Rodentia; Heptaxodontidae

    The largest of the Jamaican endemic mammals, Clidomys is a poorly-known genus with two nominal species. Only two dated localities are known, and both have provided dates that preceed or overlap the Sangamonian Interglacial at ~125,000 yrbp. There is no current evidence that Clidomys survived into the terminal Pleistocene or Holocene. Clidomys is a heptaxodontid rodent, closely related to Elasmodontomys of Puerto Rico and Quemisia of Hispaniola.
