Dhinosaurs yakabuda kubva kumadzitateguru avo archosaurs mukati mepakati kusvika kunopera Triassic nguva, makore anenge mamirioni makumi maviri mushure mekutsakatika kwePermian<unk>Triassic chiitiko chakatsvaira fungidziro ye95% yehupenyu hwese paPasi. Radiometric kufambidzana kwekuumbwa kwedombo kwaive nemafosili kubva kune yekutanga dinosaur genus Eoraptor pa 231.4 mamirioni emakore ekare anosimbisa kuvapo kwayo muzvinyorwa zvemafosili panguva ino. VaPaleontologist vanofunga kuti Eoraptor yakafanana nemadzitateguru akajairika emadhinosaurs ese; kana izvi zviri zvechokwadi, hunhu hwayo hunoratidza kuti madhinosaurs ekutanga aive madiki, bipedal zvinoparadza. Kuwanikwa kweakakura, dinosaur-akafanana neTriassic madzinza akadai saMarchus Lagerodon uye Triassic madiki muArgentina anotsigira maonero aya; ongororo yakawanikwa yezvicherwa zvinoratidza kuti idzi mhuka dzaive zvidiki bipedosaur, Rhynosaurs, Rhynosaurs?
