It was originally believed to represent the crushed remains of a single skull, but on closer inspection it was determined to be the remains of a cotylosaur being swallowed by the larger reptile, tail first.
Examples like this point to very rapid burial and fossilization (before the creature had time to rot, or even to finish its lunch!). This contradicts the idea of slow evolutionary processes, but fits perfectly with the creationist model of rapid burial caused by Noah’s Flood and its after-effects.
[The fossil record clearly shows not only death, but a cruel and violent world. Christians who defend long ages and deny the global Flood invariably end up having to believe that this existed long before Adam’s sin could have brought the curse upon creation. See Is Cruelty Normal? p. 19 this issue.—Ed.]
