Prehistoric nonavian dinosaurs are one of the many types of creatures that have appeared in Mario games. A few different dinosaur species exist in Mario's world, such as Yoshis, Birdos, and Rexes.

Super Mario Bros. film
In the Super Mario Bros. live-action film, an alternate, unnamed version of Earth is revealed to exist. This parallel Earth was brought into creation when the meteorite struck the true Earth 65 million years ago, causing spatial and dimensional disturbances, resulting in the creation of the alternate Earth. Some dinosaurs were then flung into this parallel world, while their kin went extinct on Earth.

On this Earth, various types of dinosaurs evolved into humanoid creatures, though some, such as Yoshi, seemed to have retained their reptilian forms. Aside from one rundown city, Dinohattan, this Earth is a desert wasteland, lacking various resources.
