Are modern crocodilians definitely primarily scavengers? We've all seen

The argument is not that crocs are scavengers -- the argument is that a
critter that eats a lot of bone evolves very strong acids -- hence, the
presence of bone preserved in the gut indicates that bone was not very
important as a dietary component, which seems unlikely in a scavenger.
Like hyenas. What other mammals have strong stomach acid? My dog eats
bones (ribs, pork chops) but chews and grinds them.
There's bird pellets... any dino pellets been found?
