Ok so to start off with this, I’m going to post my finds from a recent trip to the outer banks of North Carolina. I was very disappointed to be going to this location at first, because I had no idea of its fossil significance. I wanted to go further down south where the sharks teeth get huge, but the cases further down for Covid 19 were very high and I didn’t want to risk catching the virus so the whole group (who were all my neighbors) decided to head here instead. The first day on the beach, I found a lot of fish fossils (including those vertebrae’s) but it was the second day that was the best. I came across a canine jaw! With the teeth still inside it. It was just sitting in the gravel where I searched for shark teeth and I was so happy of my find because I knew it was something good. As the days went on, I kept finding more evidence of land mammal fossils here, including an astragalus, a scute for a mammal of some sort, crab fragments, fish bone, and a lot more! I have to say, in my years of collecting North Carolina I’ve never come across such an abundance of land mammal fossils in one week. The one question I have, however, is if there is any way you guys could help me identify the species of the jaw? I tried to look for fossil formations off shore but I can’t find any links leading to what this came from. I tried looking at land mammal fauna’s of N.C. but it pulled up nothing. Is there any way to get a specific ID on this jaw?

Thanks for all the input and the cropping guys! I think it’s a dog too but I would want to know if there is any way to specifically identify this jaw to a species.

Given that it is a partial jaw showing significant wear and the variability in domestic dog jaws, I'd be surprised if you could be very certain on a species.  The relatively small size alone make me think dog (Canis familiaris) but certainly a small coyote is not out of the question.

I think I may have figured it out. It looks like a skunk jaw more than a dog. I’m going to do research on Pleistocene skunks and see what I find.

The jaw appears to be from a river otter, Lutra sp.

If it is a river otter, that's pretty sick. I don't have one of those in my collection so that actually pretty exciting!

 

Thanks for the ID, Harry!

I do not believe that a skunk (unless skunks were a lot bigger in the past) based on size, shape of the lower margin and the coronoid process!  Your partial jaw is over 2 inches long.  I can buy into the whole river otter ID in looking at the shape of the coronoid process and the teeth.
