The location of the Chondon mammoth (Mammuthusprimigenius Blumenbach, 1799), in the Ust-Yansky District of the Sakha Republic
The remains of the wooly mammoth Mammuthus primigenius (Blum, 1799) have been found on the right bank of the Chordon River tributary, the site of “Igiannyah”, at the bottom of the Poluosniy Ridge, 66 km south-west from the settlement of Tumat, the Ust-Yansky District. The height of the studied exposure is uneven, of about 20-30 m, its length is 250-300 m. The exposure was formed as a result of defrosting of large volumes of sediments, forming the right bank of the Chordon River. In this article we provide the results of anatomic and morphological examination of bone remnants of the wooly mammoth. Due to the comparative study of the mammoth's remains and similar findings in the same site, we have identified the individual age of the mammoth as 47-50 years old, as well as the approximate proportions of its skeleton. Given that the remains of Mammuthus primigenius were found at one location and have similar size, age indicators (apophysis and epiphysis's sutures are obliterated, radial bone is joined to elbow bone), it may be assumed that the bones belong to one large mature specimen of mammoth, probably an adult male.
