Dinosaurs (恐竜 Kyōryū) are a diverse group of saurians. The fossil record indicates that birds evolved from theropod dinosaurs during the Jurassic Period and, consequently, they are considered a subgroup of dinosaurs by many paleontologists. The diverse group dinosaurs are still alive in the Dragon Ball universe, and they live on Earth, as well as on Namek and Cretaceous.
There are several types of dinosaurs throughout Dragon Ball, Dragon Ball Z and Dragon Ball GT, including Triceratops and Apatosaurus. There are also dinosaur species that only exists in the Dragon Ball universe: Paozusaurus (a T. rex type dinosaur) and Inflatasaurus Rex. In the Dr. Slump chapter "Hello, Moon!", it is explained why dinosaurs coexist with Earthlings in the Dragon World: when Arale Norimaki traveled back to the prehistoric ages, she saved a vast number of dinosaurs and other prehistoric creatures from the Mass Extinction when she pushes a falling meteorite back into space. This also resulted in the creation of the Earth's moon in the Dragon World. In the special edition of the movie Dragon Ball Z: Battle of Gods, the God of Destruction Beerus claims that he went to Earth once and dinosaurs took a rude attitude with him, so he wiped them out. Like their reality counterparts most of the dinosaurs range in sizes from 0.5 (2 ft) to over 30 meters in length and stood around 0.5 (2 ft) with some species exceeding up to 9–10 meters (30–32 ft) tall. However within the Dragon Ball universe; numerous of dinosaurs have unrealistically grown to kaiju scale, towering over mountains and buildings to a great extant.
Emperor Pilaf Saga
When Goku leaves Bulma to bring Turtle to the beach, a dinosaur is seen walking near Bulma's Capsule House, scaring her. Shortly before meeting Yamcha, Chi-Chi encounters and kills a T. rex by decapitating it using the blade on her helmet. The appearance of this T. rex is much more accurate to its real-life counterpart than those that appear later in the series.
In Monster Carrot's Village, dinosaurs serve as transportation.
A large dinosaur, possibly a Triceratops, is seen walking past Yamcha, Puar, Bulma and Oolong shortly after their ship crashes in a forest. In addition to this, a T. rex frequently chases Goku and Krillin as part of their training under Master Roshi. The appearance of this T. rex is noticeably somewhat different than the ones that later appear in Dragon Ball Z. It's most probable that this T. rex is actually an oversized Ceratosaurus.

During a series of filler episodes involving Krillin, Gohan, and Bulma on a fake Namek, a gigantic dinosaur picks up a Dragon Ball and carries it into a lake full of acid, where it is killed.
