosaur ine mukurumbira wakashata haina kutongovapo. Dinosaur huru nezita rayo rinokwezva - rinoreva kuti'mhashu inotinhira' - rakafadza zvizvarwa zvevaduku. Asi kubvira muna 1903, nyanzvi dzave dzichitenda kuti chisikwa chacho pakutanga chakapiwa zita risiri iro. Mufananidzo uyu ndiBrontosaurus sezvinoratidzwa nevatsvakurudzi nhasi - ine musoro wakaita seweDiplodocus. Vatsvakurudzi vacho vakatarira zvinhu 477 zvomuviri zvaiva mudinosaurs 81 dzaiwanika mumamiziyamu muEurope nomuUnited States. Panzvimbo penzira yechinyakare yokuratidza kuti rudzi rumwe norumwe rwakafanana zvakadini nerumwe, vakashandisa 'bumbiro remitemo rinotorwa mumuenzaniso.' Izvi zvaireva kuti vaigona kuongorora mhuka imwe neimwe, pasinei zvapo nemarudzi ayo, uye zvakavabvumira kutarisa misiyano mukati memarudzi ose, pamwe chete pakati pemarudzi akasiyana. Chimiro chikuru chomuti wacho chakabvumirana nezvakanga zvambotaurwa nedzimwe nyanzvi dzezvinhu zvipenyu kare, asi zvisaririra zvakatanga kunzi Brontosaurus zvairatidzika zvakasiyana nemarudzi maviri eApatosaurus. Misiyano mizhinjisa yakanga iri muzvinhu zviduku zvomuviri, asi chimiro chimwe chakasiana chakanga chiri chokuti Apatosaurus ine mutsipa wakafara kupfuura Brontosaurus. Kubvira muna 1903, nyanzvi dzave dzichitaura kuti chisikwa chacho pakutanga chakapiwa zita risiri iro. Panzvimbo pokuva worudzi, kana kuti "mhuri" yemarudzi Brontosaurus, vakati chaizvoizvo yaifanira kuva yakarongwa se"Apatosaurus". Zvino nzvero itsva yakaratidza kuti, pashure pezvose, yakasiana zvakakwana neApatosaurus kuti iwane zita rayo amene rechirudzi. Masayendisiti anobva kuUK nePortugal akapa uchapupu hwokumutsidzira Brontosaurus mufundo yemapeji anenge 300 akabudiswa mumagazini yePeerJ. 'Kusiyana kwatakawana pakati peBrontosaurus neApatosaurus kwakanga kwakawanda sezvakaita...
Kubvira muna 1903, masayendisiti ave achiti Brontosaurus haipo. Vakati rudzi rune mukurumbira runofanira kurongwa seApatosaurus. Kudzidza kutsva kwakaverenga misiyano iri pakati pemhuri dzeDiplodocid. Brontosaurus yakanga ine mutsipa mutete uye mapfupa akasiyana zvishoma.
