World's largest dinosaur tooth marks found in South Korea

South Korean researchers said Monday that they have discovered the world's largest fossilized tooth marks of a carnivorous dinosaur in the country's southeastern province.



The unusual tooth scores, found on the tailbone of the adult herbivorous dinosaur Pukyongosaurus from the early Cretaceous period of the Mesozoic Era, measured 17 centimeters long, 2 centimeters wide, and 1.5 centimeters deep, the longest and deepest scores ever discovered in the world

I wanna know what ate the Pukyongosaurus

Is it possible the length of the gouges was caused by the predator dragging its teeth along the bone in some way?
And also, seeing as they didn't state it came from a deposit formed on land, could the size of the marks not be attributed to a large marine reptile after the body floated out to sea?, although it doesn't explain the size range too well. Don't mean to be pessimistic at all though
