The Diatryma is the second carnivore available to hunt in Carnivores Ice Age, and is the only pointable animal that is not a mammal. It behaves very similar to the Allosaurus and Velociraptor from Carnivores 2, like jumping to attack its victims and eating their corpses instead of swinging them around in its mouth. It is also commonly seen while not being hunted. Unlike other animals, the Diatryma is not afraid to cross water.
The Diatryma is also the only creature in Carnivores Ice Age that the Observer Mode works effectively on. The Diatryma appears to be omnivorous to a small extent. While walking the Diatryma will occassionally stop and graze on what could be plants, fruits and seeds, and or insects.Its dinosaur call sounds like a chilling eagle sound.
