An Iguanodont shortly before collapsing. (Land of Giants)

This iguanodont was a genus of basal iguanodontian ornithopod dinosaur which lived during the middle and late Cretaceous period in Patagonia.


The iguanodont is shown as prey to larger predators like the giant theropod Giganotosaurus and the crocodylian Sarcosuchus.

Chased by DinosaursEdit

Land of GiantsEdit

When Nigel Marven entered the Cretaceous he spooked and scared away a herd of iguanodonts by accident. The next day Nigel saw one of them fleeing and followed a trail of blood running down a stream. He found a severely injured Iguanodont slowly succumbing to its wounds. He later saw a Giganotosaurus feeding on the carcass. It then held it aloft and carried it away.

Whilst driving through open plains Nigel saw an iguanodont running beside his vehicle. He then looked behind him and saw the reason why it was running - a Giganotosaurus was chasing it down.


  • It uses a recycled model of Iguanodon. The color was just changed.
  • It was identified as "iguanodont" in Chased by Dinosaurs.
