Iam sure it is not a bear skull,i have two of my own bear skulls sitting in front of me and they don't look like any thing like the picture,where the nose meets the forehead it is too steep of a slope,you need to measure the length of the skull.a blackbear could be any where from 10 inches long to 12 inches. 10 being very small and 12 inches being big and also measure the width.and let us know what you come up with.
