This one really has me stumped. Picked it up a couple of weeks ago on a Peace River hunt. I have searched mammal bone, fossil ear bone and other variations on search criteria and can't come up with anything that looks similar. Maybe because it is just a partial of something that is not a common find in the river? If anyone has any ideas I would love to hear them. The specimen is just over 1" square with several holes/channels. Thanks for any help.
