This coprolite contains one larger and multiple small bone fragment inclusions on its surface. The broken surface reveals what looks like sand inclusions in addition to small bits of bone. This was likely ingested incidentally as the animal fed on its prey. Based on its width, it was ejected by an animal no smaller than a medium-sized dog.
