The frozen bodies of a young woolly mammoth (Mammuthus primigenius), a wild horse (Equus sp.) and a steppe bison (Bison priscus) were recently found in the northern Yakutia (northeastern Siberia). All specimens have preserved bones, skin and soft tissues. Whereas the woolly mammoth and the Pleistocene horse were represented by partial frozen bodies, the steppe bison body was recovered in an absolutely complete state. All specimens were found frozen in the permafrost, with some of the tissues mummified. The wild horse and steppe bison are of Holocene age, and the mammoth is of Late Pleistocene age.
