So what do we have here? If you aren't already familiar with the term regurgitalite, it is just a fancy word for fossilized vomit. This one is full of undigested bone. How can we tell the difference between a carnivore coprolite and regurgitalite? Well, the bones in coprolites are generally surrounded by phosphatic material...the remains of what was more fully digested. This pile is just bones and scales. If you look closely, you can see that the longer bones pretty much face the same direction. This tells us that it likely came up in a clump, similar to the pellets regurgitated by some birds. That clump was covered quickly, before it was moved around by ocean currents.
