          Protohummus dango was a rodent of the Miocene. The systematic paleontology of it is:
       
      Mammalia Linnaeus 1758
      Rodentia Bowditch 1821
      Hystricomorpha Brandt 1855
      Hystricognathi Tullberg 1889
      Phiomorpha
      Thryonomyoidea Pocock 1922
      Thryonomyidae Pocock 1922
      Protohummus Kraatz et al. 2013
      Protohummus dango Kraatz et al. 2013
       
       
          Brian P. Kraatz, Faysal Bibi, Andrew Hill, and Mark Beech wrote an article titled A new fossil thryonomyid from the Late Miocene of the United Arab Emirate and the origin of African cane rats. It was published in 2013 in Naturwissenschaften, Volume 100, Issue 5, pp. 437-449. This quote from the abstract says:
       
      Cane rats (Thryonomyidae) are represented today by two species inhabiting sub-Saharan Africa. Their fossil record is predominantly African, but includes several Miocene species from Arabia and continental Asia that represent dispersals events from Africa. For example, Paraulacodus indicus, known from the Miocene of Pakistan, is closely related to the living Thryonomys. Here we describe a new thryonomyid, Protohummus dango, gen. et sp. nov., from the Late Miocene Baynuah Formation of the United Arab Emirates. The new thryonomyid is less derived than "Thryonomys" asakomae from the latest Miocene of Ethiopia and clarifies the origin of evolutionary transition from Paraulacodus. A phylogenetic analysis shows Protohummus dango to be morphologically intermediate between Paraulacodus spp. and extinct and living Thryonomys spp. The morphological grade and phylogenetic position of Protohummus dango further supports previous biochronological estimates of the age of the Baynunah Formation (ca. 6-8 Ma).
