Peltephilus, the horned armadillo, is an extinct genus of armadillo xenarthran mammals that 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. Aside from the horned gophers of North America, it is the only known fossorial horned mammal.[1] P. ferox had skull about 11.7 centimetres (4.6 in),[2] and estimated body mass is around 11.07 kilograms (24.4 lb).[3]
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.[4]
Taxonomy
The genus was originally classified as belonging to the family Chlamyphoridae, but in 2007 was placed in its own family Peltephilidae by Darin A. Croft, John J. Flynn and Andre Wyss.[5]
Distribution
Fossils of Peltephilus have been found in:[6]
- Argentina – Sarmiento Formation
- Bolivia – Salla Formation[7]
- Miocene
- Argentina – Colloncuran Collón Curá Formation and Santacrucian Santa Cruz Formation[8]
- Bolivia – Colloncuran Nazareno Formation
- Chile – Santacrucian Chucal Formation[5]
