Cretaceous and Maelstrom

Cretaceous and Maelstrom are the two main antagonists of the 2006 animated film Ice Age: The Meltdown. They are two sea creatures that were frozen in ice and freed when the ice melted. Cretaceous was a slender iris female Metriorhynchus and the primary antagonist of the movie and Maelstrom was a obese teal male Globidens and the direct secondary antagonist.

History
Despite being the main antagonists, their role in the movie is small. They were first seen in the movie thawing out in a melting pack of ice. Their first victim is Fast Tony's Glyptodon sidekick Stu. They made one scene in the film when they tried to eat Manny, Sid, Diego, Ellie, Crash, and Eddie when they were crossing a frozen area of water. Cretaceous wanted to eat Manny because he was the biggest animal in the whole herd. Despite almost loosing their lives, the heroes managed to escape. They appear later in the film when Ellie is trapped in a cave from the rising flood. When Manny and his friends went to rescue Ellie, Cretaceous and Maelstrom tried to eat them. However, Manny tricks them into hitting a log wedged between a large rock, causing the rock to fall and crush the two vicious reptiles.

In the movie novel Ice Age: The Great Escape, they were not killed from the large rock after all the water was drained there were taken away along with the water and were never seen again all the water went to the ocean the two reptiles live they lives hunting for other prey to eat.
