Can anyone identify this tooth?

[TacOps]

Hi,

I found this tooth while diving the other day, and I'm not sure what it came from, and neither does anyone else I've talked to. Does anyone have an idea? If not do you know of anyone I can send the picture to and get it identified?

Thanks

Looks like a lower jaw bone to me.

looks like the lower jaw bone of a primitive deer or horse like animal

Definitely looks like a jaw.

Put a quarter or something in the pic for perspective.

That was my first thought as well, a broken off jaw bone.

I'm quite certain that this is the left side mandible (lower jaw bone) of a rodent. On your picture the part at the very bottom is where the long lower teeth would grow out of.

I'm not a biologist and there's no reference for size on your picture so I can't make a guess as to which animal it came from. Given the shape of the back teeth I'm thinking mouse or rat depending on how big it is.

Debra is one of the best in the business at identifying fossils. Drop her an email. Tell her I sent you, if you like.

Definitely a jawbone. I found a similar piece in Devil's Den a few years back. Mine was from a rodent size animal.

Can't tell the size, if it is around 1.5"-1.75", it looks like a broken piece of a muskrat jaw?
