History Manga / DinosaurSanctuary

* StockDinosaurArchetypes: [[ZigZaggingTrope Zig-Zagged]]; while several types of dinosaurs are shown, much of their usual depictions in pop culture are subverted, instead providing them with more natural, believable personalities that can be seen with almost any other animal. The ''Giganotosaurus'' and ''Tyrannosaurus'' that reside in Enoshima Dinoland are shown as placid animals that are rather needy and childish in nature, given they rely on their human keepers to keep them happy and satisfied, Masaru the ''Triceratops'' is a GentleGiant, Eiger the ''Spinosaurus'' a docile fish-eater who was unable to fish properly until his enclosure was expanded, and Momiji the ''Stegosaurus'' is a MellowFellow. That said, the ''Centrosaurus'', ''Troodon'', and ''Pachycephalosaurus'' have more typical personalities, but still shown in a realistic light, keeping them from being monstrous. [[spoiler:Even the most aggressive dinosaur that is shown, an ''Allosaurus'' named Ichigo, only became dangerous because she became panicked by construction workers and killed her keeper out of distress, which unfortunately caused mass panic to label dinosaurs as untamable {{Prehistoric Monster}}s and taint the reputation of dinosaur sanctuaries, something which the protagonists seek to rectify.]]

-->'''Kaidou:''' Dinosaurs aren't monsters, but they aren't pets either. Every living thing has a comfort zone that must be respect or else people find out just how fragile we are. It doesn't matter how solid your security is. Fail to respect that distance for a second, and it might be your last.

* AllAnimalsAreDogs: The second volume heavily deconstructs this trope, showing that while dinosaurs are not monsters, they are still wild animals that are often dangerous, and should not be treated like a pet dog or cat. [[spoiler:Yamaga was killed by the ''Allosaurus'' he had cared for for fifteen years because he believed she had bonded with him, but when frightened by an unexpected event, she lashed out unpredictably as a wild animal does, mauled him to death, and almost escaped]]. Suzume later acts as a surrogate parent for a baby ''Troodon'' but finds even caring for a small hatchling is really tough because of how wily, energetic, and destructive it is.

* AuthorAppeal: Author Itaru Kinoshita's favourite dinosaur is ''Giganotosaurus''. Naturally, its the focus dinosaur of the first chapter and the first animal Suzume works with at Enoshima Dinoland.

** The dinosaurs are generally extremely accurate as to scientific thought in the 2020s regarding their appearance and behaviour, right down to the feathers on the ones you'd expect to have them. However, there are some minor things here and there.

** A two-parter in Volume 4 (Chapters 20 and 21) involves Suzume and Kaidou getting called into recapturing a ''Velociraptor'' that escaped from dino-smugglers in Yokohama and running loose in Kamakura. Heavily downplayed as the raptor is [[ShownTheirWork based on the real animal]] rather than the [[RaptorAttack bloodthirsty killers]] from ''Franchise/JurassicPark'', so it doesn't really cause any damage beyond scaring people and stealing a koi from a raccoon.

* EscapedAnimalRampage: [[spoiler:The 2006 incident was one of these, with Enoshima's ''Allosaurus'' Ichigo, spooked by construction noises, killed her keeper and then injured herself in a panic, forcing the zoo to put her down. While no visitors were harmed in the incident, it shocked the world and stirred controversy, killing public interest in dinosaurs and even driving Suzume's father to suicide.]]

* DreamSequence: One in Volume 4 has Suzume dreaming of fleeing a number of dinosaurs with Kirishima on a motorcycle. She wakes up wondering if she's been working too hard lately.

*** Another reference to ''Jurassic World'' occurs in a bonus manga that came in Volume 4, in which Suzume and Karin are on a motorcycle while getting chased by a pack of ''Deinonychus''.

The series is also notable for its hard aversion of ArtisticLicensePaleontology. All the dinosaurs you expect to have feathers are as fluffy as they should be, and an actual paleontologist, Dr. Shin-ichi Fujiwara, was consulted by Kinoshita for information on depicting the dinosaurs with the correct behaviours and anatomy, and each chapter is accompanied with a detailed scientific explanation justifying how the dinosaurs are portrayed in the story. Likewise, the dinosaurs are also anything but {{Prehistoric Monster}}s, and their interactions with their handlers are not too different from what real-life zookeepers deal with when it comes to modern animals.

!! Tropes:

** Mostly averted. The dinosaurs are generally extremely accurate as to scientific thought in the 2020s regarding their appearance and behaviour, right down to the feathers on the ones you'd expect to have them. However, there are some minor things here and there.

** Also addressed InUniverse. It's shown that some of the common misconceptions about dinosaurs (like birds not being dinosaurs, ''Dilophosaurus'' having a frill and spitting venom, ''Pachycephalosaurus'' headbutting each other, etc.) are still prevalent in this timeline, with the characters and information signs working to dispel them.

** The ''Tyrannosaurus'' is depicted as having a full body coat of fluff. While this was commonly accepted in the mid-2010s, it fell out of favor following further research on fossil skin impressions of ''T. rex'' that suggest it was most likely predominantly scaly, with feathering, if any, being relegated to the back. However, this is fixed in later chapters, showing adult ''Tyrannosaurus'' as sparsely-feathered as they should.
** The name ''Troodon'' is used here with Enoshima's Niko and Vena, despite the name having been rendered scientifically dubious following an extensive re-examination of ''Troodon'' fossils reassigning the vast majority of material to ''Stenonychosaurus'' (which had been previously sunk into the ''Troodon'' genus in the 1980s).
** The maniraptorans, although commendably portrayed as being thickly feathered, are depicted with half-formed proto-wings rather than the large bird-like wings they would've more likely have had.
** The ''Edmontosaurus'' that appears in an ImagineSpot in Chapter 11 is shown without the row of raised scales along its back, as we now know they would have had based on some exceptionally well-preserved specimens. It does seem to have a ridge along its back which suggests the scales are hidden underneath skin, based on a hypothesis that is now considered unlikely.
** The ''Stegosaurus'' have only one claw on the forefoot like a sauropod, rather than two.

* GiantFlyer: Averted. Enoshima Dinoland has four pterosaur species -- ''Pterodactylus'', ''Rhamphorhynchus'', ''Pterodaustro'' and ''Ctenochasma'' -- none of whom are giant[[note]With a six foot wingspan, ''Rhamphorhynchus'' would've been the largest of these four, followed closely by the four foot ''Pterodaustro''; ''Pterodactylus''' wingspan is only three feet and ''Ctenochasma'' is the smallest at two feet[[/note]]. It's implied that the big boy pterosaurs (''Pteranodon'', ''Quetzalcoatlus'', etc.) are reserved for the more elaborate dinosaur zoos.
