粗尾鼠负鼠属

粗尾鼠負鼠屬（Thylamys，白鼠負鼠），哺乳綱的一屬，而與鼠負鼠屬（白鼠負鼠）同科的動物尚有林負鼠屬（安氏負鼠）、短尾負鼠屬（短尾負鼠）等之數種哺乳動物。 本屬物種的前上頜骨是圓的而不是尖的。雌獸有育幼袋，而且其乳頭在腹部排成對稱的兩排 。除T. macrurus以外，其餘物種皆以其尾部儲存脂肪，儘管可能這並不適7於所有同屬物種。 現時本屬包括下列各現生種： Cinderella fat-tailed mouse opossum（英语：Cinderella fat-tailed mouse opossum） (T. cinderella) (Thylamys citellus) Elegant fat-tailed mouse opossum (T. elegans) (Thylamys fenestrae) Karimi's fat-tailed mouse opossum（英语：Karimi's fat-tailed mouse opossum） (T. karimii) Paraguayan fat-tailed mouse opossum（英语：Paraguayan fat-tailed mouse opossum） (T. macrurus) Olfers 1818 White-bellied fat-tailed mouse opossum（英语：White-bellied fat-tailed mouse opossum） (T. pallidior) Thomas 1902 (T. pulchellus) Common fat-tailed mouse opossum（英语：Common fat-tailed mouse opossum） (T. pusillus) Desmarest 1804 Argentine fat-tailed mouse opossum（英语：Argentine fat-tailed mouse opossum） (T. sponsorius) Tate's fat-tailed mouse opossum（英语：Tate's fat-tailed mouse opossum） (T. tatei) Dwarf fat-tailed mouse opossum（英语：Dwarf fat-tailed mouse opossum） (T. velutinus) Buff-bellied fat-tailed mouse opossum（英语：Buff-bellied fat-tailed mouse opossum） (T. venustus) Thomas 1902 Fossils belonging to the genus date back to the 中新世, with the oldest specimens being found in the Cerro Azul Formation of 阿根廷 and the Honda Group（英语：Honda Group, Colombia） of 哥伦比亚. Genetic studies indicate that the genus may have originated around 14 million years ago. Fossil species: T. colombianus Goin 1997 T. minutus Goin 1997 T. pinei Goin et al. 2000 Gardner, A.L.
