Patagonian bonneted bat it is not thought to be in rapid population decline. Patagonian bonneted bat The Patagonian bonneted bat ("Eumops patagonicus"), also called the Patagonian dwarf bonneted bat, is a species of free-tailed bat found in Argentina, Bolivia and Paraguay. It was described as a new species in 1924 by British zoologist Oldfield Thomas. Thomas had obtained the holotype from Argentinean-Italian scientist Roberto Dabbene, who worked in Buenos Aires at the time. Its species name ""patagonicus"" means "belonging to Patagonia." The Patagonian bonneted bat was widely considered a subspecies of the dwarf bonneted bat ("Eumops bonariensis") from approximately 1932 until the 1990s.
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
