Tyler's mouse opossum
Tyler's mouse opossum (Marmosa tyleriana) is a South American marsupial of the family Didelphidae.[2] It lives in rainforests of the Guiana Highlands of southern Venezuela at elevations between 1300 and 2200 m.[1] The species has only been found on three isolated tepuis (Auyantepui, Marahuaca and Sarisariñama).[1] All three of these locations are in protected areas (Canaima, Duida-Marahuaca and Jaua-Sarisariñama national parks).The Latin species name refers to the habitat in which the opossum was first found, a Tyleria forest.In turn, both the genus Tyleria and the opossum's common name refer to Sidney F. Tyler, an American historian and photographer who helped finance the 1928-29 expedition of the American Museum of Natural History to the headwaters of the Orinoco, during which the opossum was discovered.
