Новосибирские острова
As noted by Baron Eduard V. Toll in his account of the New Siberian Islands, sizeable and economically significant accumulations of fossil ivory occur within them. The ivory, along with mammoth and other bones, are found in recent beaches, drainage areas, river terraces and river beds. The New Siberian Islands are unique in the burial and preservation of fossil ivory "in such a wonderful state of preservation that the tusks so found cannot be distinguished from the very best and purest ivory".
