This carnivore coprolite was found in the Bull Canyon Formation (Upper Triassic - Norian), Quay County, New Mexico. It contains numerous fine, boney inclusions (white). There also appears to be a small jaw inclusion that has a shape similar to amphibians. Originally, I couldn't figure out why there would be so many finely crushed bones. It is not something I usually see. When bone fragments are present, they are usually larger. That said, fibrous osteoderms are also found in the same area. I have included an image of a fairly large one. They are made up of fine, boney fibers that have a configuration similar to woven fiberglass. So here is what I am wondering: 1. Could the fine bone fragments be the indigested remains of these boney osteoderms? Perhaps from juveniles? I do have some small fragments (somewhere), so I could dissolve them to see how they fall apart. 2. Does anyone know what type of animal had these fibrous plates? All I could find is information on osteoderms from phytosaurs and aetosaurs. Neither of those appear to be fibrous. I have found osteoderm fragments of that type in coprolites, but they look nothing like this. I know some of the Triassic amphibian-like tetrapods had osteoderms, but I haven't been able to find information on these. Since the shape of the jaw in the coprolite has a similar shape to those animals, I'm thinking they may have had this type of osteoderm. Of course more than one type of prey may have been on the menu.
