 My initial reaction was to be stunned considering the specimens and 
 pictures of specimens I've seen of Placenticeras (UK, Pierre Shale) 
 that had to have been chomped.

 Of course, a mosasaur tooth in shell would help immensely.<


I have also seen the aligned puncture marks in the form of mosasaur jaws. 
 Perhaps some, but not all, such features are limpet attachment scars.

Ammonite shell fragments in a mosasaur would also help resolve this.
