Female Deinosuchus is a gigantic Deinosuchus that was rescued by Nigel Marven and his crewmen. She was feeding on a Parasaurolophus (that got killed by another Deinosuchus) with her clan. Nigel builds up a wooden pen to prevent her from escaping. She finally gets to the 21st century and now she goes to her enclosure. When the Mass-Break Out started, Matilda the Tyrannosaurus chases Nigel and the Deinosuchus jumps out of her enclosure and she tries to snap Matilda with her jaws, but missed. But thanks to the Deinosuchus, Nigel is still one step a head of Matilda.
