New data on the morphology of a foetal mammoth (Mammuthus primigenius) from the Late Pleistocene of southwestern Siberia

Twenty-six bones and fragments of bones belonging to a Mammuthus primigenius (Blumenbach, 1799) foetus have been discovered in osteological material coming from the late Pleistocene site of Shestakovo, Chebulinsk area, Kemerovo Province. The age of the site is estimated as 24,000-20,000 years BP (Karginian-Sartanian). The stage of intra-uterine development of the foetus can be estimated as 19-20 months. This foetal skeleton is the most complete of all known foetus materials belonging to this species.
