Well, besides the obvious, could you elaborate on this
statement? Have you found something conclusive (i.e.
Carch teeth lodged in sauropod bone)? This would be

I suggest that S. would go for fish and
ornithischians. Not an exclusively piscivorous diet.
Baryonyx (which seems far more suited to catching
fish) wouldn't hesitate to kill a juvenile iguanodont,
so I see no reason to assume otherwise regarding
Spinosaurus. Kind of like the T.rex-as-scavenger
hypothesis....no large carnivore feeds only carcasses.
Likewise, no spinosaurine would feed only on fish.
