Hello, a friend of mine has found a beautiful very old bear skull in his grandpa's house (see pictures). He used to hunt in British Columbia, Canada, long ago. Now we would like to know what type of bear it is. The skull is 12 10/16 (32.2 centimetres) in length and 8 4/16 (21 centimetres) wide. Its molars are large and flat and highly worn down, meaning that the animal must have been old. I have read that it is possible to determinate the species by molar size, but we don`t know how exactly. The molars are up to 1 6/16 (3.5 centimetres) in length. We would be happy if you could tell us whether it is an old male black bear or an old female grizzly (its too large for female black and seems too small for male grizzly).
