I could be wrong, but it looks like a naturally formed piece of jasper to me.

Boy I don't know. To me it has some looks of a sharks tooth and some of it doesn't look like the tooth of a shark. I'm leaning towards it being a piece bone fragment.

Looks like the bone inside the hoof of a cloven hoofed animal, perhaps deer, antelope, mountain goat or sheep. On a horse that would be the "coffin bone." The distal phalanx, relates to the last bone in your finger, the bone under your finger nail.

That's very interesting. That would make sense being in the mountains where we live.

Not like any shark tooth I have ever seen and I have seen a lot of shark's teeth. I think Bosn nailed it..

What you have there is the toe bone from a deer, as BostonMate suggested.

Here's a couple of pictures.
These are deer feet, note the cloven foot, under each of
those pointed hoof walls there is a bone. The pastern bones would be doubled.

This side view shows the bone in the toe, but doesn't show the pastern bones. I know a little about a horses foot, but on cloven hoofed critters I don't know what they
call the bones. On a horse there would be the coffin bone, then the short pastern, long pastern, then the cannon bone and those aren't shown in the diagram of the sheep's foot diagram. On a cloven hoof I think there are 2 short and 2 long pastern bones, and then one cannon bone.

Wow thank you for all the great information! Now I won't look like a fool bring it into work and saying it's a shark tooth!
