This is what the Oreodont skull looked like when I discovered it on the 4th of July in the white river formation of Wyoming. I spotted it from quite a distance, as the colour of the skull really stood out from the background. 

You can already see the eye socket and most of the upper skull. After a little bit of digging, I discovered that most of the lower jaws were still there as well, which I got very excited about as this was the first oreodont skull I had found that still had the lower jaws.

The lower jaws were found loose from each other, which is unusual as they are almost always stuck to the skull if they are present. This presented me with a unique opportunity to prep the lower jaws completely loose from the skull.

After about 50 hours of preparation this is what the skull looked like. By this time, I had finished one of the lower jaws, as well as the back of the skull.

 

All in all, the preparation took way longer than I expected, taking about 100 hours in total. But I'm very happy with the end result and it definitely is one of my favourite pieces.
