* ''Series/PowerRangersDinoCharge'': The extinction of the dinosaurs was caused by an earlier defeat of Sledge where a bomb was snuck onto his ship, and the resulting explosion sent the asteroids he collected raining down all at once upon the Earth. After altering the past to defeat Sledge before the asteroid-triggering defeat, the Rangers return to the present day to find that their museum has become a dinosaur sanctuary since dinosaurs were never destroyed. Later crossover specials reveal that the ''Dino Charge'' reality is an AlternateUniverse to the one most other ''Power Rangers'' seasons take place in, where dinosaurs are still extinct.

This trope is distinct from the LostWorld genre, where a small enclave of prehistoric animals is isolated from the "modern world". In this trope, the ''entire timeline'' is changed so that dinosaurs -- or whatever other prehistoric animals the writer is focusing on -- have survived to the present. [[ArtisticLicenseBiology Despite the fact that, logically, humans would not have evolved in a world where dinosaurs did not become extinct]], they will often be shown to [[InSpiteOfANail exist anyway]] because MostWritersAreHuman. In many cases, the dinosaurs will be shown as [[EvolutionaryStasis little different from their prehistoric ancestors]]. Other times, however, the writers will engage in SpeculativeBiology, creating new fictional species descended from real ones.

* ''Franchise/DragonBall'' is set in a world where dinosaurs, as well as talking animals and aliens, co-exist with humans. At one point, [[DestroyerDeity Beerus]] mentions in an off-hand comment about how he offed the dinosaurs on Earth because they annoyed him, which contradicts the fact that they're frequently shown there.

* In ''Anime/DoraemonNobitaAndTheKnightsOnDinosaurs'', unknown to humanity, dinosaurs still live in an underground civilization and have evolved into a human-like state. [[spoiler:At the end of the movie it's revealed that this outcome was caused by Doraemon when he, in a last resort to save everybody and escape the destruction of the meteor, activates the Pop Basement gadget and evacuated all dinosaurs into it.]]

* ''Film/AztecRex'' makes use of this trope in a historical setting, As the Spaniards begin arriving in Mexico a group led by UsefulNotes/HernanCortez discover a valley where a pair of surviving T-Rex’s who are the LastOfTheirKind and referred to as “Thunder Lizards” by the local Aztecs who worship the dinosaurs.

* ''VideoGame/PaleoPines''[='=] [[https://store.steampowered.com/app/1202200/Paleo_Pines/ Steam page]] says evolution took the path of "survival of the kindest" in this universe, so humans live alongside easily-tameable prehistoric creatures. Most of them are non-avian dinosaurs, but there are a few others such as ''Dimetrodon'' (a synapsid), ''Desmatosuchus'', and ''Postosuchus'' (both crocodylomorphs).

* The [[https://store.steampowered.com/app/1202200/Paleo_Pines/ Steam page]] for ''VideoGame/PaleoPines'' says evolution took the path of "survival of the kindest" in this universe, so humans live alongside easily-tameable prehistoric creatures. The pre-release footage and demo focus on non-avian dinosaurs, but the [[https://www.paleopines.com/dino-journal Dino Journal]] on the official website also shows ''Dimetrodon'', ''Desmatosuchus'', and ''Postosuchus'', which are correctly not called dinosaurs.

* ''Literature/AnonymousRex'' takes place in a world where dinosaurs didn't go (completely) extinct, but eventually evolved into humanoid forms and, in order to [[TheMasquerade prevent mankind from finding out about them and kill them]], developed secret societies and [[LatexPerfection perfect disguise suits]]. The protagonist, private detective Vincent Rubio, is one of them -- a ''Velociraptor'', to be exact.

* In two of the AlternateUniverse{{s}} Ford visits in ''Literature/GravityFallsJournal3'', the dinosaurs never went extinct. In one universe, they remained animalistic; in the other, they became sapient.

* In ''ComicStrip/{{Dilbert}}'', the titular character makes a calculation that dinosaurs did not all go extinct. The ones that survived went into hiding. Out come the dinosaurs Bob and Dawn, who confirm his claim and that the idea that the dinosaurs were wiped by a giant asteroid was highly exaggerated; it was a slightly large meteor that fell on top of one dinosaur who survived (although the two are implied to be [[UnreliableNarrator making this up]]).

* In ''ComicStrip/{{Dilbert}}'', dinosaurs aren't extinct; they're just hiding in your furniture. Bob the Dinosaur managed to evade humans for years thanks to wearing tennis shoes for fast running. All of the "fossils" that are discovered in modern times were purchased at dinosaur prank novelty stores and thrown into tarpits just to fool people.

* In the world of ''WesternAnimation/OKKOLetsBeHeroes'', small dinosaurs take the place of wild creatures like squirrels or pigeons. Gar's Bodega has a baby ''T. rex'' as a mascot, named Baby T; [[spoiler:the GrandFinale shows him fully grown, but still gentle.]]

* One of AlternateUniverse{{s}} Ford visits in ''Literature/GravityFallsJournal3'' is one where the dinosaurs never went extinct.

* Invoked in ''[[VideoGame/TastyPlanet Tasty Planet: Back in Seconds]]'' when the Grey Goo accidentally swallows a meteor that otherwise would have caused the dinosaurs to go extinct in the Mesozoic Era. This causes an alteration in the timeline, leading dinosaurs to suddenly appear in the present. As a bonus point, the scientists' lab cat changes to a dinosaurian species.
