The exposition and scientific collection of the Museum of Nature currently holds 16 specimens of the family Ursidae (bears), which belong to three species with 6 subspecies. These samples by systematic group are given in the table. A list of all the data and some measurements is given. The comparison of some craniological measurements of two species Ursus arctos and Ursus maritimus. These species separated from the common ancestor about 2 million years ago. During this time, they have adapted to different conditions of life and nutrition, which is reflected in their measurements. Thus, when comparing the size of angular teeth, there is a noticeable advantage of Ursus arctos, as a predominantly herbivorous animal over the typical carnivorous Ursus maritimus  on average they are 31 percent longer in length. In this case, the width of the mouth over the fangs in Ursus maritimus exceeds the width above the angular teeth in the Ursus arctos on the contrary. Particular attention is given to comparing the volume of the brain cavity as a rather important parameter, which is directly related to the "mental" capacity of animals. This figure in Ursus maritimus is more than double that of Ursus arctos. This indicator compares the bears with other large predators  lions and tigers (bears lead the way in this comparison). The Ursidae family collection is kept in good condition and can be used for both educational and scientific purposes.
