One undeniable truth remains whether you’re a child or an adult: Dinosaurs are fascinating. While encountering one would likely be terrifying, the notion that these massive (and often dangerous) creatures once roamed the same Earth we occupy is mind-boggling. Although movies like Jurassic Park have provided a wealth of information about various dinosaur species—complete with iconic quotes—there are several misconceptions you may hold, particularly regarding aquatic dinosaurs.
The truth is, there’s technically no such thing as aquatic dinosaurs. (Surprising, right?) According to the book Dinosaurs: The Very Latest Information and Hands-On Activities From the Museum of the Rockies by Liza Charlesworth and Bonnie Sachatello-Sawyer, all dinosaurs were land-dwelling creatures. While some may have been capable of swimming, these excursions were temporary. No dinosaurs inhabited oceans, lakes, or rivers permanently.
It’s a challenging concept to wrap your head around since it seems natural to assume dinosaurs dominated every aspect of the planet: land, air, and sea. However, just as you wouldn’t find a fierce lion swimming deep in the ocean, you won’t find any dinosaurs there either, based on current discoveries.
This realization raises even more questions. So, let’s explore the aquatic realm during the Mesozoic Era. Hold on tight!
What Aquatic Creatures Did Exist?
If aquatic dinosaurs weren’t a reality, what kind of marine life thrived during the Mesozoic Era? Paleontologists classify these beings as swimming reptiles. Although they weren’t technically dinosaurs, they were still formidable predators you wouldn’t want to encounter in the water.
Here are some noteworthy sea creatures from that time:
- Ichthyosaur: Known as “fish lizards,” these creatures resembled fish and could grow up to 10 feet, or even 40 feet in length.
- Plesiosaur: These giant carnivorous reptiles had long necks and short tails, preying on weaker creatures like Ichthyosaurs.
- Basilosaurus: An ancient whale with sharp teeth, reaching lengths of 50 to 80 feet.
- Helicoprion: This shark-like predator, measuring about 15 feet, is infamous for its razor-sharp, saw-like teeth—definitely a source of nightmares.
- Pliosaur: A carnivorous reptile characterized by a large head, short neck, and tear-shaped body.
- Nothosaur: Resembling crocodiles, these reptiles had long, flat tails and sharp teeth.
- Mosasaur: These aquatic lizards, often referred to as the T-Rex of the seas, boasted snake-like bodies and elongated snouts.
What Marine Creatures Were Featured in Jurassic World?
Fans of the franchise may remember a colossal sea creature making several striking appearances in Jurassic World. While many assumed it was a true dinosaur, it’s actually a cloned version of the Mosasaurus—a species of mosasaurs. Despite not being a dinosaur, this creature proved to be just as lethal as any land-based predator.
So, the massive being that effortlessly devoured a Great White Shark and pulled the hybrid T-Rex into the depths of the ocean was essentially a giant aquatic lizard. Your mind is officially blown!

Summary
Dinosaurs, while captivating, never lived in water permanently; the aquatic creatures of their time were actually swimming reptiles. Understanding this distinction enhances our appreciation for the diverse life forms that existed during the Mesozoic Era.
