Peltephilus, the horned armadillo, is an extinct species of dog-sized, armadillo xenarthran mammal which first inhabited Argentina during the Oligocene epoch, and became extinct in the Miocene epoch. Notably, the scutes on its head were so developed that they formed horns protecting its eyes. Aside from the horned gophers of North America, it is the only known fossorial horned mammal. Although it had traditionally been perceived as a carnivore because of its large, triangular-shaped teeth, Vizcaino and Farina argued in 1997 that Peltephilus was a herbivore.
Peltephilus appears as a Glacier Park animal in Jurassic Park: Builder. The area is occupied by three animals of the species.
The animals is mentioned in the Henry Wu mission "Thunder From The Ground". The Peltephilus is one of the species that was scared by the sound of cracking glaciers. They refused to eat or let anyone go near them. You have to level-up Peltephilus to level 18 to finish the mission.
