Unfortunately, not my find, and not bone, but its so cool that its worth a post.
There are dog prints in the ash layer, and the first of their kind that we've found. Unfortunately, can't show a picture. We're used to just seeing these animal's coprolites and borrows, but finally, finally, we found tracks. We're still crossing our fingers for another skeleton...
There is one carnivore in the ash bed so far. It's this guy. He's a little raccoon-sized dog that wouldn't have been able to burrow and thus escape the bad air around him like the larger predators could have. Mike likes to tell people that we are ahead of the game, because normally you find 1 predator for every 100 prey animals of a similar size, and we have 50 individuals in the ash. That being said, this little guy is... well, little, and that doesn't count the fact that we also found 200 full skeletons in the National Geographic quarry... by that ratio, we should have 2.5 predators of similar size to the rhinos. Plus, we know that there are more skeletons to be uncovered. I'll generously assume this guy had a good appetite and call him the 1/2. There was enough here to support two more, and surely at least one of those didn't make it away from the ash.
He's out there.
