Patagonian opossum Patagonian opossum The Patagonian opossum "(Lestodelphys halli)" is the sole species in genus Lestodelphys. The Patagonian opossum occurs further south, in Argentina, than any other living marsupial. Although distributed throughout some parts of southern Argentina, it is one of the least known mammals of South America. They have been spotted near Monte Phytogeographic Province, and in Patagonia Phytogeographic Province, yet there are no records of Patagonian opossums in central Patagonia, which leads mammalogists to believe that they can only live in the Patagonian steppe. There are two areas in the Patagonian steppe where these animals are often found: the province
Patagonian Desert contributing to the gravel sediments covering parts of the Patagonian. The desert is quite windy as well, a result of the rain shadow effect and descending cool mountain air. This wind helps make the Patagonian one of the largest sources of dust over the South Atlantic Ocean. On the west the Patagonian grasslands portion of the Patagonian Desert are bounded by nothofagus forests of the Magellanic subpolar forests. Volcanic rocks covers more than 120,000 km of the Patagonian Desert, mainly in the "Somun Cura Massif" (i.e. North Patagonian Massif) and the "Deseado Massif". Some other volcanic areas include the Pali-Aike
