Patagonian mara to the anus. The Patagonian mara is found only in Argentina. It ranges from 28ºS to 50ºS. Maras prefer to live in habitats with lots of shrub cover. However they also inhabit overgrazed and barren soils in the Monte Desert biome. In northwestern Argentina the mara primarily inhabits lowland habitats like forest and creosote bush or "larrea". Maras prefer sandy and low shrub habitat in Valdes Peninsula. It has adapted well to a cursorial lifestyle on the open plains and steppe, with its long legs, reduced clavicle and well-developed sensory organs making it capable of running and communicating in these
Patagonian Ice Sheet than the extremely steep ones of present-day Patagonia. Unlike the Laurentide Ice Sheet or the ice sheets of Northern Europe, the Patagonian Ice Sheet did not cause major extinctions or loss of biodiversity. This is because the flora remaining to the north of the ice were isolated by the Atacama Desert and were able to speciate easily wherever suitable microclimates occurred. In fact, most of the original Antarctic flora survives today on land occupied by the ice sheet. However, there are indications that during the last deglaciation (17,500 years ago), the rapid melting of the northernmost extension of the Patagonian
