Tsaidamotherium is closely related to what mammal from the family Bovidae?
Tsaidamotherium Tsaidamotherium is an extinct genus of Late Miocene ovibovinid caprid from the Tibetan Plateau of Northwestern China. Both known species are extremely unusual in that the horns are of unequal sizes: the left horn core is several times smaller than the right horn core. The closest living relative of "Tsaidamotherium" is probably the Muskox, "Ovibos moschatus".
Iberodon Iberodon is a small, extinct mammal of the Lower Cretaceous from Portugal. It was a member of the also extinct order Multituberculata, and led its obscure and plant-eating existence in the company of dinosaurs. It lies within the suborder "Plagiaulacida" and family Pinheirodontidae.
