Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Vatsvakurudzi vaviri, Chris Bennett (1996) naDavid Peters (2000), vakawana kuti pterosaurs aiva protorosaurs kana kuti aiva noukama hwepedyo nawo. Peters akashandisa unyanzvi hunonzi DGS, hunosanganisira kushandisa zvinhu zvomushandisirwo wemifananidzo yesoftware yokugadzira mifananidzo pamifananidzo yezvicherwa zvepterosaur. Bennett akawanazve pterosaurs sehama dzepedyo dzeprotorosaurs mushure mekubvisa hunhu hwemakumbo ekumashure kubva mukuongorora kwake, mukuyedza kuyedza pfungwa yekuti hunhu uhwu mhedzisiro yekushanduka-shanduka pakati pe pterosaurs nema dinosaurs. Zvisinei, kuongorora kwakazoitwa naDave Hone naMichael Benton (2007) hakuna kukwanisa kudzokorora zvakabuda pakutsvakurudza uku. Hone naBenton vakawana kuti pterosaurs yakanga yakafanana zvikuru nemadhinosaurs kunyange pasina mavara emakumbo omashure. Vakatsoropodzawo zvidzidzo zvakapfuura zvaDavid Peters, vachimutsa mibvunzo pamusoro pokuti mhedziso dzakasvika pasina kuwana uchapupu hwepakutanga, kureva kuti, zvisaririra zvepterosaur, zvinogona kunzi zvine simba rakaenzana nemhedziso dzakavakirwa pakududzira kwakananga. Hone naBenton vakagumisa kuti, kunyange zvazvo pterosauromorphs dzapakuvamba zvikuru dzichidikanwa kujekesa ukama hwadzo, pterosaurs dzakanakisisa dzinorangarirwa archosaurs, uye zvikurukuru ornithodirans, dzakapiwa uchapupu hwazvino. Mukuongorora kwaHone naBenton, pterosaurs ingave iri boka rehanzvadzi reScleromochlus kana kuwira pakati payo neLagosuchus pamuti wemhuri yeornithodiran. Sterling Nesbitt (2011) akawana rutsigiro rwakasimba rwechikamu chinoumbwa neScleromochlus uye pterosaurs. Zvidzidzo zvitsva zvikuru pamusoro pechimiro chendangariro chetsoka dzapashure dzepterosaur zvinoratidzika kuva zvinoruramisa kubatana neScleromochlus. Kufanana neiyi archosaur, mitsara yemapterosaur yomuzasi ine makumbo apashure eplantigrade anoratidza kugadziridzwa nokuda kwokuiswa munyu.  Mubvunzo: Chii chiri ukama pakati pepterosaurs mukuwirirana nokuongorora kwaHone naBenton?
