The skull of the brown bear was received from the Kostroma oblast. The bear was shot by a poacher who was later detained by the inspectors of the state hunting supervision. The skull was given to the employees of the museum who were on an expedition in the Kostroma oblast.
The brown bear is the most common species among bears. There are a few subspecies of the brown bear differing in size and colour. The smallest specimens live in Europe and the largest can be found in Alaska and Kamchatka inhabited by giant bears weighing up to 600-750 kg.
The maximum recorded weight of a male Kamchatka bear is 600 kg; the medium weight is 350-450 kg. The European brown bear usually weighs about 200-300 kg. The weight of bears in Central Russia is 400-600 kg.
