Abstract
Cane rats Thryonomyidae are represented today by two species inhabiting subSaharan Africa Their fossil record is predominately African but includes several Miocene species from Arabia and continental Asia that represent dispersal events from Africa For example Paraulacodus indicus known from the Miocene of Pakistan is closely related to living Thryonomys Here we describe a new thryonomyid Protohummus dango gen et sp nov from the late Miocene Baynunah 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 crown Thryonomys and the 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
