Pliosaurs were large aquatic reptiles that existed during the days of the dinosaurs, eons before the ice ages.


Large and compactly-built, pliosaurs swam through the oceans of the dinosaur age, hunting slow-moving prey, usually reptiles. Pliosaurs were thickly-built with four large, flat fins used for moving through water, and blunt, neckless heads on which were large mouths filled with hard teeth strong enough to break through an ice floe. Coated with armor-like scales and ridges, pliosaurs occasionally used their heads to ram into prey underwater, and could jump high distances out of the waters they swam in.


Pliosaurs, swimming in the waters in the pursuit of prey until a million years ago before the ice age. A single pliosaur, though, named Maelstrom, along with an ichthyosaur named Cretaceous were frozen in the waters they swam in and thawed out in the ice ages, finding prey in that epoch.

Behind the Scenes

  • True pliosaurs had longer necks than is shown in Ice Age: The Meltdown, along with a longer crocodilian snout and no plates or scutes on their hides. It more closely resembles a Placodus, a Triassic marine reptile that fed on shellfish.
  • The book Ice Age: The Great Escape states that both Cretaceous and Maelstrom were frozen one million years before the events of Ice Age: The Meltdown, but both ichthyosaurs and pliosaurs were extinct for tens of millions of years before the ice ages.
