How much fossil evidence has been left behind indicating struggles between predator and prey in the age of the dinosaurs? Like, say, a theropod with a shattered leg from an ankylosaur tail. Or stab wounds from a triceratops horn.
I would imagine if the theropod won, the herbivorous dinosaur would be reduced to pretty much nothing in the process of digestion. But I have a vague recollection of “healed wounds” on some ceratopsians. My memory may be playing tricks on me, though…
