No probs! I have another ammonite (Ataxioceras) with a bite taken out of the back end of the body chamber (attached, there's a better photo of this somewhere, but I can't find it).
Ramses' catch and bite technique makes this story quite vivid:
You gotta collect a lot of fossils for a study like that. I have found very few that are broken in the same spot as those, so I guess the squid over here were either non-existent or just didn't eat ammonites.
but over in North Dakota, South Dakota and Montana in the Cretaceous scaphitid ammonites "healed injuries, as well as lethal injuries, are common on adult shells, especially on the adapical end of the body chamber."
