ジョセフォアルティガシア

Josephoartigasia is an extinct genus of enormous dinomyid rodent from the Early Pliocene to Early Pleistocene of Uruguay. Its closest living relative is the pacarana. Josephoartigasia is named after Uruguayan national hero José Artigas. It contains two species: J. magna, described in 1966 based on a left mandible, and J. monesi, described in 2008 based on a nearly complete skull. Both are reported from the San José Member of the Raigón Formation by the Barrancas de San Gregorio along Kiyú beach.
