Pygmy hippopotamus Pygmy hippopotamus The pygmy hippopotamus ("Choeropsis liberiensis" or "Hexaprotodon liberiensis") is a small hippopotamid which is native to the forests and swamps of West Africa, primarily in Liberia, with small populations in Sierra Leone, Guinea, and Ivory Coast. The pygmy hippo is reclusive and nocturnal. It is one of only two extant species in the family Hippopotamidae, the other being its much larger relative, the common hippopotamus ("Hippopotamus amphibius") or Nile hippopotamus. The pygmy hippopotamus displays many terrestrial adaptations, but like the hippo, it is semiaquatic and relies on water to keep its skin moist and its body temperature cool.
Patagonia (mammal) as opposed to earlier forest environments in the region. This coincides with "Patagonia"'s burrowing, grazing habits. A large variety of mammal species are known, including caviomorph rodents such as "Dudumus", as well as the rodent-like argyrolagoidean paucituberculates. "Patagonia" likely avoided competition in its fairly specialised niche. Patagonia (mammal) Patagonia is an extinct genus of non-placental mammal from the Miocene of Argentina. Traditionally considered a metatherian "incertae sedis", more recent analysis have shown it to be a gondwanathere. It is the youngest allothere species known. Currently, a single species is known, "P. peregrina", hailing from the Colhuehuapian-dating deposits of the Sarmiento
