Osborn s Key Mouse

Osborn's key mouse (Clidomys osborni), also known as the larger Jamaican giant hutia, is an extinct species of large rodent in the family Heptaxodontidae. It was endemic to the island of Jamaica and likely became extinct before the end of the Pleistocene. Osborn's key mouse has only been found in six caves: Wallingford Roadside Cave, Sheep Pen Cave, Molton Fissure, Worthy Park Cave 1, Luidas Vale Cave, and Slue's Cave.
