Content
Type instanceHolotype : No. 20557 (177) in the ZIN RAS collection. A fragment of the right branch of the lower jaw with teeth.
In the first description of A. A. Gureev it is said that the location of “ r. Ural , between the village Yanvartsevo and the city of Uralsky ” [1] , with I. M. Gromov and G. I. Baranova, referring to the same copy with the same number, it is said that he found the “ Kostenki-IV ” site, p. Aleksandrovskoe, Voronezh region " [2] [3] .
DescriptionThe dimensions are very large, 1/10 larger than the largest modern specimens of the hare . Lower jaw with high tooth. In the third premolar, the height of the lower jaw is 16.0-19.8 mm, while in the whitish it is 13.4-14.2 mm. In structure, molars resemble those of modern whites, but they are very massive. All parts of the skeleton are more massive in comparison with the white. In this case, the drum chambers are relatively small. The articular condyle of the occipital bone is narrower than that of modern whites. The length of the lower dentition is 18.3–22.2 mm, the length of the lower leg is 160–195 mm, and the length of the pelvis is 105 mm [4] .
DistributionNovgorod-Seversky , Voronezh Oblast ( Kostenki ), Southern [4] and Northern Urals , Eastern Siberia ( Berelyokh ), Chukotka Peninsula [2] , Lena River Delta, Arctic coast of Yakutia and Novosibirsk Islands [5] .
Some Ecological FeaturesThe structural features of the jaw indicate a strong development of chewing muscles. High crowns of massive indigenous, sharply bent up incisal part of the lower jaw indicate roughage nutrition [4] .
DNA researchModern studies of a small fragment of the mitochondrial DNA of Don hares have confirmed their unconditional proximity to modern whites [6] .
