Living Dinosaurs

Go To
Some writers think Everything's Better with Dinosaurs, but in this case dinosaurs were not brought back with cloning technology nor due to time travel. Non-avian dinosaurs just survive the mass KT extinction up until modern (or even future) times.

As dinosaurs are pretty well known, the in-universe explanation for them to be mostly undiscovered all this time often involves a Lost World somewhere in the far and unexplored regions of Earth, or even Beneath the Earth or inside a Hollow World, where dinosaurs manage to remain untouched, or in some cases, on a different planet. In some cases they evolved into something new, often Reptilian Conspiracy or Ultraterrestrials.

Although this trope uses the term dinosaur, due to Artistic License – Paleontology it is not uncommon that non-dinosaur prehistoric beasts may also be included as examples, like plesiosaurs and pterosaurs. But remember, dinosaurs and cavemen living together was a common trope in old media, but is more a case of Critical Research Failure than the intentional use of this trope.


A Sub-Trope of Not So Extinct, and very commonly use in works with Our Cryptids Are More Mysterious; supertrope to Mokele-Mbembe. Compare with Stock Ness Monster (often portrayed as a surviving plesiosaur) and Dinosaurs Are Dragons (for the idea that dinosaurs actually inspired the dragon myth). Domesticated Dinosaurs maybe result if people manage to tame them. Overlaps with Medieval Prehistory in works that use a real medieval setting (as opposed to a medievalish fantasy land).

    Live Action TV 
  • In the Chilean puppet show 31 Minutos, one of the songs of the show is Dinosaur Anacleto, the only surviving dinosaur on the Earth that even became a showbiz personality. The song is in general a melancholic one, since the main theme of the song is how lonely Anacleto is because all his dinosaur friends are dead and he wants friends again.
  • Dinosaurs surviving to modern times and developing sapience is the central plot behind the TV show Dinosapien.
  • Recurring culture the Silurians/Sea Devils/Homo reptilianote  in Doctor Who are sentient, vaguely-human-shaped dinosaurs from Earth.

    Religion and Myths 
  • Some Creationists believe that non-avian dinosaurs survive up to historical times and co-exist with modern humans. Some even think that dinosaurs still exist and are the origin of several cryptids like the Loch Ness Monster.
  • As mentioned in the film section, some cryptids around the world are thought to be living dinosaurs. The first one was probably the Loch Ness Monster. Africa has several, especially around the Congo region with the Mokèlé-mbèmbé (possibly a surviving sauropod) as the most famous one. There's also the Ropen (an alleged living pterodactyl) in Indonesia. Most modern cryptozoologists do not take these claims seriously and, although they do believe some of these animals could be undiscovered species, most of them do not think they are literally [non-avian] dinosaurs.

    Tabletop Games 
  • The Call of Cthulhu book Blood Brothers offers a series of one-off adventures, using the game's rules but unrelated to the main Cthulhu Mythos setting, and mostly pastiching various horror subgenres. One of these, The Land That Time Ignored, opens thus:
    The Land That Time Ignored tells of explorers' adventures in 1932, in a valley filled with giant dinosaurs which just happen to look like iguanas with rubber stuff cemented onto them. The purpose of this scenario is to attempt to recapture the spirit and style of the Lost World type of movie, in which all dinosaurs are flesh-eaters, and there are always beautiful cave-girls to rescue.
  • Claim the Sky: One of the Inner Earth caverns is home to large numbers of otherwise-extinct animals including dinosaurs.
  • Most editions of Dungeons & Dragons (as well as the unofficial D&D spinoff Pathfinder) will offer statblocks for various dinosaurs (and other technically-not-a-dinosaur animals like elasmosaurus and pteranodon), but it's usually up to the Dungeonmaster to work out how they fit into this world. A lot of the pre-written campaigns settings will sequester them in a Lost World, but a few worlds - such as Eberron - have dinosaurs as just another category of animals that roam the world, and are often kept as beasts of burden.

    Video Games 
  • Carnivores is set sometime after the discovery of a planet inhabited by dinosaurs and other prehistoric reptiles and said planet's purchase by a safari company who turn it into a game preserve where the player can hunt any of seven species.
  • In Command & Conquer: Red Alert 2: Yuri's Revenge, the Soviets commandeer the Allied time machine in their campaign but accidentally travel too far back in time to the Cretaceous, where they're attacked by Tyrannosaurs. It's possible to acquire one of them as a unit and take it back to present-day San Francisco.
  • Oakwood is set in an abandoned campground that turns out to apparently have a prehistoric pocket ecosystem in it. This allowed the dinosaurs within said pocket ecosystem to be able to survive and thrive into the modern day, much to the horror, and later doom, of a seven member group of young campers.
  • Super Robot Wars: Being a Massive Multiplayer Crossover that features the above mentioned Getter Robo, has the Dinosaur Empire as one of the recurring antagonists.
  • Tomb Raider:
    • The first game and its remake has a T. rex and raptors living in a lost valley in Peru.
    • Tomb Raider II has a pair of T. rex living in a secluded area near the Great Wall of China.
    • Tomb Raider III once again features raptors and a T. rex on a South Pacific island, this time being joined by flocks of Compsognathus. The expansion pack has Pteranodons living in a secluded volcanic area.

  • The Redacverse got human-looking dinosaurs like the Matthewsaurus, still alive in the present day, and the Therrysaurus, who survived as a fossil. Several other dinosaurs also exist, including normal-looking ones, but they aren't all incredibly long-lived.

    Web Video 
  • The April Fools' Day episode of TierZoo discussed the Loch Ness Monster and the Mokèlé-mbèmbé during its look at cryptid builds. The former was hypothesized to be a surviving Plesiosaur which dominated the oceans back then, while the latter was hypothesized to be a pygmy sauropod from the Congo Jungle. Both were considered to be top-tier cryptid builds, the former due to its huge size and capability to find food easily, the latter because its dwarfism ironically gave it better survivability since it meant a far smaller food requirement than regular sauropods while still being large enough to deter would-be predators.

    Real Life 
  • Birds are considered dinosaurs. It's now accepted by an overwhelming number of biologists that birds are simply a group of flight-capable theropods that survived the mass extinction, especially now that it's been discovered that there were a large number of dinosaur species that had feathers. While birds might not look much like one's concept of dinosaurs, there are several things to consider. Not only were dinosaurs as a whole a very diverse group, but not all dinosaurs evolved into birds; rather birds were just one branch on the family tree. The closer one gets to birds on the family tree, the more bird-like the non-avian dinosaurs look to the point distinguishing between what is an early bird and what is a bird-related non-avian dinosaur is almost impossible. Remember that early birds had mouthfuls of teeth, unfused wing fingers with sharp claws, and long bony tails; essentially looking like scaled down versions of feathered theropod dinosaurs with bigger arms.
    • Additionally, birds still carry the genes for long tails and toothy snouts that most modern species lack, but lack the activator enzymes necessary to develop them. One scientist made dinosaur-faced chicken embryos by accident while doing genetic research.
  • There's a growing theory that some non-avian dinosaurs may have survived into the early Paleocene epoch. Some cryptozoologists connect this theory to modern sightings of non-avian dinosaurs, even if it only moves the date of the last non-avian dinosaurs from sixty-six to sixty-four million years ago at best. That said, evidence for Palaeocene dinosaurs is highly controversial.
  • Contrary to popular misconception however, alligators and crocodiles are not dinosaurs. They and dinosaurs are part of the same clade alongside the extinct pterosaurs, archosaurs; so they are more closely related to each other than either is to other reptiles but aren't in each other's distinct family line. It be more correct to call them "cousins" of dinosaurs, thus making them the closest extant relatives to all living birds. Looking at a cladogram shows just how big an impact the K-Pg extinction left, with birds and crocodilians sitting on either side of a vast gulf of species rendered exinct at the end of the Cretaceous. This relation is actually the reason why crocodilian meat tastes like chicken or turkey.
  • Famously, a species of conifer which flourished in the Triassic period is still extant in Australia, surviving for over 200 million years.
