Sharks are among the largest scavengers in the sea, and when they get their fill they often shed a few teeth. Which is also what happened in this case. and it is by it's teeth that we know the shark.

In fact two types of shark teeth were found with bones of this Progathodon, one type belonged to the 3 meter long Squalicorax while other teeth belonged to the smaller Plicatoscyllium. Both species would certainly have been small enough to be considered a snackfood by P. saturator when it was alive.

The scavenging sharks also inspired the species name saturator, which according to the paper describing it means "he who gives satisfaction (both to Maastrichtian sharks as well as Recent palaeontologists)".
