What you have here are Chinese statues indeed made of bone and made in second half 20th century. I see them a lot and they are sold as decorative statues for export to western countries mainly. They were sold as a pair of royal statues and sometimes called made of Yak bone ( a buffalo from Tibet ). I do not think they are made of Yak bone but just cow bone.
