Coprolite or Cololite with Gar Jaw and Tooth Inclusions

This specimen is very friable. It contains scales, bone fragments, vertebrae, and fish jaw fragments with teeth. The larger jaw fragment appears to be that of a small alligator gar. Based on its shape, amount of undigested bony inclusions and somewhat loose composition, it is possible that this is a cololite rather than a coprolite. Cololites are similar to coprolites, except they were never expelled (pooped).  The holes in this specimen could be impressions from the teeth of a predator chomping down on the abdomen of a creature.
