Kwakataurwawo kuti Dinosauria inotsanangurwa maererano neMRCA yeMegalosaurus neIguanodon, nokuti idzi dzaiva mbiri dzemadzinza matatu akataurwa naRichard Owen paakaziva Dinosauria. Tsanangudzo mbiri idzi dzinoita kuti mhuka imwe chete idzi dzinzi madinosaurs: "Dinosauria = Ornithischia + Saurischia", inosanganisira ankylosaurians (zvose zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvinodya zvin Muzvinyorwa zvetsika, shiri dzairangarirwa seboka rakaparadzana iro rakanga rachinja kubva kumadinosaurs, hurongwa hukuru hwakasiyana. Zvisinei, ruzhinji rwema paleontologist anhasi ane hanya nemadinosaurs anoramba nzira yechinyakare yekuronga achitsigira phylogenetic taxonomy; nzira iyi inoda kuti, kuti boka rive rechisikigo, vazukuru vose vemitezo yeboka vanofanirawo kuverengerwa muboka.
