What is "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 Takin, Budorcas taxicolor.
