A skull of a woolly rhinoceros (C. antiquitatis) is described, which was found in 2018 on the bank of the Kozhevena river in the North of the island of Kotelny (the New Siberian Islands archipelago) during the expedition of the Department of mammoth fauna research of the Academy of Sciences of the Republic of Sakha (Yakutia) and the Borissiak Paleontological Institute (Moscow). A comparative analysis of craniological features of the skull is presented in comparison with three skulls of C. antiquitatis from the continental part of Yakutia (Megino-Kangalassky, Nizhnekolymsky and Abysky districts). The woolly rhinoceros differs from other modern and extinct rhinoceros species by having a completely ossified nasal septum. Ossification of this septum in this species proceeds with maturing and, in addition, is determined by the intensity of horns use in the extraction of foot food. The nasal septum of the test sample was not completely ossified (about 80 %). Apparently, this individual was sexually mature but not old. The development of exostoses shows that this was a young male. At the moment, this is the northernmost find of the remains of this species. At the end of the upper Pleistocene, the New Siberian Islands were part of the mainland. The distribution of C. antiquitatis seems to have reached the Northern borders of the Beringian landmass.
