History Main / AquaticHadrosaurs

* Charles Robert Knight, a paleoartist who lived from 1874 to 1954, has a few paintings where he depicts hadrosaurs according to the classic portrayal. [[https://en.wikipedia.org/wiki/Edmontosaurus#/media/File:Knight_hadrosaurs.jpg This example]] includes two ''Edmontosaurus'' individuals, one of which feeds on aquatic plants.

* Ducky from the ''WesternAnimation/TheLandBeforeTime'' series is supposed to be some kind of hadrosaur, and she's the swimmer one among the five main heroes. "Swimmer" appears to be [[CallARabbitASmeerp the term dinosaurs use for a hadrosaur]], reinforcing this stereotype. That said, Ducky herself doesn't spend much time in the water. The sequels, however, call hadrosaurs "bigmouths", while "swimmer" is instead used as the word for aquatic reptiles such as plesiosaurs (though it is still occasionally used for hadrosaurs, or at least Ducky). Adults are shown 9 out of ten times wadding and feeding on aquatic plants like reptilian moose, though they are never shown swimming.

* ''WesternAnimation/JurassicWorldCampCretaceous'': Played straight by the ''Parasauroluphuses'' that live in the underground river area. Given that they also have [[BioluminescenceIsCool bioluminescent patches that are wildly implausible]], it's likely they were genetically modified to be semi-aquatic. The ''Ouranosaurus'' also qualifies as this.

* ''Film/{{King Kong|2005}}'' (2005): The corpse of a ''Ligocristus'', a fictional lambeosaurine dinosaur, appears. According to the film's companion book, ''The World of Kong'', it's noted to swim to small islets to lay its eggs during dry seasons. They are skilled swimmers, using this as a way to escape land predators. Possibly justified by the fact that it's not a prehistoric hadrosaur.

Compare AquaticSauropods, which addresses outdated aquatic depictions (although for different reasons) of herbivorous dinosaurs such as ''Brachiosaurus'' or ''Brontosaurus''.

* The "Rite of Spring" segment from ''{{WesternAnimation/Fantasia}}'' features several species of hadrosaurs, namely ''Parasaurolophus'', ''Corythosaurus'', ''Edmontosaurus'', and ''Kritosaurus''. They are depicted as swamp animals feeding on aquatic plants and run away in the water when a ''T. rex'' approaches.

* ''GoDiegoGo'': In the episode "Diego's Great Dinosaur Rescue", Maia the ''Maiasaura'' is shown to be a good swimmer. In the episode, Alicia tells the viewers that "''Maiasauras'' and a lot of dinosaurs swim", which unfortunately isn't true.

* In the Creator/JuliaDonaldson picture book ''Tyrannosaurus Drip'', the duck-billed dinosaurs live in a river environment, similar to actual ducks.

* Briefly mentioned in the ''Series/WalkingWithDinosaurs'' episode "Death of a Dynasty", when it's stated that hadrosaurs evolved in lush swamps, subtly suggesting the idea that hadrosaurs were semi-aquatic. The ''Anatotitan'' in the episode itself are only ever shown on land, though.

* In ''Ride/JurassicParkRiverAdventure'', ''Parasaurolophus'' play an almost entirely aquatic role, with the one that (according to the ride narrative) bumps the riders' boat off course being seen neck-deep in water when it briefly surfaces after bumping against the boat. It being portrayed as aquatic is for the sake of practical reasons regarding hiding the machinery of the animatronics.
* A herd of ''Edmontosaurus'' were present in the Primeval World Diorama segments of Universe of Energy and its later retool Ellen's Energy of Adventure bathing under a waterfall and likewise positioned in a small pool of water.

* The ''Parasaurolophus'' in ''VideoGame/ARKSurvivalEvolved'' are better swimmers than the other dinosaurs, using this as a means of protection.

* Discussed briefly in ''WesternAnimation/DinosaurTrain'' in the ''Corythosaurus''-centered episode. When the main characters are learning about the function of its crest, Buddy asks Cory if it's used for breathing underwater, Don, due to being more of a {{Cloudcuckoolander}}, asks her if it's used for flight, and Tiny asks her if it's related to the music they make. Cory denies the first two questions and affirms the third one.
* Inverted with Rocky in ''{{Literature/Gigantosaurus}}'', who's a ''Parasaurolophus''. His friends are able to swim just fine, but he's shown to be afraid of water because he can't swim (although he later learns to). Interestingly, [[ArtisticLicensePaleontology he has a hole in his crest]], even though the lack of one is one of the very reasons why the theory about his species being aquatic was disproved.

For more than a century after their discovery in the 1850s, hadrosaurs were thought to have been semi-aquatic animals that lived in swamps and ate aquatic plants. There are a few factors that led to this (ultimately disproven) hypothesis. For one thing, their generic name "duck-billed dinosaurs" comes from their broad and flat rostral bones which are similar to a duck's bill (most prominently seen in ''Edmontosaurus'', also known as ''Trachodon'' or ''Anatotitan'' in older works), which may have led to the assumption that they fed on aquatic plants. Another thing is the presence of soft tissue that was believed to be webbing for the fingers but turned out to be a deflated fleshy pad, built for walking on dry land. Last, but not least, some hadrosaurs sported head crests that were hypothesized to have functioned as some kind of snorkel or air-storage space; however, they lacked a hole in the crest and the stored air wouldn't be enough for animals of their size, making both theories unlikely. Instead, their crests functioned like resonating chambers used to amplify their calls but may have also been used as a visual signal and for display.

* ''Franchise/StarWars'': Kaadus, the primary riding animals used by the Gungans, resemble slender, armless hadrosaurs, live in swamplands, and are established in supplementary materials to be agile swimmers and divers. The Gungans themselves also somewhat resemble Hadrosaurs, save for standing upright and lacking a tail.
