Mario Kart series
A one-horned, blue-gray sauropod appears in Mario Kart: Double Dash!! in the Dino Dino Jungle course, where it is located at the course's overpass. It is first encountered below the overpass, stomping the ground and flattening any racers that are too close to its feet. It is then encountered while going through the overpass, but cannot be interacted with there.
As Dino Dino Jungle returns as a retro course in Mario Kart 7, the dinosaur returns as well, behaving exactly as same as it did before. The dinosaur's head can also now be interacted with at the overpass; it serves merely to block any racers gliding through the area.
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.
