粗尾鼠负鼠属（Thylamys，[1]白鼠负鼠），哺乳纲的一属，而与鼠负鼠属（白鼠负鼠）同科的动物尚有林负鼠属（安氏负鼠）、短尾负鼠属（短尾负鼠）等之数种哺乳动物。
形态描述
[编辑]本属物种的前上颌骨是圆的而不是尖的。雌兽有育幼袋，而且其乳头在腹部排成对称的两排 [2]。除T. macrurus以外，其余物种皆以其尾部储存脂肪[3]，尽管可能这并不适7于所有同属物种[4]。

化石物种
[编辑]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 of 哥伦比亚.[8] Genetic studies indicate that the genus may have originated around 14 million years ago.[9]
